I guess you should use original X1,Y1 instead of computed xt,yt for the calculation of Ix Iy I1 in each higher pyramid.

Nice! This works well for my cell tracking application.

If you want to learn more about the method, take a look at the lecture that this code is based on:

Hi Edward,
could you tell me what literature you used for this algorithm?
Was it by any chance:
1. Pyramidal Implementation of the Lucas Kanade Feature Tracker
Description of the algorithm?

Hi Edward,

How do you use your algorithm?
Is there any demo?

I'm able to see what to do with X2 and Y2?

Best Regards
