The Optimal Intelligent Algorithm on Orthogonal Five-Variate Wavelet Packets
In this article, the notion of orthogonal nonseparable four-dimensional wavelet packets which is the generalizaion of orthogonal univariate wavelet packets is introduced. A new approach for constructing them is presented by iteration method. The orthogonality properties of five-dimensional wavelet packets are discussed. Three orthogonality formulas concerning these wavelet packets are estabished.
