摘要

多小波是近几年小波理论研究的一个重要方向

但在图像压缩中还没有成功的例子;本文综述了多小波的重要性质

对几个常用多小波作了预处理;图像压缩应用实验结果表明平衡处理比预滤波效果好

尤其是Opt-recl多小波能精确重构

无边界失真

在一定的压缩比下可达到很高的峰值信噪比PSNR.

Abstract

Some important performances of multiwavelets are summarized

and pre-processing of several multiwavelets are proposed.An image compression example is given

with satisfactory effects.The results show that the multiwavelet transform of Opt-recl has non-boundary distortion

and can obtains high peak signal-to-noise ratio (PSNR).
