title: image/video processing options
body: <p>I have a small 12 volt board camera that is placed inside a bee hive. It is lit with infrared LEDs (bees can't see infrared).  It sends a simple NTSC signal along a wire to a little TV monitor I have.   This allows me to see the inside of the hive, without disturbing the bees.  </p>
  
  <p>The queen has a dot on her back such that it is very obvious when she's in the frame.   </p>
  
  <p>I would like to have something processing the signal such that it registers when the queen is in the frame.  This doesn't have to be a very accurate count.  Instead of processing the video, it would be just as fine to take an image every 10 seconds and see if there is a certain amount of brightness (indicating that the queen is in frame).  </p>
  
  <p>This is useful since it helps bee keepers know if the queen is alive (if she didn't appear for a number of days it could mean something is wrong).</p>
  
  <p>I would love to hear suggestions for inexpensive ways of processing this video, especially with low power consumption. Raspberry pi?  Arduino? </p>
