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
