A class of four-band symmetric orthogonal wavelet construction
Juan Su · Journal of Changsha University of Science & Technology · 2007
We study some special properties and factorization structure of polyphase matrix of 4-band orthogonal symmetric wavelet.Based on the factorization,a program for constructing 4-band orthogonal symmetric wavelet filter banks is presented.Characteristics of scaling and wavelet functions are given at last.
