IEEE/SP Workshop on Statistical Signal Processing (SSP)
作者: Xiaoqing Zhu A. Aaron B. Girod Department of Electrical Engineering Information Systems Laboratory Stanford CA USA
We address the problem of compression for large camera arrays, and propose a distributed solution based on Wyner-Ziv coding. The proposed scheme allows independent encoding of each view with low-complexity cameras, an... 详细信息

IEEE International Conference on Image Processing
作者: B. Ryabko G. Mrchokov K. Egiazarian J. Astola Tampere International Center on Signal Processing Tampere University of Technology Tampere Finland
A new algorithm of the block encoding that can be implemented in such a way that block of several letters is coded using almost the same number of operations as a usual code uses for one letter is suggested. The new a... 详细信息

Asilomar Conference on Signals, Systems & Computers
作者: Yang Yang S. Cheng Zixiang Xiong Wei Zhao Department of Electrical Engineering Texas A and M University College Station TX USA Department of Computer Science Texas A and M University College Station TX USA
This paper considers TCQ and LDPC codes for the quadratic Gaussian Wyner-Ziv problem. After TCQ of the source input X, LDPC codes are used to implement Slepian-Wolf coding of the quantized source input Q(X) given the ... 详细信息

Asilomar Conference on Signals, Systems & Computers
作者: D. Schonberg S.S. Pradhan K. Ramchandran EECS Department University of California Berkeley CA USA EECS Department University of Michigan Ann Arbor MI USA
The Slepian-Wolf coding problem tackles the problem of distributed encoding of correlated discrete-alphabet sources for decoding at a common receiver. In this work, we propose distributed linear block code constructio... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: Yong Pei J.W. Modestino Electrical and Computer Engineering Department University of Miami Coral Gables FL USA
In this paper, we address the problem of enabling robust interactive video coding and transmission over heterogeneous wired-to-wireless IP networks. We propose the use of an FEC coding scheme employing Reed-Solomon (R... 详细信息

IEEE International Conference on Networks
作者: Moo Young Kim W.B. Kleijn Speech Processing Group Department Signals Sensors and Systems KTH Royal Institute of Technology Sweden
To facilitate real-time audio-visual communications through the Internet, low-delay packet-loss recovery techniques, such as forward error correction (FEC) and multiple description coding (MDC), can be used. Based on ... 详细信息
