Local and global multiscale image classification
收藏 引用
Proceedings of SPIE - The International Society for Optical Engineering 1994年 2303卷 485-493页
作者: Boucher, Jean-Marc Benie, Goze Fau, Regis Plehiers, Stephane Ecole Natl.e Superieure des Telecommunications Brest Cedex Fr
Different unsupervised Bayesian classification algorithms can be associated to a multiscale image analysis procedure leading to improvements, both in computation time and classification performances. Two kinds of algo... 详细信息

wavelet denoising of EEG signals and identification of evoked response potentials
收藏 引用
Proceedings of SPIE - The International Society for Optical Engineering 1994年 2303卷 91-104页
作者: Carmona, Rene A. Hudgins, Lonnie H. Univ. of California/Irvine Irvine CA USA
The purpose of this study is to apply a recently developed wavelet based de-noising filter to the analysis of human electroencephalogram (EEG) signals, and measure its performance. The data used contained subject EEG ... 详细信息

MULTIRESOLUTION TOMOGRAPHIC RECONSTRUCTION USING WAVELETS
收藏 引用
1994 IEEE International conference on image processing (ICIP-94)
作者: DELANEY, AH BRESLER, Y UNIV ILLINOIS URBANAIL 61801
We show how the separable two-dimensional wavelet representation leads naturally to an efficient multiresolution tomographic reconstruction algorithm. This algorithm is similar to the conventional filtered backproject... 详细信息

Enhancement of decompressed images at low bit rates
收藏 引用
Proceedings of SPIE - The International Society for Optical Engineering 1994年 2303卷 366-377页
作者: Gopinath, Ramesh A. Lang, Markus Guo, Haito Odegard, Jan E. IBM Thomas J. Watson Research Cent. Hawthorne NY USA
Transform coding at low bit rates introduces artifacts associated with the basis functions of the transform. For example, decompressed images based on the DCT (discrete cosine transform) - like JPEG - exhibit blocking... 详细信息

WAVELET-DOMAIN TEXTURE MODELING FOR IMAGE COMPRESSION
收藏 引用
1994 IEEE International conference on image processing (ICIP-94)
作者: RYAN, TW SANDERS, LD FISHER, HD SCI APPLICAT INT CORP TUCSONAZ 85710
High quality image compression algorithms are capable of achieving transmission or storage rates of 0.5 to 1.0 bits/pixel with low degradation in image quality. In order to obtain even lower bit rates, the authors rel... 详细信息

Class of smooth nonseparable N-dimensional scaling functions
收藏 引用
Proceedings of SPIE - The International Society for Optical Engineering 1994年 2303卷 64-74页
作者: Maesumi, Mohsen Lamar Univ. Beaumont TX USA
wavelets of compact support are an important tool in many areas of signal analysis. A starting point for the construction of such wavelets is the scaling function, the solution of the dilation equation. We study the d... 详细信息

Synthesis of regular very large scale integration (VLSI) architectures for the 1D discrete wavelet transform
收藏 引用
Proceedings of SPIE - The International Society for Optical Engineering 1994年 2303卷 296-307页
作者: Fridman, Jose Manolakos, Elias S. Northeastern Univ. Boston MA USA
A methodology for synthesizing parallel computational structures has been applied to the Discrete wavelet Transform algorithm. It is based on linear space-time mapping with constraint driven localization. The data dep... 详细信息

Proceedings of SPIE - The International Society for Optical Engineering 1994年 2303卷 579-587页
作者: Maesumi, Mohsen Lamar Univ. Beaumont TX USA
Spectral radius of sets of matrices is a fundamental concept in studying the regularity of compactly supported wavelets. Here we review the basic properties of spectral radius and describe how to increase the efficien... 详细信息

wavelet applications in signal and image processing ii
作者: Jing, Zhenxue Zheng, Yisheng Huda, Walter Laine, Andrew F. Fan, Jian Xing, Yunong Univ. of Florida Gainesville FL USA
wavelet analysis is currently being investigated as an image enhancement tool for use in mammography. Although this approach to image processing appears to have great promise, there remain major uncertainties regardin... 详细信息
