Optical flow functions in OpenCV

Optical flow is one method for target tracking, especially when the movement is not huge. I haven't given eyes on these papers yet. Actually, Co-Ad wanted it long time ago. The functions from OpenCV use several methods:
CalcOpticalFlowHS(), CalcOpticalFlowLK(), CalcOpticalFlowBM(), CalcOpticalFlowPyrLK(). They are mature technologies and were published 20 years ago. They may appear in some computer vision books.
