Preliminary Results INPUT OUTPUT

Approach Input Video Clip Separate Individual Frames & Find Background Separate Foreground from Background in each Frame Filter Out Points With Threshold Imdilate Points To Improve Picture Overlay Each Foreground On Background To Create Individual Frame Combine Frames Into Video Clip

Matlab Stuff Frame - Background BWareaopen Imdilate

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.

Panoramic Video Camera 1 Camera 2 Usually on TV they just switch camera angles...now wouldn't it be cool if we had the whole view? New Video
