Thank you, Guanta. I'm sticking with solution 1. It seems to work nicely. I'm now just naivly copying the intitial 2D locations properties to the tracked points.

Hi,

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.

Thanks
