本文给出了一类对称—反对称多小波滤波器组参数化设计方法,并在此基础上提出了新的多小波零树编码方案.实验表明,与常用的9-7单小波相比,我们所设计的双正交对称—反对称多小波可使编码性能有较大幅度的改善.

In this paper,we propose a parameterization design method for the symmetric-antisymmetric multiwavelet filter bank.Then,based on it,we present a new multiwavelet zerotree compression algorithm.Experimental results show that our multiwavelets can perform much better than the commonly used 9-7 biorthogonal wavelet in compression efficiency.
