IEEE Conference and Exhibition on Global Telecommunications (GLOBECOM)
作者: K. Zeger Department of ECE University of California La Jolla CA USA
An open problem in source coding theory has been whether the Karhunen-Loeve transform (KLT) is optimal for a system that orthogonally transforms a vector source, scalar quantizes the components of the transformed vect... 详细信息

IEEE International Symposium on Information Theory
作者: B. Ryabko J. Rissanen Siberian State University of Telecommunications and Computer Science Novosibirsk Russia Tampere International Center for Signal Technical University of Tampere Tampere Finland
We address the problem of constructing an adaptive arithmetic code in the case where the source alphabet is large and there are lots of different symbols with equal counts of occurrence. For an alphabet of N symbols a... 详细信息

IEEE International Conference on Image Processing
作者: Joohee Kim R.M. Mersereau Y. Altunbasak Center for Signal and Image Processing School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA USA
This paper presents a coordinated multiple-substream unequal error protection and error concealment algorithm for SPIHT-coded bitstreams transmitted over lossy channels. In the proposed scheme, we divide the video seq... 详细信息

IEEE International Conference on Image Processing
作者: Jen-Chang Liu Wen-Liang Hwang Wen-Jyi Hwang Institute of Information Science Nankang Taipei Taiwan Department of Electrical Engineering Chung Yuan Christian University China
Transmission of compressed images is challenging because the communication channels can be noisy and the compressed bitstreams are sensitive to channel errors. Most of the proposed methods in the literature do not gua... 详细信息

International Conference on Communications, Circuits and Systems (ICCCAS)
作者: Yingjun Su Jianhua Lu Jing Wang Department of Electronic Engineering Tsinghua University Beijing China
A global bit-allocation algorithm for wireless video communication is presented in this paper. Specifically, a generalized distortion-rate model at macroblock level is first proposed, which reflects the relation among... 详细信息

IEEE Workshop on Multimedia Signal Processing
作者: M. Gastpar P.L. Dragotti M. Vetterli Audiovisual Communications Laboratory (LCAV) Ecole Polytechnique Fédérale de Lausanne Lausanne Switzerland
The Karhunen-Loeve transform is a key element of many signal processing tasks, including classification and compression. In this paper, we consider distributed signal processing scenarios with limited communication be... 详细信息

IEEE International Symposium on Circuits and Systems (ISCAS)
作者: Hua Cai Guobin Shen Zixiang Xiong Shipeng Li Bing Zeng Department of Electrical and Electronic Engineering Hong Kong University of Science and Technology Hong Kong China Internet Media Group Microsoft Research Asia China Department of Electrical Engineering Texas A and M University USA
This paper addresses the problem of optimal packetization for a fine granularity scalable (FGS) bitstream. A very general performance metric for streaming FGS bitstreams over packet erasure networks is first defined a... 详细信息

IEEE International Symposium on Information Theory
作者: S. Jaggi M. Effros Department of Electrical Engineering California Institute of Technology Pasadena CA USA
We consider the multiple access source coding (MASC) problem (also known as the Slepian-Wolf problem) for situations where the joint source statistics are unknown a priori. Since neither encoder receives information a... 详细信息
