Observations

• Had to play with thresholds depending on
  background and foreground object. 15-20 seemed
  to work best for difference.
• For Bwareaopen, 4 seemed to be sufficient.
• For imdilate, I used 5 to get enough coverage
  area.
• I used every 5th frame to make the matlab
  processing run in a reasonable time.

Usually on TV they just switch camera
angles...now wouldn't it be cool if we had the
whole view?
