User 3x3, User 5x5 Kernels
The User 3x3 and User 5x5 kernels can be configured with coefficient
values that the user deems most appropriate for a specific inspection
application. Initially, these kernels are configured in the “identity” mode; that
is, the center coefficient is 1 and all other coefficients are 0, as shown below:

The result of these “identity” coefficients is that they have no effect on the
pixels in the image.
When you pick User 3x3 or User 5x5 in the Image Kernel selection panel,
the
button becomes active, as shown in Figure 7.63 (page 7–75).
When you then pick the
button, the User Kernel setup panel
appears, also shown in Figure 7.63.
