A Study on Characteristics of Biorthogonal Two-Dimensional Wavelet Packets
De Yao Song, Xiao Feng Wang · Key engineering materials · 2010
Wavelet analysis is a popular subject in science research. The notion of univariate orthog- onal wavelet packets is generalized. The definition of biorthogonal nonseparable two-dimensional wavelet packets is presented and a procedure for constructing them is proposed. The biorthogonality property of bivariate wavelet packets is investigated. Two biorthogonality formulas regarding these wavelet packets are established.
