Distributed compression for large camera arrays

Distributed compression for large camera arrays

引用

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, and performs centralized decoding with side information from additional views. Experimental results are given for two light field data sets. The performance of the proposed scheme is compared with independently coding each view using JPEG2000 and a shape-adaptive JPEG-like coder. The Wyner-Ziv coder yields superior compression performance at low bit-rates. In addition, there is a great reduction in encoder complexity when compared to JPEG2000.

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 algorithm is based on methods of grouping of alphabet letters suggested recently in B. Ryabko, J. Astola (2003), B. Ryabko, J. Rissanen (2003) which combines letters from a large alphabet into a small number of subsets without an essential increase of the code redundancy.

Distributed ways of communicating, processing, and sensing are replacing more traditional centralized architectures. An early example of this revolution in distributed communications is appearing in the form of sensor networks, which are densely distributed networks of embedded signal sensors, controls and processors. These nodes could be simple signal sensors, but could also be cameras and microphones. In this distributed scenario, there are several interesting topics to investigate that span from traditional signal processing problems (i.e. sampling, compression, detection) to communication and information theory (i.e. transmission protocols, capacity bounds for ad-hoc networks). This paper reviews some recent results on the topic of source representations and distributed source coding and transmission.

Wyner-Ziv coding based on TCQ and LDPC codes

Wyner-Ziv coding based on TCQ and LDPC codes

引用

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 side information Y at the decoder. Assuming ideal Slepian-Wolf coding in the sense of achieving the theoretical limit H (Q(X)|Y), it is shown that Slepian-Wolf coded TCQ (SWC-TCQ) performs 0.2 dB away from the Wyner-Ziv distortion-rate function D/sub WZ/*(R) at high rate. This result mirrors that of entropy-coded TCQ in classic source coding and establishes the connection between performances of high-rate Wyner-Ziv coding and classic source coding. Practical designs with TCQ, irregular LDPC codes (for Slepian-Wolf coding) and optimal estimation at the decoder perform 0.83 dB away from D/sub WZ/*(R) at medium bit rates (e.g., /spl ges/ 2.3 b/s). With 2-D trellis-coded vector quantization, the performance gap to D/sub WZ/*(R) is only 0.66 dB at 1.0 b/s and 0.47 dB at 3.3 b/s.

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 constructions for attaining any point on the Slepian-Wolf achievable rate region for arbitrarily correlated sources. Specifically, our prescription allows for any arbitrary memoryless joint probability distribution over any arbitrary number of distributed sources, and allows for any arbitrary rate combination that lies in the Slepian-Wolf achievable region. Special cases of our framework include the single source case (wherein our construction reduces to an entropy coder), source coding with side-information at the receiver (so-called corner points of the Slepian-Wolf region), and specific source correlation models (such as induced by a virtual binary symmetric channel model). In this work, we describe how to use low density parity check (LDPC) codes into the proposed framework to solve the general Slepian-Wolf problem constructively.

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 (RS) codes and rate-compatible punctured convolutional (RCPC) codes to protect the video data from packet loss and bit errors, respectively. Furthermore, we apply an end-to-end architecture using an edge proxy in a mobile support station to implement differential error protection for the corresponding channel impairments expected on the two networks. Results indicate that with an appropriate joint source-channel coding approach and the use of an edge proxy, FEC-based error-control techniques together with passive error-recovery techniques can significantly improve the effective video throughput and lead to acceptable video delivery quality over time-varying heterogeneous wired-to-wireless IP networks.

IEEE International Conference on Networks

ISBN: (纸本)0780377885

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 a 2-state Gilbert channel model, we compare the SNR performance of FEC with XOR operation (XOR-FEC), FEC with Reed-Solomon code (RS-FEC), side distortion optimized MDC (SD-MDC), and channel optimized MDC (optMDC). If we know the channel condition by feedback through the Real-Time Control Protocol (RTCP), optMDC can adjust the ratio between central distortion and side distortion so that it works at the best operating point. From a rate-distortion viewpoint, optMDC gives the best performance both in the single-channel and two-independent-channel transmission cases via packet networks with burst loss nature. Multiple-channel transmission is preferred if independent channels can be established between connections.

IEEE International Symposium on Information Theory

作者： A. Scaglione School of Electrical & Computer Engineering Cornell University USA

This paper discusses the compression of correlated data samples in multihop sensor network by means of distributed source coding techniques under plausible stochastic models. This paper shows that there are cases where high density sensor networks are not only possible but increased density can potentially be used to increase the precision of the measurements or decrease the transmission error. The routing algorithms and reencoding of the sensor data is proposed in this paper to provide a perfect feasible sensor networks.

National Conference on Telecommunication Technology (NCTT)

作者： M. Teow R. Tang Department of Information Technology HELP Institute Kuala Lumpur Malaysia

In the age of information and communication technology (ICT), the requirements of multimedia image transmission are essential. Image compression (source coding) has provided significant improvements for communication bandwidth, and transmission cost and data rate. The objective of the paper is to develop new techniques for strengthening the compression of still images. The features of the proposed algorithm include: (i) a wavelet transform engine, which provides a better image compression rate and visual quality as compared to DCT-based systems (JPEG); (ii) zero-path which exploits the cross-scale self-similarity of wavelet coefficients and thus provides zero-path compression; (iii) the absence of side information (significant map) for coding and decoding of zero-tree structure hence reduces the data bits for significant map symbolic coding; (iv) adaptive arithmetic entropy coding provides further compression on generating variable-length codewords. Experimental results show that the proposed algorithm outperforms both JPEG and the EZW (embedded zerotree wavelet) algorithms in terms of peak signal-to-noise ratio (PSNR), data compression bit-rate (bpp), and also human visual perception.

Data Compression Conference (DCC)

作者： Y.A. Reznik A.V. Anisimov RealNetworks Inc. Seattle WA USA Faculty of Cybernetics Kiev University Kiev Ukraine

Summary form only given. The average redundancy rate of Krichevsky's sample-based universal block codes was analyzed, in a situation wherein the samples and block codes for compression were produced from two different memoryless sources. It was proven that the average redundancy rate of adaptive block codes O/sub /spl lscr/,T/, constructed using samples of length /spl lscr/ from a source T, were used to encode block codes of length n from a source S. The adaptive block codes, constructed using samples from a source T and applied to a source S, have achieved lower average redundancy than universal codes.
