As Figure 7.63 shows, when you pick any of the coefficient fields in the
User Kernel setup panel, the calculator pad appears. To change a coefficient
value, enter the new value in the calculator (range: –128 to 127) and pick the
button. Repeat the process for all other coefficients that require new
values.
Example: If you were to enter the coefficient values shown below . . .
. . . the kernel would operate exactly as the Sobel X kernel described earlier.
Kernel Contrast
The Image Kernel selection panel shown in Figure 7.63 contains a field
labeled Contrast . The state of this field (active or inactive) depends on
which kernel is selected. Thus, the Contrast field is active for all kernel
selections; however, when User 3x3 or User 5x5 is selected, the state of the
