IEEE International Symposium on Circuits and Systems (ISCAS)
作者: Jung, Tae-jun Seo, Kwang-deok Jeong, Yo-won Kim, Chang Ki Yonsei Univ Wonju Gangwon South Korea Samsung Elect Corp Suwon South Korea ETRI Smart TV Media Res Team Daejeon South Korea
We propose a practical FEC code rate decision scheme based on joint source-channel distortion model. The conventional FEC code rate decision schemes using analytical source coding distortion model and channel-induced ... 详细信息

43rd Annual Allerton Conference on Communication, Control and Computing 2005
作者: Mahajan, Aditya Teneketzis, Demosthenis Department of EECS University of Michigan Ann ArborMI United States
We consider a communication system in which the outputs of a Markov source are encoded and decoded in real-time by a finite memory receiver, and the distortion measure does not tolerate delays. The objective is to cho... 详细信息

3rd International Symposium on Communications, Control, and Signal Processing (ISCCSP 2008), vol.1
作者: C. Yaacoub J. Farah B. Pesquet-Popescu Faculty of Sciences and Computer Engineering Holy Spirit University of Kaslik Jounieh Lebanon Department of Signal and Image Processing Ecole Nationale Supérieure des TéIécommunications Paris France
In this paper, we present a novel algorithm for dynamic quantization in distributed Wyner-Ziv video coding. In contrast with previous work where the quantization parameter is fixed and a feedback channel is used, our ... 详细信息

IEEE TRANSACTIONS ON IMAGE PROCESSING 2008年 第9期17卷 1654-1662页
作者: Fresia, Maria Lavagetto, Fabio Princeton Univ Dept Elect Engn Princeton NJ 08544 USA Univ Genoa Dept Commun Comp & Syst Sci I-16100 Genoa Italy
In this paper, we describe a method for fast determination of distortion-based optimal unequal error protection (UEP) of bitstreams generated by embedded image coders and transmitted over memoryless noisy channels. Th... 详细信息
