Abstract
A method for reducing chrominance entropy in a digital color image. This method is practiced in relation to pixels in the two chrominance channels in a luminance-chrominance-chrominance representation of the image. The method involves shifting the chrominance values of selected low-luminance or high-luminance pixels toward (or to) another chrominance value which will result in a net chrominance entropy reduction in the subject channel.
