Description

The window size parameter in C++ calcOpticalFlowPyrLK is taken as the whole window size and divided by two to get the half window size while in cvCalcOpticalFlowPyrLK it is taken as the half window size and multiplied by two. The other pyramid optical flow algorithms do the same thing as cvCalcOpticalFlowPyrLK so only the calcOpticalFlowPyrLK code is different. If this is intended to match then they don't match and performance would vary. So is this a documentation issue or a bug that needs to be fixed in order to bring them both into agreement?
