conference on Wavelet applications in signal and image processing VII
作者: Klappenecker, A Texas A&M Univ Dept Math College Stn TX 77843 USA
We show how periodized wavelet packet transforms and periodized wavelet transforms can be implemented on a quantum computer. Surprisingly, we find that the implementation of wavelet packet transforms is less costly th... 详细信息

IEEE International conference on image processing
作者: Bala, E Ertuzun, A Bogazici Univ Dept Elect Elect Engn Istanbul Turkey
The developments in wavelet theory have given rise to the wavelet thresholding method, for extracting a signal from noisy data [1,2]. Multiwavelets, wavelets with several scaling functions, have recently been introduc... 详细信息

conference on wavelets - applications in signal and image processing Ix
作者: Malgouyres, F Univ Calif Los Angeles Dept Math Los Angeles CA 90095 USA
This paper deals with a restoration (both denoising and deblurring) method. For instance in the case of denoising, this latter is only a small modification from the usual wavelet thresholding. However, it has the sign... 详细信息

wavelets - applications in signal and image processing x conference
作者: Jalobeanu, A Blanc-Feraud, L Zerubia, J NASA Ames Res Ctr RIACS USRA Moffett Field CA USA
We propose to model satellite and aerial images using a probabilistic approach. We show how the properties of these images, such as scale invariance, rotational invariance and spatial adaptivity lead to a new general ... 详细信息

wavelets - applications in signal and image processing x conference
作者: Peotta, L Granai, L Vandergheynst, P Swiss Fed Inst Technol Signal Proc Inst CH-1015 Lausanne Switzerland
Very low bit rate image coding is an important problem regarding applications such as storage on low memory devices or streaming data on the internet. The state of the art in image compression is to use 2-D wavelets. ... 详细信息

wavelets - applications in signal and image processing x conference
作者: Abhayaratne, GCK Piella, G Pesquet-Popescu, B Heijmans, H Ctr Math & Comp Sci CWI NL-1090 GB Amsterdam Netherlands
A class of adaptive wavelet transforms that map integers to integers based on the adaptive update lifting scheme is presented. The main feature in the adaptive update lifting scheme is that the update lifting step, wh... 详细信息

wavelets - applications in signal and image processing x conference
作者: Sallee, P Olshausen, BA Univ Calif Davis Dept Comp Sci Davis CA 95616 USA
Overcomplete wavelet representations have become increasingly popular for their ability to provide highly sparse and robust descriptions of natural signals. We describe a method for incorporating an overcomplete wavel... 详细信息

conference on Wavelet applications in signal and image processing VII
作者: Baraniuk, R Rice Univ Dept Elect & Comp Engn Houston TX 77005 USA
The more a;priori knowledge we encode into a signal processing algorithm, the better performance we can expect. In this paper, we overview several approaches to capturing the structure of singularities ledges, ridges,... 详细信息

wavelets - applications in signal and image processing x conference
作者: Papadakis, M Gogoshin, G Kakadiaris, IA Kouri, DJ Hoffman, DK Univ Houston Dept Math Houston TX 77204 USA
In this paper we present a non-separable multiresolution structure based on frames which is defined by radial scaling functions of the form of the Shannon scaling function. We also construct the resulting frame multiw... 详细信息

作者: Unser, M Blu, T Swiss Fed Inst Technol Biomed Imaging Grp CH-1015 Lausanne Switzerland
Compact support is undoubtedly one of the wavelet properties that is given the greatest weight both in theory and applications. It is usually believed to be essential for two main reasons : (1) to have fast numerical ... 详细信息
