cvCalcOpticalFlowFarneback: where to find the code [closed]
I am new here. I am looking for the code that implements the Gunner Farneback's algorithm for motion estimation between subsequent frames of a movie (namely cvCalcOpticalFlowFarneback). I have found examples on how to use cvCalcOpticalFlowFarneback, but I am not able to find the code itself. Does anybody know how I can find it? Thank you very much
