Abstract :
A vector quantization compression system is presented which is suitable for use in commercial applications, i.e., efficient enough to encode a wide variety of images and simple enough to decode the images in real time using software (for machine compatibility). A fixed-rate code with unbalanced tree structure is used, and a method of unbalanced tree growing is extended. Simple prediction techniques are applied to improve coded image quality
