Modified Lucas-Kanade algorithm to detect and track cars
cabrillo1.asf is the movie of cars to track
lk_track2.py is the modified Lucas-Kanade algorithm to track cars, features are detected using the Harris corner detection algorithm. The output is all the position and instantaneous velocity of features, as cabrillo-1-lk.txt
lk-linker_2 links the positions of cars plus instantaneous velocity to nearest positions in adjacent times through k-d-tree in order to build 'IDs' of cars. Output is cabrillo-1-lk-tracked.txt
lk-track-traj visualizes cabrillo-1-lk-tracked.txt to confirm tracking
Here's an example:
