文章以二进提升格式为基础,结合小波相关理论和消失矩条件,提出一种构造新的具有高消失矩二进小波滤波器的方法。该方法不仅可以构造二进小波滤波器还可以构造双正交小波滤波器。第一步:将4次B-样条二进小波滤波器作为初始小波滤波器;第二步:利用对构造定理中提升参数的调整,构造满足需求的具有对称性、紧支撑和高消失矩的提升小波滤波器。
Based on the binary lifting scheme, this paper proposes a new method to construct a new wavelet filter with high vanishing moment based on wavelet correlation theory and vanishing moment condition. This method can not only construct binary wavelet filter but also construct biorthogonal wavelet filter. The first step: 4 times the B-spline binary wavelet filter as the initial wavelet filter; The second step: the use of the structural parameters of the lifting parameters to adjust to meet the needs of the construction of symmetry, tight support and vanishing moments The lifting wavelet filter.
