dense realtime optical flow

Holy crap! are you kidding me?! This is a realtime computation of dense optical flow, and even though the image is fairly low, I can’t believe they are able to do it at all.  The color encodes the direction of moving pixels, and intensity their speed. Implemented using CUDA, running on a single GeForce 8800 GTX. Visit gpuvision for more videos and binaries.
