Permutation of conjugate quadrature filter

After some permutating of a conjugate quadrature filter (CQF), new CQFs can be derived. In this paper, we give a method to construct bivariate orthogonal wavelets by permutating of separable two-dimensional CQF. Non-separable bivariate orthogonal wavelets can be obtained by this method. Finally, an example is provided to demonstrate this method.
