video processing

software

1. frame by frame motion detection (FD)

2. background substraction (BD)

3. with some noise threathhold

0.1*FD + 0.9* BD  = GD

dilate -fix holes..

erode -cut the outline

4. contour finder

hardware

projector projects no infrared light. nor fluorescent lights.  therefore, by using exposed b+w film as filter on monochromic camera, we can avoid feedback problem of projected image.

BNC connector + mechanical convertar ->  RCA connector -> computer

super circuit camera connector + clamp to mount it anywhere
