From attached picture, you can see the difference between frame (h8.png) that contain on white area and frame h4.png is 4 frames and difference between h13.png & h8.png is 5 frames, the difference between h26.png & h13.png is 13 frames and the difference between h29.png & h26.png is 3 frames. How can I write code to calculate differences between frames that contain on white areas.

在 MATLAB Online 中打开

ExtractMovieFrames.m

I think I already gave you code to do video processing (attached again just in case). So you just keep track, in the frame index loop, which frame have white blobs in them. Then just use the diff() function:

frameDifferences = diff(framesWithWhiteBlobs);

@Mehmed Ozkan go ahead. If you need a citation, just use the URL for this conversation. More movie demos are attached to give you more smiles.

Excuse me for the late response Image Analyst, it gave me so many smiles and sent me down so many new rabbit holes. Learned a lot! Thank you
