How can I do knnMatch in a small window

asked 2014-12-24 21:29:51 -0600

I hope to do knnMatch in a small Window instead of the whole image.

For example, if I know the picture is up side down, I can just match the keypoint in the bottom part, but not the whole image.

How can I do knnMatch in this way?
