I learned that there is several method for optical flow extraction.I want to know what' your principle.Is there a paper for this?

This tool uses Brox algorithm. As you can see at the beginning of the compute.cpp file. // compute_flow.cpp // Computes OpenCV GPU Brox et al. [1] and Zach et al. [2] TVL1 Optical Flow .

@blgnksy Hi,I see this cpp refers to two references: [1] T. Brox, A. Bruhn, N. Papenberg, J. Weickert. High accuracy optical flow estimation based on a theory for warping. ECCV 2004. [2] C. Zach, T. Pock, H. Bischof: A duality based approach for realtime TV-L 1 optical flow. DAGM 2007. So the algorithm used in compute_flow.cpp is the combination of two methods or just brox algorithm?? Coz I couldn't configurate the environment well,i just want to find some substitute but if it is being modified,i only need to fix the incompatibily issue... Thanks~~
