Is it possible to generate key points from points tracked optical flow?


I'm wondering if it is possible to generate KeyPoints from the 2D location tracked by a optical flow algorithm, such as calcOpticalFlowPyrLK?

I would like to eventually extract features at the 2D location of the tracked points, by they are merely 2D points and not KeyPoints, and therefor not suitable for OpenCV's DescriptorExtractor.

I could, of course, just initialize the KeyPoints from the 2D locations, but then I cannot initialize them with values. such as angle, size etc., which would influence the quality of the features.
