Parameterization and Algebraic Structure of 4-Band Orthogonal Wavelet Filter Banks
Quan Hong-yue · 2006
In this paper,we study the factorization of polyphase matrix of 4-band orthogonal wavelet.Based on the factorization,a program for constructing 4-band orthogonal wavelet filter banks is presented.For the parameterization of wavelet space,one can well study the algebraic structure of filter banks.
