Zdenek Kalal has come up with a system that can quickly learn how to track objects in a video stream. The demo is quite interesting. The related papers are mentioned at the end of the video (and also on Zdenek's website). To decide if the tracking algorithm is actually so robust or not, I'll have to go through the papers. But for now, the video is quite impressive. Oh, by the way, this isn't an april fool's video ;)
