高阶消失矩的二进小波滤波器的构造方法
Constructed Method of Dyadic Wavelet Filter of Higher-order Vanishing Moments
摘要
Abstract
Based on the dyadic lifting scheme,combined with the condition of vanishing moments and related wavelet theory,deduce a new two constructor method has higher-order moments vanish into the wavelet filter. First,B-spline dyadic wavelet proposed by Mallat is expanded into new methods to derive two wavelet filter structure B-spline. Then,based on binary format,with r = 1,m = 2 B-spline dyadic wavelet filter as the initial dyadic wavelet filter,after repeated lifting and a lot of calculations,construct a new binary wavelet filter with 7 vanishing moments. Finally,based on the dual binary format ascension,select the appropriate freedom parameters for the three lift-ing to initial dyadic wavelet reconstruction high-pass filter,deducing lifting dyadic wavelet filters with compact support,linear phase,dual lifting 7-order vanishing moments.关键词
