Invisble Hand

See the full demo (2MB zip of jpegs): adamsmith.as/typ0/ihdemo.zip

 

Key:

- The bottom left image is read directly from the camera (a crappy webcam taped to the wall in my case).

- The bottom right image is the blurred version of the first image.

- The top right image is the blurred version of the background image from last frame (not shown).

- The bottom middle image is the absolute color difference between the two blurred images

- The top middle is a thresholded version of the difference image.

- The top left is the old background image with areas not occluded by foreground objects copied from the freshly captured image below.
