WebFrame wavelets have been in the literature for many years. These can be viewed as the frame vectors for the usual dilation and translation unitary system onL2(R). In Chapter 5 … WebThis revised and expanded monograph presents the general theory for frames and Riesz bases in Hilbert spaces as well as its concrete realizations within Gabor analysis, wavelet analysis, and generalized shift-invariant systems. Compared with the first edition, more emphasis is put on explicit constructions with attractive properties.
WebThen, the collection of o.n. wavelets with the dimension function D f 2L2(R) : is an o.n. wavelet and D = Dg: is a path connected subset of L2(R). Variants of Problem 2.1 have been studied for other classes of wavelets such as Parseval wavelets. We say that 2L2(R) is a Parseval wavelet if its wavelet system is a Parseval frame.

WebDec 12, 2024 · However, the same problem for frame wavelets was solved by the first author [ 10 ]. A frame wavelet, or in short a framelet, is a function \psi \in L^2 (\mathbb {R}) such that the wavelet system ( 3.1) forms a frame for L^2 (\mathbb {R}). Hence, we require the existence of constants 0 < c ≤ d < ∞ such that WebJan 1, 2003 · In particular, we establish general principles and specific algorithms for constructing framelets and tight framelets, and we show how they can be used for systematic constructions of spline, pseudo-spline tight frames, and symmetric bi-frames with short supports and high approximation orders. Several explicit examples are …
