Optical flow using the Proesmans method
Optical flow calculation using the gradient-based method devised by Marc Proesmans. Look at the beginning of the cpp file for instructions on how to compile and call the proesmans function from MATLAB®.
The algorithm is described and used in a couple of journal papers, look in the cpp file to find out more.
Incidentally, this also works as a good example on how to call c and cpp files from MATLAB.
Note that this has been tested mostly with Microsoft Visual C++ compilers, it's not guaranteed to work with other compilers.
