Sample the image in intervals of 8 pixels in each dimension as "dummy keypoints", and describe each 16 pixel patch with a Histogram of Oriented Gradients.

As performed in this paper:

Can be implemented with OpenCV or with skimage.

Actually, I think HOG is in skimage but not OpenCV.

Correct me if I'm wrong, Dragos.
