how to detect and capture scene change in a recorded video I have a project to detect and capture scene change in a recorded video.Actually its a recorded video of a godown (of about 2 weeks) and I have to detect and capture pic whenever someone comes in.

I have tried vlc player motion detector. It detects changes very well but does not capture the detected scenes.
Is there any way that can help?

thanks and regards
You may use Low Rank Models for Video Background Subtraction  as a pre processing.
Once you leave out the background even simple methods will do to discern any motion.
