The properties of biorthogonal bivariate wavelet packets
Jian-Guo Shen, Deyou Yuan · 2007
In this paper, the notion of univariate orthogonal wavelet packets is generalized. First, the definition of nonseparable biorthogonal bivariate wavelet packets is given and a procedure for constructing them is presented. Next, the biorthogonality properties of biorthogonal bivariate wavelet packets is investigated.
