CodeProject: Motion Detection Algorithms. Free source code and programming help

One of the most common approaches is to compare the current frame with the previous one. It's useful in video compression when you need to estimate changes and to write only the changes, not the whole frame. But it is not the best one for motion detection applications. So, let me describe the idea more closely. Assume that we have an original 24 bpp RGB image called current frame (image), a grays
