Basic Operation and Features

3.11.1 Gray Scale Test Image

The gray scale test image consists of lines with
repeated gray scale gradients ranging from 0 to
255. The first line starts with a gray value of 0 on
the first pixel, in the second line the first pixel
has a gray value of 1, in the third line the first
pixel has a gray value of 2, and so on.
The mathematical expression for the test image
is: gray level = [x + y] MOD 256. This expression
is shown graphically in Figure 3-31.
