基于二进提升格式构造具有高阶消失矩的二进小波滤波器
Based on the Dyadic Lifting Scheme to Construct Dyadic Wavelet Filter with Higher-order Vanishing Moments
摘要
Abstract
Article use lifting scheme and dual binary scheme, respectively constructs the new ascension has high 8 order disappear moment binary wavelet filter and high order 6 disappear moment of dual lifting binary wavelet filter. The first step:To construct Mallat B - spline dyadic wavelet ( r = 1) expand, through a lot of calculation, experiment repeatedly, finally proved that can get construct new B - spline dyadic wavelet method; The second step:using the new method of constructing binary wavelet, constructs the new B - spline dyadic wavelet ( r = 2) as the initial binary wavelet filter, and then based on the binary scheme and dual binary scheme, ascension for three times, respectively is deduced with limited length, linear phase, high order vanished moments of binary wavelet filter and dual lifting binary wavelet filter, and the ascension of the binary wavelet filter which are not avail⁃able through promotion Sweldens scheme to calculate, there can only be described in this article the binary scheme for ascension.关键词
