This algorithm combined joint-component vector quantization respectively with zero block and zero tree coding, scanned three component of color image separately and simplified separate coding into joint scanning and joint encoding.

• 该方法将联合色彩分量矢量量化和零块、零树编码方法巧妙结合，把彩色图像的三个色彩分量单独扫描，单独编码的过程简化为联合扫描和联合编码的过程。
