A method of image quantization is provided which includes the following steps: creating an optimal palette (2) for an image using full three-dimensional deviation and capable of assigning less colors to smooth, transitional regions of the images; constructing a color look-up table (4) to efficiently map arbitrary colors to colors of the optimal palette using a sweep-list method; and mapping (5) an image to a color quantizing image using an over-compensated and adaptively damped error diffusion method.
