Abstract
We study the perceptual problem related to image quantization from an optim ization point of view, using different metrics on the color space. A conseq uence of the results presented is that quantization using histogram equaliz ation provides optimal perceptual results. This fact is well known and wide ly used but, to our knowledge, a proof has never appeared on the literature of image processing.
