摘要
本文提出了一种基于余弦函数的二元紧支撑正交小波滤波器的构造方法。这种构造方法简单易行,能够通过选取不同的参数而设计出不同的小波滤波器。最后,给出了算例。
In this paper, a novel construction of bivariate orthogonal compactly supported wavelet filter based on the cosine function is proposed. This method is simple and convenient, because one can easily design different wavelet filters by choosing different references. Finally, some examples are given.
