Fig. 4From: Segmental HOG: new descriptor for glomerulus detection in kidney microscopy imageRectangular HOG and Segmental HOG. R-HOG has been used for object detection in many applications. R-HOG is the concatenation of statistics in each block in a grid that divides a rectangular region (a) and (b). On the other hand, the blocks of the proposed descriptor, S-HOG, are based on the segmentation of the object of interest (b) and (d)Back to article page
