I have been trying to do some homography estimation between different frames in a video using Lucas Kanade Optical Flow Tracking (yes, I have already taken a look at the opencv sample). I have written up some code and tested it to see if I could start out by just tracking points in some videos I took. In every video, the points start out fine, and are tracked well for a few frames. Then, all of a sudden, the following happens:
This happens about 10 frames in after the points seem to be tracked just fine. Similar results occur in all of the other videos I have tested. Why is this happening and how can I fix it?
