Selected topics on distributed video coding

Mourad Ouaret

Distributed Video Coding (DVC) is a new paradigm for video compression based on the information theoretical results of Slepian and Wolf (SW), and Wyner and Ziv (WZ). While conventional coding has a rigid complexity allocation as most of the complex tasks a ...

Codec-Independent Scalable Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

In this paper, we introduce novel schemes for scalable Distributed Video Coding (DVC), dealing with temporal, spatial and quality scalabilities. More specifically, conventional coding is used to obtain a base layer. DVC is then applied to generate enhancem ...

Magnetic confinement fusion - Plasma heating with millimetre waves

Stefano Alberti

The need for an intense source of coherent, millimetre-wavelength radiation to heat a fusion plasma and control its instabilities represents a significant challenge in the development of the ITER experimental fusion reactor. This challenge may now have bee ...

Multiple description image coding with redundant expansions and optimal quantization

Pascal Frossard, Ivana Radulovic

This paper addresses the problem of optimal rate allocation for multiple description coding with redundant signal expansions. In case of redundant descriptions, the quantization of the transform coefficients has clearly to be adapted to the importance of t ...

Fusion-based Multiview Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

In this paper, we introduce a scheme for coding video surveillance camera networks. It is based on multiview and Distributed Video Coding (DVC). DVC is known for its low complexity encoders. This makes it very interesting for a wide range of applications, ...

Unbalanced Quantized Multi-State Video Coding

Pascal Frossard

Multi-State Video Coding (MSVC) is a multiple description scheme based on frame-wise splitting of the video sequence into two or more subsequences. Each subsequence is encoded separately to generate descriptions which can be decoded independently. Due to s ...

Fading observation alignment via feedback

Michael Christoph Gastpar

In some remote sensing applications, the functional relationship between the source being observed and the sensor readings may not be known. Because of communication constraints, this uncertainty may result in poor end-to-end distortion. If the sensors hav ...

Coding Schemes for Line Networks

Mohammad Amin Shokrollahi, Christina Fragouli

We consider a simple network, where a source and destination node are connected with a line of erasure channels. It is well known that in order to achieve the min-cut capacity, the intermediate nodes are required to process the information. We propose codi ...
