Nonseparable biorthogonal wavelet packets in L/sup 2/(R/sup 2/)
Qingjiang Chen, Zhengxing Cheng · 2005
The notion of univariate and multivariate orthogonal wavelet packets has been generalized. First, the definition for nonseparable biorthogonal bivariate wavelet packets is given and a procedure of constructing them is described. Second, the biorthogonality property for biorthogonal bivariate wavelet packets is studied.
