摘要
运用矩阵理论和时频分析方法研究多尺度双向矩阵值小波的性质.首先引进了多尺度双向矩阵值正交小波的概念,然后提供了短支撑多尺度双向矩阵值正交小波的构造算法,最后刻画一类多尺度双向矩阵值正交小波包的特征.
Properties of muhiscale two-directional matrix-valued wavelets are studied by using matrix theory and time-frequency method. Firstly, the concept of orthogonalmuhiscale two-directional matrix-valued wavelets is intro- duced. Secondly, a eonstructivealgorithm formultiseale two-directional matrix-valued wavelets is presented. Finally, a class of muhiscale two-directionalmatrix-valued wavelet packets are characterized.
