Abstract
This article describes an implementation of the optical flow estimation 
method introduced by Zach, Pock and Bischof in 2007. This method is 
based on the minimization of a functional containing a data term using 
the L1 norm and a regularization term using the total variation of the 
flow. The main feature of this formulation is that it allows 
discontinuities in the flow field, while being more robust to noise than 
the classical approach of Horn and Schunck. The algorithm is an 
efficient numerical scheme, which solves a relaxed version of the 
problem by alternate minimization.
