Hello Everyone,
I am trying to use image subtraction for extracting contours from the video. I just need to subtract the average of the first 20 frames for this particular problem. However, I figured out that current algos substract on a rolling image basis.
My current approach is: 1. Adding first 20 frames and then dividing by 20 to get average of the background 2. Substracting the averaged image from frames >20.
Is there any other way ?
Any help would be greatily appreciated ?
