The Intelligent Traits Regarding Biorthogonal Trivariate Wavelet Packs
Zhixia Duan, Yumin Yu · 2010
In this paper, the notion of biorthogonal nonseparable trivariate wavelet packs, which is the generalization of biorthogonal univariate wavelet packs, is introduced. A new procedure for constructing them is presented. Their biorthogonality property is characterized by the filter bank theory and time-frequency analysis method. Three biorthogonality formulas concerning these wavelet packs are established.
