Optical flow for feature tracking

[weisongwen]

hi @uba , Thanks for sharing such a nice work. Could you kindly provide some suggestions if I want to track two features in two images based on your code?

Currently, I want to test the feature tracking using optical flow. In other words, I would like to achieve the function as the function "calcOpticalFlowPyrLK", but I do want to use the calcOpticalFlowPyrLK function directly from the OpenCV library.

Thanks a lot in advance,

Best,
Weisong,
