【摘要】 出于图像存储和图像通信的考虑,良好的图像编码技术不仅要求实现高压缩率和高保真度,还应该满足诸如渐进传输等网络应用的需要.在Shapiro 提出的嵌入式零树编码算法的基础上加以改进,可以更好的适应对渐进式传输的要求.通过实验结果分析,证实了算法的正确性和有效性。更多还原

【Abstract】 With the development of computer multimedia technology,we expect the coming up of imagecompression with higher performance.With regard to image storing and communication,the better imagecoding technology should not only achieve high compressing ratio and quality,but also meet such Internetapplication as progressive transmission,Improved on the basis of EZW presented by Shapiro,thealgorithm can better apply to progressive transmission.After careful analysis on the data obtained fromthe experiment,the efficiency and reliability of the algorithm has been proved.更多还原
