Nick Hirsch: Progress Report
Track Features (KLT) Determine Direction of Tracked Points Compare Tracks to FoE Direction Field Update FoE Stabilize Tracks Weed Out Stationary Tracks Rate Remaining Tracks Cluster Tracks
Integrated SIFT code into codebase ◦ Tested track quality with SIFT features as opposed to KLT features. ◦ SIFT features produce slightly worse results, especially for pixels with little to no motion. ◦ SIFT also takes too long to calculate. ◦ Scrapped SIFT altogether Returned to using KLT feature points for tracking Fixed some errors with the mean shift code Tweaked KLT code to reduce noise in the tracks.
Tracks weren’t accurate enough for pixels off in the distance.
Add registration code to remove global movements due to camera shake (robustify) ◦ 75% complete ◦ Current code accounts for translation of the projection plane, but not rotation Works some of the time but not all the time Add object tracking code to remember moving objects over time
