Since then, the field of image segmentation has evolved very quickly and has undergone great change (Zhang, 2001a). doom timeline photoWebSobel operator performs a 2-D spatial gradient operation on an image to enhance the edges. The operator consists of a pair of 3-by-3 convolution kernels (two for the two perpendicular directions) that are separately applied to an image to produce the approximate gradients for each pixel for detecting edges in vertical and horizontal directions. doom\u0027s gate
