摘要:

在二进提升方案相关理论的基础上,结合消失矩条件,提出一种构造提升二进小波滤波器的新方法。此方法由二进小波滤波器出发,可以构造具有更高阶消失矩的提升二进小波滤波器。同时,考虑小波滤波器所具有的特性,通过选取适当的提升参数,具体构造了具有紧支撑、对称性和高阶消失矩的提升二进小波滤波器。

Abstract:

A new construction method of lifting dyadic wavelet filters based on dyadic lifting schemes theory and vanishing moments is put forward. Lifting dyadic wavelet filters with higher order of vanishing moments can be constructed from dyadic wavelet filters. Meantime, considering the characteristic of wavelet filters, the paper designs lifting dyadic wavelet filters with compact support, symmetry and higher order of vanishing moments by selecting the appropriate lifting parameters.
