Hi all,
Having a set of frame, I want to detect which object is in movement. I don't need nothing more than a mask that for each frame is positive just for that object. I also believe that it will be fine to detect it between 2 frames and I also don't need small objects in movement, but just one that are significantly noticeable.
There is a quick way to do this ?
Thank you very much

See my demo, attached below in blue, where I calculate the difference between a frame and the average of N prior frames. Adapt it as needed.

Well I'm not searching things that general. All my images are grayscale, also is a specific case I've an object which colour is fairly different from background and it's moving one frame to another. I've got few of this situation, but let's say for example a guy walking down a road and the background is usually bright. Note that thresholding is not working as also other sparse element have such color.

Well that's all I have for you: my demo and a link to the CVS Toolbox. So good luck.
