Possible configurations of CR-HOG regarding the number of orientation bins. The range of gradient orientation angles [0-180) is divided in uniformly spaced sectors. Pixels with gradient orientations inside each sector accumulate to the corresponding bin of the histogram proportionally to the magnitude of their gradient. Configurations with (a) 8, (b) 12, and (c) 18 bins are considered.
