THE VISNET II DVC CODEC: ARCHITECTURE, TOOLS AND PERFORMANCE

Touradj Ebrahimi, Frédéric Dufaux

This paper introduces the VISNET II DVC codec. This co-dec achieves very high RD performance thanks to the efficient combination of many state-of-the-art coding tools into a fully practical video codec. Experimental results show that the proposed DVC codec ...

Reconfigurable Video Coding — a Stream Programming Approach to the Specification of New Video Coding Standards

Marco Mattavelli

Current video coding standards, and their reference implementations, are architected as large monolithic and sequential algorithms, in spite of the considerable overlap of functionality between standards, and the fact that they are frequently implemented o ...

RVC-CAL dataflow implementations of MPEG AVC/H.264 CABAC decoding

Marco Mattavelli, Endri Bezati

This paper describes the implementation of the MPEG AVC CABAC entropy decoder using the RVC-CAL dataflow programming language. CABAC is the Context based Adaptive Binary Arithmetic Coding entropy decoder that is used by the MPEG AVC/H.264 main and high pro ...

Audio-based nonlinear video diffusion

Pierre Vandergheynst, Anna Llagostera Casanovas

We propose a novel non-linear video diffusion approach which is able to focus on parts of a video sequence that are relevant for applications in audio-visual analysis. The diffusion process is controlled by a diffusion coefﬁcient based on an estimate of th ...

Error-resilient Scalable Compression based on Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

Distributed Video Coding (DVC) is a new paradigm for video compression based on the information theoretical results of Slepian-Wolf (SW) and Wyner-Ziv (WZ). In this work, a performance analysis of image and video coding schemes based on DVC are presented, ...

Iterative Multiview Side Information for Enhanced Reconstruction in Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux, 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). DVC entails low complexity encoders as well as separate encoding of correlated video source ...

Multi-experts scheduling system for real-time applications

Mario Bellino

This thesis focuses on the decisional process of autonomous systems, and more particularly, on the way to take a decision when the time at disposal in order to assess the whole situation is shorter than necessary. Indeed, numerous systems propose solutions ...

Reconfigurable Video Coding : Objectives and Technologies

Marco Mattavelli, Christophe Lucarz, Ihab Mostafa Amin Mohamed Amer

The main objective of the MPEG Reconfigurable Video Coding (RVC) standard is to establish a framework for a more flexible usage of standard video coding technology. The framework not only supports multiple standards and new coding configurations, but also ...
