A study on compactly supported orthogonal vector-valued wavelets and wavelet packets
Qingjiang Chen,Zheng-Xing Cheng +1 more
TL;DR: In this article, a necessary and sufficient condition on the existence of orthogonal vector-valued wavelets is derived by means of paraunitary vector filter bank theory, and an algorithm for constructing a class of compactly supported OVW wavelet packets is presented.
Journal ArticleDOI
Characteristics of a class of vector-valued non-separable higher-dimensional wavelet packet bases
TL;DR: In this article, a vector-valued non-separable higher-dimensional wavelet packets with an arbitrary integer dilation factor is introduced, and an approach for constructing vectorvalued higher dimensional wavelet packet bases is proposed.
Journal ArticleDOI
Construction and properties of orthogonal matrix-valued wavelets and wavelet packets☆
TL;DR: In this article, a necessary and sufficient condition on the existence of orthogonal matrix-valued wavelets is derived by virtue of paraunitary vector filter bank theory, and an algorithm for constructing compactly supported m-scale wavelets with arbitrary integer dilation factor m is presented.
Journal ArticleDOI
Existence and construction of compactly supported biorthogonal multiple vector-valued wavelets
TL;DR: In this article, it was shown that the existence of a pair of biorthogonal multiple vector-valued scaling functions guarantees the presence of pair of BVM wavelet functions.
Journal ArticleDOI
Affine pseudoframes for subspaces of L2(R) associated with a generalized multiresolution structure
TL;DR: In this article, the notion of an m-band generalized multiresolution structure (GMS) of L 2 (R ) is introduced and the definition and the characterization of affine pseudoframes for subspaces are given.
