Abstract

In [7], a large class of bi-variate finite orthogonal wavelet filters was constructed. In this paper, we propose a more general expression of the filter bank with linear phase which is called standard method. Beside this, a non-standard method is also presented. A interesting example is also given. By using this non-separable wavelet filter bank, we present a novel method of segmenting a image into two parts: one part is texture with special property and another part is image of piecewise smooth in some sense.
