Lucas Kanade Method (matlab)
This code includes the basic Lucas Kanade algorithm and Hierarchical LK using pyramids. Please refer to the 'readme' file included in the package for help on using the code. Following is a test sample to demonstrate the use of this code to calculate the optical flow.

Code from Piotr Dollar (matlab)
It provides three methods to calculate optical flow: Lucas Kanade, Horn & Schunck and cross-correlation.

Brox and Sand Methods (matlab)
This code implements a variation of the paper "High accuracy optical flow using a theory for warping", presented at ECCV 2004. Details of implementation, especially the numerics, have been adapted from the PhD thesis of Dr. Thomas Brox. Extension to different color channels, and the concept of a local smoothing function, has been adopted from the PhD thesis of Dr. Peter Sand.
