Answer 1

I don't know what this means exactly but start by looking at imquantize(), adapthisteq(), imhistmatch(), imadjust(), histeq(), qtdecomp(), etc. in the Image Processing Toolbox. By the way, are you talking about quantization spatially, or of the intensity values?

[Arpita Shanbhag]

It is only quatization

[Image Analyst]

I don't understand that comment.

[Arpita Shanbhag]

Both spatially and intensity levels

Answer 2

quantize

Again, this "Answer" also doesn't make any sense, nor does it answer the original poster's three year old question.
