摘要 在讨论小波变换及EZW算法的基础上,分析了EZW算法的不足 通过对低频子带单独编码、在高频子带进行边缘检测、分类编码等措施的研究,提出了一种基于EZW算法的改进算法 实验结果表明:从峰值信噪比及编 /解码时间对照。 Based on discussing the wavelet transform and algorithm of EZW, the shortage of EZW is analyzed. Coding the subbands of low-scaled separating,testing the border of the subbands of high-scaled and the classified code are adopted. The experiment results show that the improved algorithm is superior to EZW by contrasting PSNR/db, the time of coding and decoding.
