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
Minimum-energy frames associated with refinable function of arbitrary integer dilation factor
Yongdong Huang,Zhengxing Cheng +1 more
TL;DR: In this article, the authors studied the minimum energy frame decomposition and reconstruction problem in terms of an inequality condition on the Laurent polynomial symbols of the refinable functions and gave a constructive proof that when Ψ does exist, d functions with compact support are sufficient to constitute Ψ, and presented a explicit formula of constructing Ψ.
Journal ArticleDOI
Construction of a class of compactly supported orthogonal vector-valued wavelets
Lei Sun,Zhengxing Cheng +1 more
TL;DR: In this article, a necessary and sufficient condition on the existence of orthogonal vector-valued wavelet is derived and a (L ǫ + 1)-length compactly supported wavelet system is constructed.
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.
Journal ArticleDOI
Construction of trivariate biorthogonal compactly supported wavelets
TL;DR: In this paper, a sufficient condition on the existence of a pair of trivariate biorthogonal scaling functions is derived, and the pair of nonseparable or separable wavelets can be obtained from the pair.
