Multiresolution analysis by infinitely differentiable compactly supported functions

open access: yes, 1995
[he paper is concerned with the introduction and study of multiresolution analysis based on thie uip function, which is an infinitely differentiable function supported on [0,2]. Such analysis i,. necessarily, nonstationary.

A Wavelet Toolbox for Large Scale Image Processing

open access: yes, 1999
The wavelet transform has proven to be a valuable tool for image processing applications, like image compression and noise reduction. In this paper we present a scheme to process very large images that do not fit in the memory of a single computer, based

Q-deformed and λ-parametrized A-generalized logistic function induced Banach space valued multivariate multi-layer neural network approximations

open access: yes
Here we research the multivariate quantitative approximation of Banach space valued continuous multivariate functions on a box or RN, N ∈ N, by the multivariate normalized, quasi-interpolation, Kantorovich type and quadrature type neural network ...

Interpolating Refinable Functions And Wavelets For General Scaling Matrices

open access: yes, 1997
This paper introduces a general procedure for constructing interpolating re- nable functions for arbitrary dilation matrices. The key ideas are based on the construction presented in [24].

Symmetric Orthonormal Scaling Functions and Wavelets with Dilation Factor d = 4

open access: yes, 1997
It is well known that in the univariate case, up to an integer shift and possible sign change, there is no dyadic compactly supported symmetric orthonormal scaling function except for the Haar function.

Scattered Node Compact Finite Difference-Type Formulas Generated from Radial Basis Functions

open access: yes, 2008
In standard equispaced finite difference (FD) formulas, symmetries can make the order of accuracy relatively high compared to the number of nodes in the FD stencil. With scattered nodes, such symmetries are no longer available.

On Dual Wavelet Tight Frames

open access: yes, 1995
A characterization of multivariate dual wavelet tight frames for any general dilation matrix is presented in this paper. As an application, Lawton's result on wavelet tight frames in L (IR) is generalized to the n-dimensional case.

Approximation From Shift-Invariant Subspaces of ...

open access: yes, 1991
: A complete characterization is given of closed shift-invariant subspaces of L 2 (IR d ) which provide a specified approximation order. When such a space is principal (i.e., generated by a single function), then this characterization is in terms of ...
