摘要
多小波是近年才发展起来的矢量小波理论,同时具有正交性、对称性、短支撑和较大的消失矩等多个良好特性,这就意味着多小波将可以对信号提供一种更新的分析手段。本文充分利用多小波分解系数的结构,采用EBCOT图像压缩算法,对多小波系数进行压缩处理,得到一种比较有效的多小波图像压缩方法。
Multiwavelet is a theories of vector wavelet that developed just in recent years.It has many good chatacters,for example：orthog-onality,short support,more Vanishing Moments,etc.This means that multi-wavelet can provide a newer means to analyze the signal.This text will make use of the structure of decomposition coefficient of muhiwavelet, adopt the EBCOT, carrying on compressing the coefficient of multiwavelet, get a kind of more effective compression methods of multiwavelet.
