数量矩阵伸缩的高维矩阵值小波包
Multivariate Matrix-Valued Wavelet Packets Associated with a Quantity Dilation Matrix
【摘要】 研究高维矩阵值双正交小波包的构造及性质.引进了基于数量矩阵伸缩的紧支撑高维矩阵值正交小波包的概念.运用傅立叶变换、积分变换和算子理论,讨论了它们的性质,得到关于高维矩阵值小波包的双正交公式.
【Abstract】 This article is to investigate biorthogonal matrix-valued wavelet packets in higher dimensions.A class of compactly supported biorthogonal matrix-valued multivariate wavelet packets are defined and constructed.The properties of the biorthogoanl multivariate matrix-valued wavelet packets are investigated and biorthogonality formulae are obtained by using the Fourier transform and operator theoy.
