| 摘 要： | 嵌入式零树编码被认为是目前国际上最先进的图像编码方法之一，但该算法在编“孤立零”码时会造成比特位冗余．因此本文提出了基于零树的树形扫描的图像压缩编码方法．实验结果表明该方法在保证恢复图像具有良好视觉效果的前提下，提高了压缩比，缩短了编码时间．

| Abstract: | Embedded zerotrees wavelet (EZW)image coding algorithm is one of the most advanced image coding technologies in the world. But it has some deficiencies, one of which is that the vision character isn't considered in coding. In this paper, an image compression coding algorithm based on the tree style scanning was proposed. The experiment results show that this image coding performs better than that of the EZW in aspects of compression ratio and time of coding. |
