Binary gradient contours
WebNov 3, 2014 · Here, we define the non binary gradient contour of a 3x3 gray scale image patch. Procedure: (1) The gradient between pairs of pixels is computed along a closed path around the central pixel S and (2) The gradients are not binarized because we lose the information during process of binarization.
