In this paper, a novel way to design biorthogonal filter banks and wavelets is proposed. Perfect reconstruction (PR) filter banks are roughly separated into orthogonal (paraunitary) and biorthogonal filter banks. Biorthogonal filter banks have more degrees of freedom than orthogonal ones. Thus they

A method is presented for the design of a class of two-dimensional (2-D) stable digital filters satisfying prescribed magnitude and constant group delay specifications. The design method generates a 2-D digital transfer function which is a product of two transfer functions H,(z,,z,) and H,(z,,z,), c
