Abstract

The paper describes an original method to represent chrominance in color images and video. This method can be combined with an arbitrary technique of luminance representation or compression. The two chrominance components are represented by one scalar signal obtained using vector quantization. The luminance is encoded entirely independently from chrominance. The scalar representation of chrominance exhibits high redundancy and high correlation with luminance. They both are strongly reduced using differential coding with adaptive prediction that exploits the information about edges extracted from decoded luminance component.
