摘要：A method and apparatus for compressing digital image data to improve the efficiency of serial data transmission is disclosed. More specifically, the present invention accomplishes image transmission by providing multiple image processing modules, and then selecting the module that will process the entire in the most efficient manner, based upon the content of the data contained in the image. Image content is analyzed using hierarchical vector quantization.
