Hi,

Can you please explain what are those NAN values in the background_frame2 matrix? I need to know which pixels are fixed among all video frames. thanks

I need to extract the background for each frame in the video. Can you please explain a bit about the background_frame2 matrix? I think that's background of the whole video. Therefore, by subtracting it from each frame I can get the motion parts. what about background of each frame?How can I get the background pixels index? Thank you.
