I have a simple idea about that. As for a gray image, the maximum
brightness is 255, the minimum brightness is 0,and the interval is 256.
Correspondingly, for a special image, the maximun brightness is Bmax,
the minimum is Bmin, so the normalized contrast of a pixel (whose
brightness is B) should be ((Bmax-Bmin)/256)*B.

Hi
What is contrast normalization for an image? Where can I get material
on the web regarding this?
