PRELIMINARY

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.
