Algorithms for tracking objects. optical flow?

Question

Algorithms

Hello Khabrovites.
Has anyone implemented object tracking algorithms, such as the Lucas-Kanade or
Shi-Tomasi algorithm? Respond please, thirst for communication.
Big problems with the implementation of the Shi-Tomasi algorithm. Its pyramidal version, similar to the LK algorithm, is not clear - maybe someone has something?

Answer 1

Here is Lucas-Kanade's GPU implementation. raw give download.
