The lifting scheme: A construction of second generation wavelets

W Sweldens - SIAM journal on mathematical analysis, 1998 - SIAM
We present the lifting scheme, a simple construction of second generation wavelets; these
are wavelets that are not necessarily translates and dilates of one fixed function. Such …

The lifting scheme: A custom-design construction of biorthogonal wavelets

W Sweldens - Applied and computational harmonic analysis, 1996 - Elsevier
We present the lifting scheme, a new idea for constructing compactly supported wavelets
with compactly supported duals. The lifting scheme uses a simple relationship between all …

Factoring wavelet transforms into lifting steps

I Daubechies, W Sweldens - Journal of Fourier analysis and applications, 1998 - Springer
This article is essentially tutorial in nature. We show how any discrete wavelet transform or
two band subband filtering with finite filters can be decomposed into a finite sequence of …

Building your own wavelets at home

W Sweldens, P Schröder - Wavelets in the Geosciences, 2005 - Springer
Wavelets have been making an appearance in many pure and applied areas of science
and engineering. Computer graphics with its many and varied computational problems has …

Lifting scheme: a new philosophy in biorthogonal wavelet constructions

W Sweldens - Wavelet applications in signal and image …, 1995 - spiedigitallibrary.org
In this paper we present the basic idea behind the lifting scheme, a new construction of
biorthogonal wavelets which does not use the Fourier transform. In contrast with earlier papers …

Spherical wavelets: Efficiently representing functions on the sphere

P Schröder, W Sweldens - Proceedings of the 22nd annual conference …, 1995 - dl.acm.org
Wavelets have proven to be powerful bases for use in numerical analysis and signal
processing. Their power lies in the fact that they only require a small number of coefficients to …

[PDF][PDF] Wavelets and the lifting scheme: A 5 minute tour

W Sweldens - ZAMM-Zeitschrift fur Angewandte Mathematik und …, 1996 - dwm.narod.ru
The purpose of this paper is to give a very short,\nuts and bolts", introduction to the lifting
scheme and provide references for further reading. The lifting scheme is a new method for …

Wavelet transforms that map integers to integers

AR Calderbank, I Daubechies, W Sweldens… - Applied and …, 1998 - Elsevier
Invertible wavelet transforms that map integers to integers have important applications in
lossless coding. In this paper we present two approaches to build integer to integer wavelet …

An overview of wavelet based multiresolution analyses

B Jawerth, W Sweldens - SIAM review, 1994 - SIAM
In this paper an overview of wavelet based multiresolution analyses is presented. First, the
continuous wavelet transform in its simplest form is discussed. Then, the definition of a …

Differential unitary space-time modulation

BM Hochwald, W Sweldens - IEEE transactions on …, 2000 - ieeexplore.ieee.org
We present a framework for differential modulation with multiple antennas across a
continuously fading channel, where neither the transmitter nor the receiver knows the fading …
