Table 7.5 correlates the LUT with the signed/unsigned state of the input
image from a convolution kernel, and indicates the characteristics of the
resulting output image.

All input images have signed or unsigned gray scale values.
NOTE: The LUT assumes that the input image will be signed or unsigned
as indicated in the table. (For example, the
Sign
and
Absolute
LUTs both
“expect” a signed image from, say a
Sobel X
or
Y Edge
kernel; whereas,
the
Threshold
LUT expects an unsigned image.)
