An algebraic approach to discrete dilations. Application to discrete wavelet transforms
We investigate the connections between continuous and discrete wavelet transforms on the basis of algebraic arguments. The discrete approach is formulated abstractly in terms of the action of a semidirect product A × Γ on `2(Γ), with Γ a lattice and A an abelian semigroup acting on Γ. We show that several such actions may be considered, and investigate those which may be written as deformations...
متن کاملDiscrete Affine Wavelet Transforms
In this paper we show that discrete affine wavelet transforms can provide a tool for the analysis and synthesis of standard feedforward neural networks. It is shown that wavelet frames for L2(IR) can be constructed based upon sigmoids. The spatia-spectral localization property of wavelets can be exploited in defining the topology and determining the weights of a feedforward network. Training a ...
متن کاملError-Free Arithmetic for Discrete Wavelet Transforms Using Algebraic Integers
In this paper a novel encoding scheme is introduced with applications to error-free computation of Discrete Wavelet Transforms (DWT) based on Daubechies wavelets. The encoding scheme is based on an algebraic integer decomposition of the wavelet coefficients. This work is a continuation of our research into error-free computation of DCTs and IDCTs, and this extension is timely since the DWT is p...
متن کاملContinuous and Discrete Wavelet Transforms
Rob A. Zuidwijk CWI E-mail: [email protected] Url: http://www.cwi.nl/cwi/projects/wavelets.html November 6, 1997 Abstract In this lecture, the continuous wavelet transform will be discussed and some attention will be given to the discrete wavelet transform. Finally, wavelet transforms on multidimensional data will be considered. The set-up of the lecture is as follows: 1. The continuous wavelet t...
متن کاملContinuous and Discrete Wavelet Transforms
This paper is an expository survey of results on integral representations and discrete sum expansions of functions in L(R) in terms of coherent states. Two types of coherent states are considered: Weyl–Heisenberg coherent states, which arise from translations and modulations of a single function, and affine coherent states, called “wavelets,” which arise as translations and dilations of a singl...
