Filtering Operations
Vertical Sobel Filtering Kernels
High Pass
The High Pass operation acts like a circular gradient high pass filter. It essentially extracts
high frequency details. This has the effect of highlighting all edges (gradients) in the image.
The kernel size can be 3, 5 or 7. The absolute clipping method is usually used with this fil-
tering operation. The kernels used by the Image Processing Tool are shown in the following
figure.

Laplacian Filter
The Laplacian operation also acts like a circular gradient filter. This has the effect of high-
lighting all 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
Processing Tool are shown in the following figure.
