Image Authentication Using Distributed Source Coding [PDF]

open access: yesIEEE Transactions on Image Processing, 2012
We present a novel approach using distributed source coding for image authentication. The key idea is to provide a Slepian-Wolf encoded quantized image projection as authentication data. This version can be correctly decoded with the help of an authentic image as side information.

Reduced-Complexity Optimization of Distributed Quantization Using the Information Bottleneck Principle

open access: yesIEEE Open Journal of the Communications Society, 2021
This paper addresses the optimization of distributed compression in a sensor network. A direct communication among the sensors is not possible so that noisy measurements of a single relevant signal have to be locally compressed in order to meet the rate ...

Polar codes for distributed source coding [PDF]

open access: yesElectronics Letters, 2013
A polar coding method to construct a distributed source coding scheme which can achieve any point on the dominant face of the Slepian‐Wolf rate region for sources with uniform marginals is proposed.

Lattice-Based Robust Distributed Source Coding [PDF]

open access: yesIEEE Transactions on Information Theory, 2019
In this paper, we propose a lattice-based robust distributed source coding system for two correlated sources and provide a detailed performance analysis under the high resolution assumption. It is shown, among other things, that, in the asymptotic regime where 1) the side distortion approaches 0 and 2) the ratio between the central and side distortions

Repair Rates for Multiple Descriptions on Distributed Storage

open access: yesEntropy, 2022
In a traditional distributed storage system, a source can be restored perfectly when a certain subset of servers is contacted. The coding is independent of the contents of the source.

Source Modeling for Distributed Video Coding [PDF]

open access: yesIEEE Transactions on Circuits and Systems for Video Technology, 2012
This paper studies source and correlation models for Distributed Video Coding (DVC). It first considers a twostates HMM, i.e. a Gilbert-Elliott process, to model the bit-planes produced by DVC schemes. A statistical analysis shows that this model allows us to accurately capture the memory present in the video bit-planes.

Distributed Source Coding and Its Applications in Relaying-Based Transmission

open access: yesIEEE Access, 2016
Distributed source coding (DSC) schemes rely on separate encoding but joint decoding of statistically dependent sources, which exhibit correlation. DSC has numerous promising applications ranging from reduced-complexity handheld video communications to ...

Distributed Joint Source-Channel Coding in Wireless Sensor Networks

open access: yesSensors, 2009
Considering the fact that sensors are energy-limited and the wireless channel conditions in wireless sensor networks, there is an urgent need for a low-complexity coding method with high compression ratio and noise-resisted features.

Polar codes for distributed hierarchical source coding

open access: yesAdvances in Mathematics of Communications, 2015
We show that polar codes can be used to achieve the rate-distortion functions in the problem of hierarchical source coding also known as the successive refinement problem. We also analyze the distributed version of this problem, constructing a polar coding scheme that achieves the rate distortion functions for successive refinement with side ...
