摘 要
小波变换用于图象压缩时,小波基的一些性质与编码的效果有很大的关系。本文在实验数据的基础上分析了小波的正交性、双正交性与正则性和消失距对静态图象编码的影响,从而给出了选择的原则。

The Choice of Wavelet Bases in Image Compression

()

Abstract
When wavelet transformation is applied to image compression,some of the properties of wavelet bases have some relations With coding effect.Based on the expriments ,this paper analyses what effects the orthonormal or biorthogonal bases and its regularity and vanishing moments have on static image coding. Thus, the principle of the choices is given.
