2013-03-20 02:02:18 -0600	commented answer	Is it possible to generate key points from points tracked optical flow? 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.

2013-03-19 07:37:53 -0600	asked a question	Is it possible to generate key points from points tracked optical flow? Hi, I'm wondering if it is possible to generate `KeyPoint`s 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 `KeyPoint`s, and therefor not suitable for OpenCV's `DescriptorExtractor`. I could, of course, just initialize the `KeyPoint`s 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
