The characteristics of a class of biorthogonal bivariable wavelet packets
Jun Lü, Hua Li · 2009
Wavelet analysis is a popular subject in science research. In this paper, the notion of univariate orthogonal wavelet packets is generalized. 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.
