... This task approximates the gradient at each pixel of an image by doing least-squares fitting of a plane to the 3x3 array of values centred on each pixel. ... The user can choose between a cartesian representation (in which the output images record the x and y components of the gradient) or a polar representation (in which the output images are the magnitude and azimuth of the gradient.) ... No gradient value is calculated at the edge: nulls are stored in the output at these pixels. ...
