Characteristics of bivariate biorthogonal wavelet packets
Jianfeng Zhou, Yong Liu · 2008
Multivariate wavelets are a popular subject in science research. In this paper, the notion of univariate orthogonal wavelet packets is generalized. First, the definition of biorthogonal nonseparable bivariate wavelet packets is given and a procedure for constructing them is presented. Next, the biorthogonality property of biorthogonal bivariate wavelet packets is investigated.
