IEEE International Symposium on Circuits and Systems (ISCAS)
作者: P. Georgiev A. Cichoki Laboratory for Advanced Brain Signal Processing Brain Science Institute RIKEN Wako Saitama Japan RIKEN Lab. for Advanced Brain Signal Processing Saitama Japan Rikagaku Kenkyujo Wako Saitama JP Brain Sci. Inst. RIKEN Wako Japan
We formulate conditions under which we can solve precisely the blind source problem (BSS) in the under-determined case (less sensors than sources), up to permutation and scaling of sources. Under these conditions, whi... 详细信息

IEEE Convention of the Electrical and ELectronic Engineers in Israel
作者: A. Shmilovici O. Maimon Department of Manufacturing Engineering Boston University Boston MA USA Department of Industrial Engineering Tel-Aviv University Tel-Aviv Israel
A reduced complexity algorithm, which is an adaptive version of the matching pursuit algorithm, is proposed for the identification of nonlinear systems. The algorithm is demonstrated on various nonlinear systems prese... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: P. Vandergheynst P. Frossard Signal Processing Laboratory Swiss Federal Institute of Technology Lausanne Switzerland
This paper presents a new image representation method based on anisotropic refinement. It has been shown that wavelets are not optimal to code 2-D objects which need true 2-D dictionaries for efficient approximation. ... 详细信息

IEEE International Conference on Image Processing
作者: H.R. Rabiee R.L. Kashyap S.R. Safavian LCC Cellular Institute Arlington VA USA Media & Interconnect Technology Lab Intel Corporation Hillsboro OR USA School of Electrical and Computer Engtineering Purdue University West Lafayette IN USA
In this paper a novel algorithm for adaptive signal expansion is presented. Here the main concern is to efficiently represent the natural images and audio signals. These signals are one or two dimensional signals with... 详细信息

IEEE International Symposium on Geoscience and Remote Sensing (IGARSS)
作者: C.M. Bachmann E.E. Clothiaux D.Q. Luong Airborne Radar Branch Radar Division Naval Research Laboratory Inc. Washington D.C. DC USA Department of Meteorology Pennsylvania State University University Park PA USA Lockheed Martin Arlington VA USA
We examine a class of constrained projection pursuit (PP) algorithms for extracting textural features from multi-spectral remote sensing imagery. Based on the assumption that spatial frequency information is useful fo... 详细信息

IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC)
作者: Depeng Yang Husheng Li Gregory D. Peterson Department of Electrical Engineering and Computer Science University of Tennessee Knoxville TN USA
A feedback structure and signal recovery algorithm, orthogonal pruning pursuit, are proposed to apply sequential compressed sensing (CS) on ultra-wideband (UWB) communications. The prior knowledge is exploited by the ... 详细信息

Annual International Conference of the IEEE Engineering in Medicine and Biology Society
作者: Antoine Picot Harry Whitmore Florian Chapotot Sleep Metabolism and Health Center University of Chicago
In this paper, an original method to detect sleep slow waves (SSW) in electroencephalogram (EEG) recordings is proposed. This method takes advantage of a Matching pursuit algorithm using a dictionary reduced to Gabor ... 详细信息
