wavelets - applications in signal and image processing X conference
作者: Atkinson, I Kamalabadi, F Jones, DL Do, MN Univ Illinois Dept Elect & Comp Engn Urbana IL 61801 USA
In this paper, we illustrate how a recently proposed wavelet-based estimation scheme for 2-D multichannel signals can utilize an overcomplete wavelet expansion or the BayesShrink adaptive wavelet-domain threshold to i... 详细信息

Proceedings of SPIE - The International Society for Optical Engineering 1994年 2303卷 214-225页
作者: Xia, Xiang-Gen Suter, Bruce W. Air Force Inst of Technology Wright-Patterson AFB United States
Malvar wavelets or lapped orthogonal transform has been recognized as a useful tool in eliminating block effects in transform coding. Suter and Oxley extended the Malvar wavelets to more general forms, which enable on... 详细信息

conference on wavelet applications in signal and image processing Vii
作者: Carré, P Richard, N Fernandez, C Paquereau, J SIC Lab IRCOM UMR CNRS 6615 F-86960 Futuroscope France
In this paper, we propose an original decomposition scheme based on Meyer's wavelets. In opposition to a classical technique of wavelet packet analysis, the decomposition is an adaptative segmentation of the frequ... 详细信息

IEEE International conference on image processing (ICIP 2000)
作者: Scott, C Nowak, R Rice Univ Houston TX 77005 USA
Despite their success in other areas of statistical signal processing, current wavelet-based image models are inadequate for modeling patterns in images, due to the presence of unknown transformations inherent in most... 详细信息

conference on wavelet applications in signal and image processing V
作者: Lai, YK Kuo, CCJ Univ. of Southern California (United States)
The traditional mean-squared-error (MSE) or peak-signal-to-noise-ratio (PSNR) error measures are mainly focused on the pixel-by-pixel difference between the original and compressed images. Such metrics are improper fo... 详细信息

wavelets - applications in signal and image processing X conference
作者: Antoine, JP Jacques, L Catholic Univ Louvain Inst Phys Theor B-1348 Louvain Belgium
Two-dimensional wavelet analysis with directional frames is well-adapted and efficient, for detecting oriented features in images. but, for (quasi-) isotropic components, it is unnecessarily redundant. Using wavelets ... 详细信息
