Optimal image quantization, perception and the median cut algorithm
Cícero Mota, Jonas Gomes, MARIA I. A. CAVALCANTE · Anais da Academia Brasileira de Ciências · 2001
We study the perceptual problem related to image quantization from an optimization point of view, using different metrics on the color space. A consequence of the results presented is that quantization using histogram equalization provides optimal perceptual results. This fact is well known and widely used but, to our knowledge, a proof has never appeared on the literature of image processing.
