摘要
通过研究M-带对称尺紧支度滤波器的分解形式,得到了一种简单的构造方法.特别地,给出了4-带对称紧支尺度滤波器的构造方法.然后基于酉扩充原则构造了一类4-带紧支对称小波框架系统,利用这种系统可以得到彭立中等(2004)介绍的具有优美结构的小波.
By studying the factorization metric scaling filter, a simple method of of the M-band compactly supported symconstruction is gained. Particularly, the 4-band compactly supported symmetric scaling filter is constructed. Then, the 4- band compactly supported symmetric wavelet frame system are given with the UEP. Based on this system, the beautiful structure wavelet which introduced by Peng, et al. (2004) is obtained.
