Dense Grid of HOG keypoints #96

Open scottclowe opened 9 years ago

scottclowe commented 9 years ago

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: http://web.engr.oregonstate.edu/~tgd/publications/WACV2011-stacked-spatial-pyramid.pdf

Can be implemented with OpenCV or with skimage.

Actually, I think HOG is in skimage but not OpenCV. http://scikit-image.org/docs/0.10.x/api/skimage.feature.html#hog

Correct me if I'm wrong, Dragos.
