A Doping Bits Based BP Decoding for Rateless Distributed Source Coding Applications
Journal of Electrical and Computer Engineering, Volume 2014, Issue 1, 2014., 2014 A novel doping bits based belief propagation decoding algorithm, for rate‐adaptive LDPC codes based on fixed bipartite graph code, is proposed. The proposed work modifies the decoding algorithm, by converting the puncturing nodes to regular source nodes and by following the encoding rule at the decoder. The transmitted doping bits in place of punctured

Distributed Joint Source-Channel Coding-Based Adaptive Dynamic Network Coding
IEEE Access, 2020 Distributed Source Coding (DSC) schemes rely on separate encoding but joint decoding of statistically dependent sources, which exhibit correlation. More specifically, Distributed Joint Source-Channel coding (DJSC) is associated with the scenario, where ...

Multiple Description Coding with Side Information: Practical Scheme and Iterative Decoding
EURASIP Journal on Advances in Signal Processing, 2009 Multiple description coding (MDC) with side information (SI) at the receiver is particularly relevant for robust transmission in sensor networks where correlated data is being transmitted to a common receiver, as well as for robust video compression. The

Low‐Complexity Compression Algorithm for Hyperspectral Images Based on Distributed Source Coding
Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013 A low‐complexity compression algorithm for hyperspectral images based on distributed source coding (DSC) is proposed in this paper. The proposed distributed compression algorithm can realize both lossless and lossy compression, which is implemented by performing scalar quantization strategy on the original hyperspectral images followed by distributed ...

On the Distributed Compression of Quantum Information [PDF]
, 2005 The problem of distributed compression for correlated quantum sources is considered. The classical version of this problem was solved by Slepian and Wolf, who showed that distributed compression could take full advantage of redundancy in the local ...

Seven Challenges in Image Quality Assessment: Past, Present, and Future Research
International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 Image quality assessment (IQA) has been a topic of intense research over the last several decades. With each year comes an increasing number of new IQA algorithms, extensions of existing IQA algorithms, and applications of IQA to other disciplines. In this article, I first provide an up‐to‐date review of research in IQA, and then I highlight several ...

A Survey of Image Compression Algorithms for Visual Sensor Networks
International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 With the advent of visual sensor networks (VSNs), energy‐aware compression algorithms have gained wide attention. That is, new strategies and mechanisms for power‐efficient image compression algorithms are developed, since the application of the conventional methods is not always energy beneficial.
