Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Rate-Distortion Curve Evaluation for Cross-Layer Optimization in Progressive Video Transmission

Laura Toni

Robust streaming of video over wireless networks poses many challenges, as coping with bandwidth variations, data losses, and heterogeneity of the receivers. Rate-distortion (RD) optimization studies are aimed at increasing the reliability of received bits ...

Special Issue on Image and Video Quality Assessment

Frédéric Dufaux, Stefan Winkler

The aim of this special issue is to provide an overview of state-of-the-art IQA/VQA methods and to address new developments towards various directions. The issue starts with an invited paper that surveys an area of great current research interest, namely N ...

Network coding of rateless video in streaming overlays

Pascal Frossard, Nikolaos Thomos

We investigate the problem of collaborative video streaming in overlay networks. We exploit path and source diversity, as well as basic processing capabilities of network nodes in order to increase the overall throughput and improve the video quality at 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, ...

Subjective assessment of H.264/AVC video sequences transmitted over a noisy channel

Touradj Ebrahimi, Francesca De Simone, Frédéric Dufaux

In this paper we describe a database containing subjective assessment scores relative to 78 video streams encoded with H.264/AVC and corrupted by simulating the transmission over error-prone network. The data has been collected from 40 subjects at the prem ...

Multiscale video applied to surveillance and video conferencing systems

David Leroux

In the following study is presented two research works: the first is concerned with the elaboration of an intelligent meeting room while the second is about the development of a real time high definition video server capable of advanced accessibility optio ...

Collaborative video streaming with Raptor network coding

Pascal Frossard, Nikolaos Thomos

We investigate the problem of collaborative video streaming with Raptor network coding over overlay networks. We exploit path and source diversity, as well as basic processing capabilities of network nodes to increase the overall throughput and improve the ...

Raptor Network Video Coding

Pascal Frossard, Nikolaos Thomos

In this paper, we consider the problem of streaming video information on lossy packet networks with path and source diversity, such as wireless mesh networks or more generally overlay architectures. We propose to distribute the video information between se ...

Joint acoustic-video fingerprinting of vehicles, part II

Volkan Cevher

In this second paper, we first show how to estimate the wheelbase length of a vehicle using line metrology in video. We then address the vehicle fingerprinting problem using vehicle silhouettes and color invariants. We combine the acoustic metrology and cl ...

Efficient error correction solutions for OFDM based digital video

Mauro Lattuada

The robustness of the delivery of digital compressed video streams has always been one of the main topic of the standardization bodies to assure the Quality of the Service (QoS). The MPEG standard which is nowadays the reference for digital television defi ...
