摘要: 本文提出一种新的选择适于图像编码应用的双正交小波基的方法。通过用几个已被证实是与图像编码密切相关的小波基评价标准,对双正交小波中分析与综合函数交换使用时的编码性能进行全面的比较研究,选出了适合图像编码的分析或综合小波基,并作了编码实验检验。

Abstract: A new method for choosing biorthogonal wavelet bases which is suitable for image coding is presented. A thoroughly comparative study is made and biorthogonal wavelet bases suitable for image coding are selected by using several criteria of evaluation proven to be closely related to image coding. It is verified by coding experiment. -
