Now i know that the coordinate system is messed up. I have tried reversing the view and imageView, nothing. I then tried to reverse the coordinates on the features and i still get the same problem. I know it detects the faces, eyes and mouth, but when i try to place the overlaying boxes from the samples codes, they are out of position (to be exact, they are on the right off-screen). Im stumped as to why this is happening. 

Ill post some code because i know some of you guys like the specificity: 

```
-(void)faceDetector
{
    // Load the picture for face detection
//    UIImageView* image = [[UIImageView alloc] initWithImage:mainImage];
    [self.imageView setImage:mainImage];
    [self.imageView setUserInteractionEnabled:YES];

    // Draw the face detection image
//    [self.view addSubview:self.imageView];

    // Execute the method used to markFaces in background
//    [self performSelectorInBackground:@selector(markFaces:) withObject:self.imageView];

    // flip image on y-axis to match coordinate system used by core image
//    [self.imageView setTransform:CGAffineTransformMakeScale(1, -1)];

    // flip the entire window to make everything right side up
//    [self.view setTransform:CGAffineTransformMakeScale(1, -1)];

//    [toolbar setTransform:CGAffineTransformMakeScale(1, -1)];
    [toolbar setFrame:CGRectMake(0, 0, 320, 44)];

    // Execute the method used to markFaces in background
    [self performSelectorInBackground:@selector(markFaces:) withObject:_imageView];
//    [self markFaces:self.imageView];
}

-(void)markFaces:(UIImageView *)facePicture
{
    // draw a CI image with the previously loaded face detection picture
    CIImage* image = [CIImage imageWithCGImage:facePicture.image.CGImage];

    // create a face detector - since speed is not an issue we'll use a high accuracy
    // detector
    CIDetector* detector = [CIDetector detectorOfType:CIDetectorTypeFace
                                              context:nil options:[NSDictionary dictionaryWithObject:CIDetectorAccuracyHigh forKey:CIDetectorAccuracy]];

//    CGAffineTransform transform = CGAffineTransformMakeScale(1, -1);
    CGAffineTransform transform = CGAffineTransformMakeScale(self.view.frame.size.width/mainImage.size.width, -self.view.frame.size.height/mainImage.size.height);
    transform = CGAffineTransformTranslate(transform, 0, -self.imageView.bounds.size.height);

    // create an array containing all the detected faces from the detector
    NSDictionary* imageOptions = [NSDictionary dictionaryWithObject:[NSNumber numberWithInt:6] forKey:CIDetectorImageOrientation];
    NSArray* features = [detector featuresInImage:image options:imageOptions];
//    NSArray* features = [detector featuresInImage:image];

    NSLog(@"Marking Faces: Count: %d", [features count]);

    // we'll iterate through every detected face.  CIFaceFeature provides us
    // with the width for the entire face, and the coordinates of each eye
    // and the mouth if detected.  Also provided are BOOL's for the eye's and
    // mouth so we can check if they already exist.
    for(CIFaceFeature* faceFeature in features)
    {

        // create a UIView using the bounds of the face
//        UIView* faceView = [[UIView alloc] initWithFrame:faceFeature.bounds];
        CGRect faceRect = CGRectApplyAffineTransform(faceFeature.bounds, transform);

        // get the width of the face
//        CGFloat faceWidth = faceFeature.bounds.size.width;
        CGFloat faceWidth = faceRect.size.width;

        // create a UIView using the bounds of the face
        UIView *faceView = [[UIView alloc] initWithFrame:faceRect];

        // add a border around the newly created UIView
        faceView.layer.borderWidth = 1;
        faceView.layer.borderColor = [[UIColor redColor] CGColor];

        // add the new view to create a box around the face
        [self.imageView addSubview:faceView];

        if(faceFeature.hasLeftEyePosition)
        {

            // set the position of the leftEyeView based on the face

            // round the corners
            leftEyeView.layer.cornerRadius = faceWidth*0.15;

I know the code segment is a little long but thats the main gist of it. They only other thing relevant to this is that I have a UIImagePickerController that gives the user the option to pick an existing image or take a new one. Then the image is set into the UIImageView of the screen to be displayed along with the various boxes and circles but no luck to show them :/

Any help would be appreciated. Thank~

Update:

Ive added a photo of what it does now so you guys can have an idea, ive applied the new scaling which works a little better but nowhere near what i want it to do.
