本文从消失矩条件出发,基于二进提升方案,提出了一种新的构造提升二进小波滤波器的方法,此方案不但可构造二进小波滤波器而且可构造双正交小波滤波器,其次,具体的选用3次B-样条二进小波滤波器作为初始滤波器,通过调整构造定理中提升参数的形式,构造出满足实际需要的具有高阶消失矩的二进小波滤波器.
In this paper, based on the condition of vanishing moment, based on the binary lifting scheme, a new method to construct a binary wavelet filter is proposed. This scheme can not only construct the binary wavelet filter but also construct the biorthogonal wavelet filter, , The cubic B-spline binary wavelet filter is selected as the initial filter, and the binary wavelet filter with higher-order vanish moments is constructed to meet the actual needs by adjusting the form of the lifting parameters in the structure theorem.
