Horizontal Sobel Filter
The Horizontal Sobel operation acts like a gradient filter. This has the effect of highlighting
horizontal edges (gradients) in the image. The kernel size can be 3, 5 or 7. The absolute clip-
ping method is usually used with this filtering operation. The kernels used by the Image Proc-
essing Tool are shown in the following figure.
