Following the balls

To understand the problems MultiModal Painter (MMP) senior students are facing I decided to apply some of my computer vision skills trying to solve one of them. To that end I implemented a small program that follows a set of balls in a pre-recorded video. Using MATLAB 6.5, it took me only a few lines of code to achieve it. The resulting video is available for download (ZIP [148KB]).
