The Quicktime files below are intended to document the performance of our point tracking algorithm. We apologize for the large size of the files. Unfortunately, evaluation of the technique requires high fidelity streams of reasonable length. As such we have been unable to take advantage of high compression schemes that would introduce artifacts or otherwise compromise the fidelity of the video capture.

This dataset consists of a plane textured with VERY high resolution salt and pepper noise. It demonstrates the effectiveness of the point tracking technique in conveying a sense of motion. The camera first rotates and then zooms in. Note that the direction of motion is completely lost in the other techniques.
