摘要
在二进提升方案相关理论的基础上,结合消失矩条件,提出一种具有高阶消失矩的提升二进小波滤波器的构造方法,并选取适当的提升参数,构造了具有紧支撑、对称性和高阶消失矩的提升二进小波滤波器。
A construction method of lifting dyadic wavelet filters with higher order of vanishing moments based on dyadic lifting schemes theory is put forword.Meantime we design lifting dyadic wavelet filters with compact support,symmetry and higher order of vanishing moments by selecting the appropriate lifting parameters.
