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 該方法將聯(lián)合色彩分量矢量量化和零塊、零樹編碼方法巧妙結(jié)合,把彩色圖像的三個色彩分量單獨掃描,單獨編碼的過程簡化為聯(lián)合掃描和聯(lián)合編碼的過程。
