Optical flow renderings is my final project in 6.866, Machine Vision. I implemented in Java an algorithm for calculating optical flow data designed by Professor B.K. Horn .
Optical flow is a measure of the apparent flow of brightness in a sequence of images.
A flow vector is calculated at points between pixels and between frames of a movie clip. I then used this data to create artistic renderings of the movie. I had hoped that the renderings I designed would be clearer, but it did not turn out that optical flow leads to very visually coherent results. They are still interesting to look at though, and provide a clear understanding of the results of the optical flow algorithm. The algorithm is iterative, very slow, and takes up lots of memory.
