how can I make an histogram shipping or stretching?

[rom391]

I want to accentuate the contrast on my greyscales image with histogram shipping or histogram stretching.  How can I make that?

Vision Development Module provides lookup functions you can use for that effect. Look at some of the functions located in the processing palette:

IMAQ UserLookup2, IMAQ MathLookup, IMAQ Equalize.

The Analysis palette contains functions you can use to compute the histogram of the image.
