摘要
小波提升方案是继多分辨分析之后的另一种非常有效的构造小波滤波器的方法。以构造双正交小波的Cohen-Daubechies-Feauveau定理为基础,利用提升方式构造了一个包含Cohen,Daubechies和Feauveau的著名97小波滤波器(CDF97)的小波滤波器族,获得了新的97小波滤波器,其图像压缩性能与CDF97相当,但其复杂度已大大降低,有利于ASIC的设计。
The lifting scheme is an efficient method for construction of the wavelet after multiresolution. Based on the lifting scheme and the Cohen-Daubeehies-Feauveau Theorem for constructing biothogonal wavelets, a class wavelet families involving CDF97(C97) are constructed, which not only has excellent compression performance, but also is very suitable for the implementation of ASIC. The computational complexity of the new lifting wavelet filter is enormously reduced.
