摘要
本文提出了一种基于完全重构滤波器组格形结构的正交小波滤波器的设计方法。通过对Lossless完全重构滤波器组加上规则性限制 ,正交小波滤波器的定制问题就转化为完全重构滤波器组的优化设计问题。实验仿真结果表明 。
An orthogonal wavelet filter design method based on the lattice structure of perfect reconstruction filter bank, is proposed in this paper. The combination of the Lossless perfect construction filter bank and regularity restriction, the custom-design of the orthogonal wavelet filter is transformed to the optimal design of a perfect reconstruction filter bank. Experimental results show this method is an effective custom design algorithm for the orthogonal wavelet filter.
