The following is an implementation of a basic Lucas-Kanade Feature Tracker

Tracking a German van
In the following example, I downloaded an mpeg movie from
http://i21www.ira.uka.de/image_sequences/
and used the function, mpgread from
http://www.win.tue.nl/~haas/matlab/mpeg-jes/mpgread/
to decompose and track a van over about 80 frames of video

Lk_van.avi

Matlab files
These may be changed some to fix the van avifile problem
