Abstract
Color image quantization using a hierarchical perceptual color model is disclosed. In one embodiment, a method constructs a clustering space of an image having a number of pixels, based on a color perception model. The clustering space includes a number of significant pixels, where each of the significant pixels does not have a parent pixel within the clustering space. The colors of the image are quantized based on these significant pixels. The remaining pixels have their colors mapped to one of the quantized colors.
