摘要: A color quantization method is presented, which based on the analysis of histogram at different resolutions computed a Gaussian pyramid input image. Criteria persistence and dominance peaks pits histograms are introduced to detect modes in image define reduced colormap. Important features are, besides its limited computational cost, possibility obtain quantized images with variable number colors, depending user's need, that colors resulting does not need be priori fixed.
