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
