I think my breastfeeding journey with DS is about to end. We are down to one feed during the day before his nap and one feed at night before bed. Sometimes he doesnt have boob for his day nap though. He was a complete boobaholic so I never thought this day would come.
I don't actually think I have any milk at the moment and he doesn't suckle for long, just latches on and then falls asleep.
I have found being pregnant and breastfeeding mostly painful but it has improved over the last few weeks.
I was talking to a couple of mums, one who has a boy who is a month older than mine and she said she will be "devastated" when her son weans and at the moment she loves the fact that his main source of food is still breastmilk (he is 17 months).
Another mum said she felt sad but wasn't heartbroken when her 19 month old weaned.
If you had asked me a few months ago I would have said "I can't ****ing wait to finish breastfeeding" because DS was latched on all night, waking 2 hourly, needed to be fed to sleep and still feeding ten million times a day and night, plus the pain meant I was completely fed up.
Now that his sleep has improved and we aren't feeding much, I wonder if I should just wean him completely as I probably could get him to sleep without boob. I'm not devastated that our journey is ending but I there is something holding me back from weaning. I'm not sure what.
How did you feel when your breastfeeding journey ended? How old was your baby/toddler?

I loved our breastfeeding journey, however I opened an expensive bottle of champagne when it ended at 14 months. We did not pre plan it, we had reduced to the bedtime feed as I went back to work at 11 months and one night we just read stories instead and sort of forgot. Like a natural end.
Did drink a lot of wine the week after

DD is 25 months and is on one feed a day. At Christmas time she was demanding to be fed all the time and I was absolutely driving me insane. I had to start weaning her through the day otherwise it was tantrum after tantrum plus I had the idea in my head that I would like to wean her around 2. I then cut her morning feed which was a lot easier in comparison. I am still hanging on to this last feed as much as her I think! I do plan to cut out her night feed by the middle of the year. I feel sad about weaning her, rather like the feeling when I think of her going to school or something like that. It is more to do with the realisation she is growing up and no longer a baby.

My son recently weaned himself at just a smidge over 21 months. He had been down to a feed before bed and a morning feed for a few months, then fairly abruptly stopped his night feed and had only a morning feed for a couple of months, and then abruptly stopped his morning feed and hasn't looked back.
I had some mixed emotions, but overall it was a positive experience. We had a very tough start to breastfeeding and I worked damned hard and had a lot of great support to establish it. I had very much wanted to make it to two years as per the WHO guidelines, so felt a little disappointed, but used the time when he was dropping feeds to 'prepare' myself that we would likely not be getting to the two year mark. (I generally don't deal well with not meeting goals I set for myself- parenting has been a challenge haha!) I think some bum advice I received from a baby clinic nurse when he started solids may have had a flow on effect which resulted in the weaning prior to tow years, and I made my peace with the idea that I did the best I could with the info I had at the time.
My overwhelming feeling though, is being pleased that he had stopped in his own time, when it must have felt right for him. Now that he's done, I'm also noticing a small but distinct change in feeling like my body is just mine again- no worrying about what I'm eating or drinking or putting on my skin etc. And also enjoying a little less physical drain, as I think even when it was only once a day it still put another demand on my energy levels, although small.
I hope that helps. Congrats on feeding this far

I struggled to BF my first baby and I was sad to stop at 5 months, but it was definitely the right decision. I weaned #2 at 11 months so that I could have a minor operation, which didn't end up happening then because I found out I was pregnant with #3 just beforehand. I BF #3 to 17 months. By that stage, it was a morning feed and an evening feed, and one day when she fussed over the morning feed, I just thought that I'd had enough. At that point, I'd been pregnant and/or breast feeding for over 3.5 years and I was ready. I gave her one more short feed about 3 days later (for my benefit, not hers) and that was it.

DS is 12 months and I can't see myself weaning any time soon. Just today he came down with a bit of a cold/flu and I was so thankful I was still breastfeeding! Or yesterday, when he crawled under the dining table and then abruptly stood up, slamming his head into the tabletop, I put him on the boob before we had a chance to start screaming, and no tears! It's just such a magic cure-all.
And to be honest, I love how he snuggles into me, all curled in, still such a baby. I know I will miss these quiet, snuggly times! He never stops otherwise.

My son is dropping his last feed (bedtime). Refused it about a week ago, and fell asleep easily. Wanted it again for 5 nights, said no last night, cried for an hour (despite cuddling, patting etc) then asked for it and fell asleep, refused tonight, cried but finally settled with patting. I'm happy/sad for the usual reasons, but also really upset that we are back to crying at bedtime. It does my head in.

i rejoiced!
DS fed until i was 6 months pregnant, and then DD fed until 17-ish months, so i spent a good 4.5 years being either pregnant, breastfeeding or a combo of both, and i was ready to have my body back
Posted 17 February 2013 - 07:32 PM
I was very surprised how emotional I was. I reluctantly weaned at 14 months to go back for more IVF. I felt anxious the whole week leading up to our final feed. It was his lunchtime BF that he always fed to sleep for. I cried throughout the feed, he fell asleep in my arms and when I put him in his cot I walked out of the room and sobbed. We really struggled at the start and I honestly, truly loathed breastfeeding. I could never have imagined how much I would come to treasure it and how very sad I would feel 14 months later at our very last feed. It was a very bittersweet moment.

My DS weaned himself at around 14 months (I was in the second trimester of pregnancy #2). I cried my eyes out, but that could have been the hormones adding to the emotion! I was sad, but I had another baby on the way so I knew it wouldn't be long before I'd be breastfeeding again.
My DD is now 12 months (and I'm 24 weeks pg with #3) and I think she's losing interest so will probably wean herself in the next month or two.
I think I'll be fine this time around, but when my last baby weans.... BIG tears, it will be a sad day and I'm not looking forward to it.
Posted 17 February 2013 - 09:04 PM
Hmmm....kind of a non-event for me, too.
I wanted to breastfeed until DD was two years old. Turns out that I got pregnant at a time which coincided with her happily forgetting about feeds, so we've fully weaned now at 22 months old. I'm happy with that and feel like I've pretty much met my goal.

I had a radioactive treatment which effectively rendered my breast milk undrinkable. DS was 16 months and I burst into tears. My health was also poor, so I was emotionally low.
DD was 14 months and self weaned; I loved feeding but was ok for it to end. I thought I'd be more emotional, but after feeding for almost 3 years and being pregnant for 18 months.... I liked my body back!
Posted 17 February 2013 - 09:23 PM
I was so happy when I stopped BF'ding. I felt like I had my body back and could think about me for a change. DS was much happier as well and always loved his bottles so it made things a lot easier when I stopped feeding him myself.
Posted 17 February 2013 - 09:24 PM
My hormones went crackerdog and I ended up with PND each time. DS2 is down to one feed - at bedtime - and as much as I'd like to end it, I'm dreading how my body will react.
Posted 17 February 2013 - 10:14 PM
Mixed feelings for me, I was in the grip of depression and dd suddenly refused to breastfeed at 8 months of age, for the weeks I tried to get her back on the breast I felt so sad and frightened too (she wouldn't take bottle or cup so had milk in all food).
I ended up continuing to express and give her my milk and my feelings changed over time, I got used to not breast feeding, up till then I had limited other settling techniques other than the breast.
Over time my confidence grew and I felt I had learned lots of new ways to relate to dd and enjoyed not breast feeding in one way, seeing her eventually take a cup and eat well.
But there is still some residual sadness at how weaning happened, at what could have been.
Once I stopped expressing it was another layer of freedom that I also appreciated.
Mixed feelings and responses.
All the best Sunnycat.

I thought I'd be more sad than I was actually.
But it was a LONG drawn out process starting at me cutting down her feeds bit by bit then her stopping asking for the last feed eventually.
My daughter was always asking for it but i KNEW she didn't NEED to BF every 2 hours when she was 18 months old, it was a habit for her in some ways, and me too I guess.
I started by cutting night feeds at 18 months, then cut her down to 4 feeds a day, then 3 then 2 over the course of 9 or so months. till she was down to one feed first thing in the morning.
This last Christmas she didn't ask for a feed every day, maybe 2 or 3 times a week, then after new year, I said no, she's nearly 3, she doesn't need milk from me anymore and it was done.
I did enjoy our breast feeding journey, it was really easy for me and her, and I won't be having anymore babies, but it was time to end it and we're ok
She only asked for a feed maybe 3 times after I decided to fully stop, and she got over it within a minute or 2 each time so I knew she was good to wean fully.
All up, I think it took me 12 months easy to fully wean her so it wasn't sudden or unexpected.
She'll be 3 in April. I fed her longer than I was going to, I was going to stop at 2, but we both enjoyed it so I kept going.
Posted 17 February 2013 - 10:38 PM
I was definitely sad for at least 2 weeks. I worried about how it would affect the bond between DD and I.
If you get sad, just remind yourself that you'll have another little baby to feed soon. It will be a brief reprieve so enjoy it while you can

Thanks everyone
It's nice to read other people's experiences.
I think I could push DS to stop if I really wanted to, sometimes I am finding it really painful and I don't actually think I have any milk at the moment anyway. I'm not devastated but I feel like I should be sadder than I am. I think if he were my last I might be more sad but I think I'll be doing this all over again in a few months so maybe that's why I'm kind of "meh" about it.
We've had a really easy breastfeeding journey and we a incredibly close, but I don't think our bond has anything to do with our breastfeeding as DS is a really affectionate and cuddly little boy.

This is a continuation-in-part of U.S. application Ser. No. 840,332 filed Mar. 17, 1986, now U.S. Pat. No. 4,802,757.
The present invention broadly relates to systems for detecting changes in and controlling the attitude of an airborne or spaceborne platform such as an imaging sensor or beam pointer mounted on a spacecraft or aircraft and deals more particularly with a system for detecting and correcting the attitude changes using a terrain imaging technique.
Multispectral imaging scanners are commonly mounted on moving aircraft or satellites for the purpose of recording images of earth terrain as they pass over the earth's surface. The images are recorded as data which consist of a series of scan lines whose relative orientation with respect to other scan lines may change as the aircraft or spacecraft moves along its line of flight. The attitude of aircraft and spacecraft is subjected to perturbations induced by roll, pitch, yaw, altitude, and velocity changes which introduce non-systematic geometric distortions into the image of the terrain. In the case of aircraft, such perturbations result from wind buffeting, changes in air density and inadvertent course changes. Perturbations in a satellite environment are more subtle, but can also result from atmospheric buffeting (in low altitude orbit), orbital control maneuvers, and changes in the satellite's center of mass (i.e. fuel consumption, antenna and solar array orientation changes).
In order to correct the geometry of the "raw" image data, it is usually possible to identify pixels with ground control points on maps for every few scan lines in the image data by searching maps for the exact location of features which are distinct pixels (picture elements) in the image data, then mathematically warping and resampling the entire image to arrive at the best fit for all the ground control points. However, this approach is especially expensive in terms of the time and labor required to manually correlate the recorded image data with the position of ground control points, and the correction relies exclusively upon the accuracy and density of the ground control. Another solution to this problem involves horizon seekers, star pointers and inertial navigation systems on-board the spacecraft or aircraft. These attitude sensors detect and record attitude change data required for the partial geometric correction of image data. Such data is not optimal for at least three reasons: first, they use features or inertial references which are not an intrinsic part of the recorded terrain data; second, they can cost as much as the primary sensor; and third, their weight and power consumption maybe prohibitive for some applications.
Consequently, there is a need in the art for a lightweight, more efficient, and less expensive system for detecting and recording the attitude changes of a platform, such as an imaging sensor platform, which can be used either for aircraft or satellite terrain image sensor applications.
The problems of accurately determining changes in the attitude of an airborne or spaceborne platform discussed above are also applicable to other uses of such platforms, such as mounting an energy beam pointing device which may comprise, for example a mirror arrangement to reflect energy beams, or an antenna employed to receive or transmit energy in the radio frequency spectrum. In many applications, minute changes in the attitude of the beam pointing platform can have a major impact on the aiming accuracy of the beam pointer where extremely precise pointing accuracy is required. Attitude control systems for correcting and altering the attitude of beam pointer mechanisms of course require dynamic, real time control, thus dictating a system capable of quickly detecting minute changes in platform attitude and dynamically controlling servomotors quickly after the attitude change has been sensed in order to re-aim the energy beam.
The above problems of determining changes in platform attitude are exacerbated by atmospheric or geological characteristics that interfere and sometimes prevent a complete "snap shot" image from being formed of the entire area of the earth beneath the aircraft or spacecraft. For example, the area of the ground within the field of view beneath the spacecraft or aircraft may not be completely visible due to cloud cover or the presence of a body of water, which make it impossible to measure changes in platform and attitude and altitude, even through there may be some area on the ground within the field of view of the imaging sensor which exists either between the clouds or on either side of the body of water for which imaging data can be generated. However, in the past, under these circumstances, the data so acquired by the primary imaging sensor corresponding to images within the sensor's field of view that are between clouds or on the other side of a body of water is discarded because the overall data set for the entire field of view does not possess sufficient quality for mapping purposes. Accordingly, it would be desirable to employ a method of determining and altering the attitude of the platform which is not dependent upon requiring an entire set of "good" mapping data from the primary sensor's full field of view, but rather is effective through the use of only a partial data set, the data corresponding to images of that portion of the ground within the field of view that can indeed by "seen" by the sensor which is not otherwise obscured.
According to one aspect of the present invention, a system for determining the attitude changes of an air or spaceborne terrain imaging sensor platform or energy beam pointing platform includes a second sensor, preferably comprising a two-dimension panchromatic image sensor, and a digital image correlator used to compare successive, overlapping and instantaneously acquired two-dimensional image terrain data. The second sensor generates a series of master and slave images, with each slave becoming a master when a succeeding slave image is produced. Digital image correlation is performed in order to identify a plurality (preferably five) of pixels on the master image with the same geographic points on the slave image. The correlation is performed by selecting a plurality (preferably five) of spatially distributed patches of pixel arrays in the slave image, and then moving these arrays about the master image in order to find the gray scale correlation coefficient for each patch. The locations with the highest correlation coefficients are selected as the true locations of the slave patches relative to the master image. The row and column of the correlated pixels in the slave image are recorded and the relative orientation of the slave image with respect to the master image is found using the coplanarity condition of photogrammetry. The relative orientation of the master and slave images uniquely characterizes the new attitude of the sensor platform, i.e. the change in platform attitude between the points in time at which the master and slave images were recorded. The data acquired with the two-dimensional imaging sensor may be stored for later use, or it may be processed in real time to obtain information which characterizes the changes in the sensor platform and correct geometry of the terrain image data recorded by the primary sensor. The information regarding changes in platform attitude and altitude may be employed to reposition the energy beam pointer.
According to another aspect of the invention, a method is provided for adjusting the pointing of a device for reflecting or originating a beam of energy, wherein the device is carried on a platform of an airborne or spaceborne craft which travels along a flight path above the surface of the earth and experiences changes in attitude or altitude which affect the direction that the device is pointed. The method includes the steps of generating a first set of data representing picture elements of a first two-dimensional image of the surface area at a first point along the flight path such that the data representing all of the picture elements of the first image are generated substantially simultaneously, generating a second set of data representing picture elements of a second two-dimensional image of the surface at a second point along the flight path closely spaced from the first point such that at least a portion of the images overlap each other, correlating a plurality of corresponding picture elements of the first and second images in the overlapping portion thereof such that the relative positions of the correlated picture elements represent the changes in attitude or altitude, generating a set of data representing the changes in attitude or altitude of the platform based on the correlation results, and then altering the attitude of the platform or beam-pointing mechanism so that the device points the beam of energy in the desired pre-selected direction using the data thus generated.
In accordance with a further aspect of the invention, a method is provided for determining changes in the attitude or elevation of a platform carried on an airborne or spaceborne craft which is similar to that described above, but further includes the step of analyzing the regions ahead of the craft to identify unobscured surface areas which include features from which data may be generated related to the attitude and altitude of the platform. This analysis is preferably performed using a multispectral scanner which scans a path ahead and traverse to the flight path of the craft. Upon identifying unobscured surface areas ahead of the craft, such surface areas are imaged on to a sensor, notwithstanding the fact that the areas immediately beneath the craft may be obscured or contain featureless or dynamic surface areas such as bodies of water or bodies of clouds.
Finally, still further aspect of the invention resides in an apparatus for determining changes in the attitude or altitude of a platform carried by an air or spaceborne craft which implement the methods described above.
Accordingly, it is a primary object of the present invention to provide a system for detecting changes in the orientation of a moving air of spaceborne platform, such as a terrain imaging multispectral scanner (sensor) or an energy beam pointer, which is particularly simple, accurate, cost effective and reliable.
A further object of the invention is to provide a system of the type mentioned above which is capable of dynamically controlling the platform substantially simultaneously with the detection of changes in the platform's attitude.
Another object of the invention is to provide a system, as described above, in which changes in platform attitude may be determined using mathematical techniques executable by a computer.
A further object of the invention is to provide a system, as described above, which may be employed to correct for perturbations in a remotely-sensed image-containing terrain data either on a near real time basis or off-line basis.
Another object of the invention is to provide a system, as described above, which is also capable of providing information relating to changes in the altitude and velocity of any airborne or orbiting platform.
A still further object of the invention is to provide a system, as described above, which is compatible for use with conventional, airborne and spaceborne sensors and is particularly lightweight and compact.
Another object of the invention is to provide a system of the type mentioned above which is capable of determining changes in the attitude of the platform in spite of the fact that a full image data set cannot be obtained within the field of view of the sensor due to partial cloud cover or the like.
These objects, in addition to other objects and uses for the invention, will manifest themselves in the ensuing description.

Referring first to FIG. 1, one aspect of the present invention broadly relates to a system for detecting and measuring the attitude changes of a platform aboard a moving vehicle such as a satellite 10 or an aircraft 12 flying or orbiting along a selected flight path 13. Any of various devices may be mounted on such platform which require precise aiming, including a sensor, a scanner or an energy beam pointer such as a laser beam reflecting mirror or a radio frequency antenna. It is to be understood here, however, that the term "platform" is used in its broadest sense to describe any structure, gimbals, or mechanisms to which the sensor, pointer, scanner, etc. is connected or upon which the same is mounted, even through such structure, gimbal or mechanism is movable with respect to the aircraft or spacecraft. For purposes of the immediately following description and for sake of simplicity it will be assumed that a sensor is mounted on the platform. Changes in platform location and attitude result in sensor orientation changes with respect to the terrain it is imaging and introduce non-systematic geometric distortions in the image terrain data. By way of example, the platform mounted sensor may consist of a panchromatic or a multispectral scanner which is employed to view terrain below the platform and generate electronic signals. These signals can be processed by a computer to create images of the terrain below the flight path 13 as the platform passes over the earth's surface. The imaging sensor has a field of view 14 which traverses the earth's surface along a swath path 16. For purposes of the present description, the imaging sensor will be referred to as the primary sensor, which may be either an optical-mechanical type or the more modern type which employs one-dimensional linear arrays, commonly referred to as a "push broom" or "multi-linear array" scanner. A panchromatic (black and white) representation of the latter type is used for illustrative purposes. In either case, the image sensor includes photosensitive detector elements arranged in a common focal plane, along with optical elements, and various types of electronic components. The orientation or attitude of the focal plane, the aim of the optics, and the sensor's altitude above the terrain determine the field of view on the earth's surface.
As shown in FIG. 2, a simplified terrain sensor may comprise a one-dimensional or linear array 20 onto which a linear strip 18 of terrain is focused by means of a lens 24. Repetitive scanning of successive strips on the earth's terrain by the linear array sensor 20, and the forward motion of the sensor's platform, result in the acquisition of a set of image data scan lines which can be processed in a computer to form an essentially composited picture of the surface traversed by the sensor's field of view.
Ideally, the sensor platform mounted on the satellite 10 or aircraft 12 will attempt to maintain a steady or linear flight path 13 at a constant velocity, attitude and altitude when the earth's surface is being scanned by the terrain image sensor 20 so that successive image scan lines are all recorded in perfect geometric relationship with respect to previously recorded scan lines. In fact, however, non-systematic changes in aircraft's 12 attitude, altitude, and velocity occur due to the effects of wind buffeting, changes in air density, and inadvertent course changes or, in the case of a satellite 10, the effects of atmospheric buffeting, orbital control maneuvers, and changes in the satellite's center of mass due to fuel consumption, antenna and solar array orientation changes, etc. These "platform changes" result in corresponding changes in the attitude of the terrain image sensor 20, which in turn introduce geometric infidelity into the image data. Geometric infidelity in the image data is extremely difficult to remove by subsequent image processing without an intimate knowledge of the frequency and magnitude of the perturbations imposed on the sensor 20. The present invention is directed toward providing a system for detecting attitude, altitude, and velocity changes in the platform. It involves recognition of the fact that changes in platform attitude can be detected and measured by comparing two, two-dimensional overlapping images of terrain acquired by a second imaging sensor instantaneously from two points along the platform's flight path.
As shown in FIG. 2, in accordance with the present invention, a second terrain image detector or sensor 22 is mounted on the same platform as the primary image sensor 20, and may consist of a commercially available two-dimensional array of photosensitive elements mounted in a common focal plane. The second sensor 22 is mounted such that its image plane is parallel to, or preferably coplanar with, that of the first linear array sensor 20. Suitable electronics (not shown) of a conventional nature are employed to electronically scan the second sensor array 22 to obtain a synoptic digital image raster (i.e. all image data in one frame is obtained from the same point of view, or instant in time, from the flight path) of all or part of the terrain scanned by the primary sensor 20. This latter-mentioned image data is used as the reference from which changes in attitude, altitude and velocity are detected and measured. As conceptually illustrated in FIG. 2, the scan area 26 scanned by the second sensor 22 through the lens 24 overlaps the scanned area of the linear array 20. Although this may be convenient from a system engineering point of view, this configuration is not a requirement as long as sensor 22 records overlapping two-dimensional images of a reference terrain.
Referring now to FIG. 3, sensor 22 is employed to record a series of overlapping images corresponding to the scan areas 26 on the ground. Each of the images or scan areas 26 is a "master" image and the succeeding image constitutes a "slave" image of the master. The time interval between recording successive images of the scan areas 26 will be determined by the velocity of the sensor platform, the total field of view of the sensor, the nominal frequency of sensor platform attitude, velocity and altitude changes, the spatial resolution of an element of the two-dimensional array 22, and the spatial resolution of an element of the linear array 20. The scan area 26 will vary in position and size in accordance with changes in the attitude, velocity and altitude of the sensor platform 12, illustrated as an aircraft. For example, the scan area 26a corresponds to a set of conditions where the sensor platform 12 is assumed to be on its proper flight path, at a constant altitude and velocity. Scan area 26c represents the area of the earth which is imaged when the sensor platform 12 undergoes a roll. Scan area 26d represents the image which is acquired when the sensor platform 12 rises above the altitude it had when it acquired its previous image. The corresponding changes of the image recorded by the terrain image sensor 20 are depicted in FIG. 1. In any event, it may be appreciated that the changes in the image recorded by the linear array 20 are directly related to the changes in the images recorded by the sensor 22 since both of these sensors 20, 22 have focal planes which are fixed relative to each other and are therefore perturbed in the identical manner by external forces.
An overview of the system will now be provided, followed by a more detailed description with reference to the drawings. A spatial displacement factor between the master and subsequent slave images is predicted from the velocity and altitude of the sensor platform 12, and is then applied as an offset to the image rasters, i.e. the sets of digital data which respectively represent the master and slave images. The master and slave images are then registered, and a minimum of three, and preferably five, pixels from the master image are tested for correlation with corresponding pixels in three or five patches of the slave image. Perfect correlation results when there are no changes in the sensor platform's velocity, attitude (when compared to nominal values assumed) or changes in attitude (yaw, roll or pitch) in that segment of the sensor platform's trajectory. In the event of less than perfect correlation, a series of geometric offsets are applied to patches of the slave image and the correlation of the master image is repeated. The collection of offsets, applied to slave image patches, which best correlate to the master image characterizes the geometry of a change from the predicted location (i.e. velocity and altitude) and attitude of the sensors 20, 22. In other words, the three or more pixels in the slave image which attained the highest correlation coefficient between the master and slave images define the orientation of the two-dimensional array of the sensor 22, and thus define the change in the location and attitude of the sensor 20, between the times that the master and slave images were recorded. It is therefore possible to define the relative temporal change of the sensor platform's location and attitude with respect to the master image data previously collected by the attitude data acquisition imaging sensor over a reference area on the terrain.
The absolute attitude of the sensors 20, 22 can best be determined if the reference area is well known on the ground. However, this absolute attitude determination is somewhat more practical for a satellite sensor platform which passes over the same earth terrain in a mater of hours or days, than for an aircraft sensor platform. In the event that the reference area on the terrain is not well known, the sensor platform's change in attitude and change from its expected location is detected by the sensor system 22 relative to the sensor platform's attitude and location over the previously recorded reference area. This is sufficient to correct the resulting images recorded by the terrain image sensor 20 for altitude, velocity and attitude variations which have occurred during the time it takes for the primary imaging sensor 20 to acquire at least two image scan lines.
Reference is now made to FIG. 4 which depicts overlapping master and slave images, respectively, designated by the letters "A" and "B". A plurality of terrain reference points on the slave image are designated by the circles 28. These same reference points are represented on the master image by the dots 30, with the arrows correlating the circles 28 with the corresponding dots 30. As shown in FIG. 4, the master and slave images, "A", "B", respectively, are depicted in the "as acquired" geometry of the overlapped part of the slave image. The amount of overlap was mathematically predetermined based on the elapsed time interval between the recording of these master and slave images and the predicted velocity and altitude of the sensor platform 12.
It is then necessary to determine the geometric orientation of the slave image relative to the master image such that the corresponding points on the terrain 28, 30 are in registration with each other, that is to say, when the terrain points 28, 30 are "correlated" and geometrically coincident. The geometric attitude of the slave image which results in coincident terrain points 28, 30 can be derived from a plurality of terrain points on the slave image. These points represent a high correlation with the same points recorded on the master image. This is accomplished by selecting at least three or preferably five spatially dispersed reference points on the slave image. Although from simple rules of geometry it is known that only three points are required to define a plane, it cannot be assumed that the terrain which contains those points to be correlated is a simple plane, or that the elevation of every point on that terrain is known. Therefore, it is normally necessary to rely upon relative orientation principles of photogrammetry that require a minimum of five points, which are identifiable in both the slave and master image (correlated), in order to define all of the variables which will solve the mathematical orientation problem in a relative sense, i.e. the slave image relative to the master image. The coplanarity condition of photogrammetry requires that for each of the five points chosen, the ray connecting the point on the ground with the camera's lens at a first point in time, and the corresponding point on the film image and the ray connecting the same ground point with the camera's lens at a second point in time with the corresponding point on the second film image, both lie in a single plane. The relative orientation operation requires that at least five pairs of rays (as found using the coplanarity condition) intersect in order that all pairs of rays in the two arrays intersect. The coplanarity condition and the equations defining same are discussed in more detail in the Manual of Photogrammetry, American Society of Photogrammetry, 4th Edition, page 55 et seq., Copyright 1944, 1952, 1966, 1980, the contents of which are incorporated by reference herein.
Referring now also to FIG. 6, five patches 34-42 from the slave image are then selected for correlation with the reference points 37 on the master image. Each of the patches 34-42 are illustrated as a 9�9 array of pixels. A correlation is then performed to determine the amount of gray scale (brightness) correlation between every pixel in patches of the slave image 34-42 with the corresponding reference point or pixel 37 in the master image. Gray scale intensity or brightness is a value which is a function of average integrated radiance on the ground point represented by a pixel. In effect, the slave image patches 34-42 are incremented in the X and Y direction (as shown in FIG. 6) so that a correlation is performed between each X, Y location in the slave image patches 34-42 and the corresponding reference point or pixel 137. This image data processing technique is sometimes referred to in the art as "neighborhood processing". The pixel in the slave image patches 34-42 having the highest correlation coefficient is then selected and its X, Y location in the pixel array or patch is recorded. The recorded locations of the pixels having the highest correlation in the slave patches 34-42 define the true locations of the slave patches 34-42, and thus of the entire slave image relative to the master image. FIG. 5 illustrates slave image "B", spatially registered relative to the master image "A" after the slave image has been geometrically "warped" in two dimensions relative to the master image such that reference points 28, 30 are coincident.
The system described above can be implemented using one relatively large, or five or more relatively small, two-dimensional solid state array(s) of photosensitive elements mounted in the same focal plane as the primary image data acquisition sensor, or a focal plane which is coplanar to it. The arrays can either be connected with a special purpose, high speed image processor which performs the image correlation process in "real time", or the image data acquired by the attitude data acquisition imaging sensor can be recorded with a synchronization signal generated by the primary sensor for "off-line" processing and geometric correction of image data acquired by the primary imaging sensor on an as needed basis. These processors are conventional in the art, consequently, their details need not be described herein. However, such a processor may consist of commercially available software such as ATOM (Automatic Topography Mapper) which was developed by and is available from GeoSpectra Corporation of Ann Arbor, Mich. The output of the processor may consist of either the location of the five or more slave image pixels correlated to the master image, or of the equation of the plane of both the master and slave images. As the sensor platform 12 continues along its flight path, the old slave image becomes the new master image, but the planes of all the slave images are traceable back to the original master image.
As shown in FIG. 7, changes in the altitude of the aircraft 12, and thus the sensor platform, are detected merely as changes in the image scale, or the distance between correlated sets of pixels on the master and slave images, with the planes of the master and slave images remaining parallel but no longer coplanar. As shown in FIG. 8, a change only in the velocity of the platform 12 (and thus of the imaging sensor) results in a different linear translation of the image planes, with both the master and slave images remaining coplanar. The master and slave images no longer remain coplanar or parallel in the event of the yaw, pitch or roll of the sensor platform. The non-coplanar condition of the master and slave image planes caused by a simple change in platform and sensor pitch is illustrated in FIG. 9.
A logic flow chart for a typical computer program which implements the system described above is depicted in FIGS. 10-13. Referring to FIG. 10, the first step 44 in the program consists of successive locations along the flight path in order to acquire the master and slave image data. Then, image correlation is performed in patches of the overlapping master and slave image region in order to identify correlated match points in that area of the terrain which is imaged twice. The second step 46 consists of determining the relative orientation of the slave image plane with respect to the master image plane using the principles of relative orientation from photogrammetry mentioned above, which require a minimum of five correlated match points located in both the master and slave images. The sub-routine for performing step 44 is shown in FIGS. 11 and 12. The first step of the sub-routine at 48 consists of applying the same offset derived from the previous master/slave image correlation procedure, or an estimate based upon the nominal platform velocity multiplied by the image sensor sampling interval. The overlapping area is then segmented into at least five or more patches at 50 if a relatively large, two-dimensional imaging array is employed as the attitude sensor, or the five or more terrain image patches are acquired by five or more relatively small two-dimensional area arrays as described above. A two-dimensional correlation search is then performed in each master and slave image data patch at 52. The correlation step 52 is performed by having a computer select the match candidate area in the master image which has the highest contrast edge and/or point in one two-dimensional image at 54 of FIG. 12. An analogous equivalent procedure for visual inspection would be the selection of a distinct set of pixels. At step 56, if the matched candidate in the master image does not have a suitably high correlation peak in the slave image, additional candidates are processed, otherwise control is transferred to step 52.
The sub-routine for performing step 46 (FIG. 10) is shown in FIG. 13. An estimate of the orientation parameters is initially made at step 58, followed by a mathematical step performed at 60 consisting of minimizing the squares of deviation from the ideal condition of master and slave image coplanarity for five or more paris of correlated points. A determination is made at 62 as to whether the deviations are less than a threshold value (determined by the geometric precision required of the image data acquired by the primary imaging sensor). If the deviations are less than the threshold, step 60 is repeated. Otherwise, the sub-routine is terminated. The output product of this process is the collection of equations which describe successive focal planes, hence the locations and attitudes of the primary imaging sensor and its platform. These equations will enable precise geometric corrections of image data acquired by the primary sensor, either in a relative sense with respect to image data previously recorded on that "flight" segment, or in an absolute sense with respect to a map of the terrain. The latter case requires an image data base of uniquely identifiable areas on the terrain, including their map coordinates and elevations, which can be used to orient a master or slave image with respect to the terrain, using the above-described correlation and coplanarity test methodologies.
Again, while one aspect of the invention has been described above in connection with a scanning type sensor undergoing perturbations, it is to be emphasized that the present invention is equally applicable where certain other kinds of devices are mounted on the platform, such as an energy beam pointing device, e.g. a reflector or antenna. The reflector or antenna may function to direct an energy beam to a target either on the ground or to another aircraft or spacecraft. The functional requirements for a platform attitude or altitude data acquisition system used to geometrically control image data acquired by the primary terrain imaging sensor on the platform, and one used to precisely control the pointing of a beam of energy from the same platform are identical, with the exception that the latter application necessitates the output data being employed to dynamically control the beam pointing mechanism rather to correct image data. Thus, the acquired set of attitude and altitude data is used to adjust the reflector or antenna; this may be accomplished by sending signals to the mechanism, typically servomotors, used to change the orientation of the reflector or antenna or alternatively for example (in the case of a satellite) to fire thruster jets which correct the satellite's attitude so that the reflector or antenna is properly positioned. The details of controlling the reflector or antenna in this manner using the acquired information regarding attitude and altitude are well known in the art and therefore need not be discussed here.
Another aspect of the method of the present invention will now be discussed with reference to FIG. 14 which is similar in many respects to FIG. 1, and shows an aircraft 12 moving along a desired flight path, although it is to be understood that the following description is equally applicable to a satellite or other spacecraft. The aircraft 12 is equipped with a platform of the type mentioned above on which there is mounted a terrain imaging sensor which may comprise a two-dimensional array, of the type designated by the numeral 22 in FIG. 2, as well as the reflector or energy beam pointer. As shown in FIG. 14, an energy beam 64 is directed to the reflector or antenna mounted on a platform carried by the airplane 12 which then precisely points the beam in the direction indicated by the numeral 66. As mentioned above, the energy beam 64 may originate either from a ground station or another aircraft or spacecraft and, likewise, the reflected beam 66 may be directed to another aircraft or spacecraft, or alternatively to the ground. Also, the outgoing beam of energy 66 may be generated at the aircraft 12, in the case of a radio transmission, for example.
In any event, the two-dimensional sensor array records successive, overlapping sets of image data as the aircraft 12 moves along its path of flight and the novel method described above is performed in order to determine changes in the altitude and attitude of the aircraft 12, and thus of the platform and reflector or beam pointer. For purposes of illustration, in FIG. 14, successive scans 18 are indicated along the swath path 16 including several formed during a roll of the aircraft 12, indicated at 74 and during changes in altitude shown at 72.
The data regarding changes in attitude and altitude mentioned above is generated on a real time basis and is employed by an on board control system, typically including a preprogrammed computer, to dynamically control the attitudes of the reflector or antenna. Typically, such control will be effected by sending control signals to servomotors or the like which control the mechanism which moves the mounting platform in order to precisely redirect the outgoing energy beam. The calculation of changes in attitude and altitude, and the subsequent repointing of the reflector or antenna are carried out substantially at the same time so that repointing is performed as quickly as possible after a change in attitude or altitude has been detected.
It often occurs that the ground below the image sensor or beam pointing platform, within the field of view of the two-dimensional imaging array, is not visible due to cloud cover indicated by the number 68 or the presence of a body of water indicated at 70. For example, at the position of the aircraft 12 indicated in FIG. 14, the imaging array is scanning across a path indicated at 76 in which the terrain is partially obscured by a lake 70 and clouds 68. Note that the width of the field of scan 76 by the primary sensor is considerably wider than that of the two-dimensional sensor array, designated by the numeral 78. Such presence of clouds or bodies of ground water which obscure the field of view of the secondary, two-dimensional array sensor ordinarily preclude measurement of changes in the platform attitude and altitude. As a result, the data acquired by the much wider field of the primary imaging sensor must be discarded due to poor quality for many applications including mapping because such data cannot be corrected for attitude and altitude, even through the primary sensor records mapping data that is otherwise valuable for mapping purposes. In the case of applications for energy beam reflection or pointing, the limitation described above is even more critical since the conditions (clouds, water) directly below the aircraft (and thus the two-dimensional imaging array) are likely to be inconsequential to its mission. In other words, the nature of the ground immediately below the aircraft normally has no affect or relationship to the direction and destination of the beam of energy to be reflected or directed by the aircraft 12.
Even when the two-dimensional sensor array is recording image data where clouds or water partially cover or obscure its field of view, its output data regarding attitude and altitude changes cannot be relied upon with a high-level of confidence for two reasons. First, the image detail and/or contrast may be insufficient to achieve successful point correlations between successive images. Secondly, the ground surface being imaged is not stable; in other words, the ground surface may not have discernible features and/or is moving such that its appearance changes between two successive "looks" by the two-dimensional array sensor. In order to overcome this limitation, it has been discovered that the location of the obscuring clouds or ground water can be determined in advance and a means is provided for pointing the sensor 22 to a location which is not so obscured, so that meaningful attitude and altitude change data can be generated even though obscuring clouds or ground water are located beneath the aircraft 12, where the sensor 22 would otherwise record image data that would not yield changes in the attitude and altitude.
Referring now also to FIG. 15, the aircraft 12 includes a reflective mirror 84 which is mounted on a mechanism of a conventional type (not shown) well known in the art which allows it to be pointed in a desired direction. The mirror 84 is also positioned such that it may reflect to the sensor 22 a two-dimensional image on the ground at a location determined by the pointing of the mirror 84. The mirror is pointed in the desired direction by means of a conventional deflector mechanism which can include, by way of example, conventional servomechanisms (not shown). The deflector mechanism 82 and thus the mirror 84 are controlled by a forward-looking image multispectral sensor (FLIMS), which is a conventional device well known in the art which records images in multiple spectral bands, and is thus capable of distinguishing regions on the earth from clouds, open water or other featureless regions for which the image data would otherwise be uncorrelatable. The FLIMS 80 scans a large field of view traverse to the path of the aircraft 12, and ahead of the region on the earth to be imaged by the sensor 22. The multispectral image data collected by FLIMS 80 as a result of scanning forward traverse regions 86 on the earth is delivered to an on board image processing computer (IPC) for analysis. The IPC 90 includes one or more conventional, automatic feature recognition algorithms which determine the nature of the surface imaged by FLIMS 80 and thus knows in advance whether there exist any areas on the earth where the sensor 22 may be pointed in order to record meaningful ground images. The sensor 22 thus delivers image data to the IPC 90 and the IPC 90 determines whether the image being viewed by sensor 22 includes cloud cover, ground water or other featureless images, and in such an event controls the deflector mechanism 82 so as to train the sensor 22 on an alternate region of the earth 78a which is transverse to the normal field 88 scanned by the primary sensor (FIG. 2). Thus, the sensor 22 is directed to view the ground areas most favorable to generating useful, correlatable two-dimensional images and thus assures that useful attitude and altitude data may be collected.
Having thus described the invention, it is recognized that those skilled in the art may make various modifications or additions to the preferred embodiment chosen to illustrate the invention without departing from the spirit and scope of the present contribution to the art. Accordingly, it is to be understood that the protection sought and to be afforded hereby should be deemed to extend to the subject matter claimed and all equivalents thereof fairly within the scope of the invention.

Recent reviews

Everything was very nice and comfortable
This is a terrible choice for a hotel room when looking near the Milwaukee airport. So many better hotels, and motels for that matter. This place should be rated with 1 star at best. Dirty room, no cable TV (offered a lame excuse and was told it would be fixed, came back after 8 hours of meetings, not fixed), no housekeeping (my food from the night before was still in my room after I returned, bed not made, towels not replaced)no wake-up call (it must not be working right today I was told). Al wall AC unit, just like an old motel. Loud as can be. Wow! Please avoid this place at all costs.
Everything was great except the cable did not work and was not told this prior to check in. Other than that it was good for the 2 day stay.
I was disappointed about the TV not working right, but I did not take the time to call the front office to see if they could fix it. It was too late. I was also disappointed about the temperature of the water when I took a shower. I was happy with the location and the bed was very comfortable.
This hotel would not honor their free airport parking with stay because we booked through Hotels.com Parking was filled with seagulls, which in turn left the deposits on vehicles.

Carl Macek didn't do the older dub of Laputa; it was done by an independent company very quickly and very fast, and as such, it is pretty terrible. (Trust me, I can only listen to about as much as 30 seconds of it.) Disney's version of this movie has some minor faults but is a much better dub overall. Plus, you can't go wrong with Mark Hamill as the badguy.
Kiki's older dub is good and roughly about on par with Totoro's older dub, but I personally like Disney's version better.

I still would've wanted younger voices for the two kids anyway.[/quote]
Yes the leads DO sound considerably older than they probably should in Disney's dub, but even that grew on me the more I watched it. The older dub uses Barbara Goodson and Lara Cody to play Pazu and Sheeta, and sadly, their performances are completely underwhelming. Oh sure, they don't sound as mature, but I found Barbara and Lara to be both devoid of any genuine emotion and artificial sounding--there was an obvious feminine quality to Barbara's Pazu that I found particularly distracting and Lara's Sheeta was so shrilly that it quickly turned me off. Even any so called moments of "emoting" are not as strong as they should be.
While James and Anna probably were somewhat eccentric choices for these characters (not so for the latter, as she still does sound a bit childlike), I found that both did considerably better jobs overall. Granted, they ARE the least excellent voices of the dub compared to Hamill and Leachman (as well as everybody else--those guys are what REALLY make the dub so much fun), but at least they put more emotion and energy into their performances aside from a missed line or two.
The supporting cast in Streamline's dub are absolutely HORRIBLE compared to Disney's; Jeff Winkless's Muska is especially dreadful--so dull and monotonous, with absolutely zero emotion or charisma; every second of his performance is totally devoid of any genuine dread or creepiness. Mark Hamill is far better, both vocally and in terms of acting; granted he does sound like the Joker at times, but there really is no comparison over who does Muska better--Mark Hamill owns him from the start. Rachel Vanowyn's Dola either screams with no personality or comes across as a very stilted and emotionally flat--Cloris Leachman is a far better Dola. And likewise, all the minor characters sound a lot more livelier in Disney's dub; their Streamline counterparts are just lame (well, except for the General, but even then I liked Jim Cummings better).
It wasn't just the voices that turned me off from this older dub so much; the writing of the script is not very good at all, with inept-sounding or very bizarre lines that made me either cringe or groan. Oh sure, it DOES keep the last part of Sheeta's speech (which is something that Disney's version doesn't do), but that simply isn't enough to make up for the stale writing ("I'm built as hard as a brick moppet" and "Now say bye-bye!" in particular are embarrassments). While Disney's script probably does go overboard in adding in dialogue to certain scenes and omits both the last part of Sheeta's speech as well as the references to "Gulliver's Travels" and "Treasure Island", it is overall much more smoother sounding and never sounds choppy or stale.
There may be some fans who say this older dub surpasses Disney's, but I was very disappointed with it; I have never heard such a dull, shrilly, lifeless dub in such a long time since the old '80s Akira dub. If anything, it only showed me how far dubbing has come since the '80s. So Disney's version is the better dub for Castle in the Sky overall; it's not perfect by any means, but it's still grossly underrated and certainly deserving of a second look.

This is why I stopped caring of what other people think (and besides, Streamline didn't work on Laputa anyway).

Yeah, well, the reason why Carl Macek wasn't so happy with how Streamline's dub turned out was because he didn't do it. They simply picked it up from an unknown company. (Hence why he made the older dubs for TOTORO and KIKI; he wanted to show he could do better.) Nonetheless I will tell you that I have absolutely nothing against the actors in any of these dubs. But for this older dub, I will say that Goodson, Cody, Winkless, etc. all have done far better. While Disney's version probably does go overboard in adding in dialogue in places and has the leads as teenagers, it's still a lot more pleasant to listen to; at least nobody in the dub sounds like they're talking like a robot. (Certainly not Hamill or Leachman, or frankly, the rest of the cast for that matter.)
But seriously, yeah, it baffles me how ANYBODY can say the Disney dubs are inferior, not just for this movie, but for ANY of the Ghibli movies, period. Not that there haven't been good dubs, but it's really hard to get any better than these. Plus, since Miyazaki virtually has no issues with any of them, it seems curious to hear some so-called "fans" declare that they compromise his work.
That's why I choose to evaluate the Disney dubs on their own turf, not as comparison tools to the Japanese; and I've taken that view with ANY dub I listen to. And I've never regretted it.
