How do I perform background subtraction for video input from my web cam? I know how to do this for images and video files, but not for real time video.

Hi David, can I know the code for background substraction for the image and the video files?

nabihaa, my code in my answer gives code to subtract an image (generated from the average of some prior frames) from the current frame. Of course you could adapt it to subtract a constant, fixed image that you read from disk if you want. That should be trivial.

This is done in my demo, attached below. You just need to adapt it to call getsnapshot instead of read() so that it get image from your webcam rather than a video file.

Hello Sir. Can I get the description for this code, so that it will be easy to understand?

I'm attaching the latest version. I think it's pretty well commented. Again, it's for a video but you need to change read() to getsnapshot() or whatever the command for a web cam is if you want to do it in real time rather than from a pre-recorded video.

You could get the frames from each video and apply your algorithm on each one. Is speed the issue here?
