The Algorithm for the Construction of Two-dimensional Finite Wavelet Filter with Linear Phase

根据二维小波滤波器参数化理论,提出了一个具有可操作性的二维小波滤波器递推算法。用最简形式刻画了4阶标准正交中心对称矩阵,并证明了根据算法产生的线性相位滤波器的一个重要性质。

In terms of the formulated finite wavelet filters theory, this paper presented an iterating algorithm for the construction of two-dimensional finite wavelet filter with linear phase. The real unitary and center - symmetry matrices with size of were characterized and an important attribute of wavelet filter produced by the algorithm was proved.
