Graph Chatbot

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.

Heterogeneous Gossip

Rachid Guerraoui, Anne-Marie Kermarrec, Maxime Monod, Davide Frey

Gossip-based information dissemination protocols are considered easy to deploy, scalable and resilient to network dynamics. Load-balancing is inherent in these protocols as the dissemination work is evenly spread among all nodes. Yet, large-scale distribut ...

Towards Generic Detection of Unusual Events in Video Surveillance

Touradj Ebrahimi, Frédéric Dufaux, Ivan Ivanov

In this paper, we consider the challenging problem of unusual event detection in video surveillance systems. The proposed approach makes a step toward generic and automatic detection of unusual events in terms of velocity and acceleration. At first, the mo ...

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 ...

Resource allocation and adaptive scheduling for scalable video streaming

Jean-Paul Wagner

The obvious recent advances in areas such as video compression and network architectures allow for the deployment of novel video distribution applications. These have the potential to provide ubiquitous media access to end users. In recent years, applicati ...

Gossiping Capabilities

Rachid Guerraoui, Anne-Marie Kermarrec, Maxime Monod, Davide Frey

Gossip-based protocols are now acknowledged as a sound basis to implement collaborative high-bandwidth content dissemination: content location is disseminated through gossip, the actual contents being subsequently pulled. In this paper, we present HEAP, HE ...

Adaptive and robust media streaming over multiple channels with bursty losses

Pascal Frossard, Jean-Paul Wagner

This paper addresses the problem of efficiently delivering a layered media stream from multiple senders to a single receiver, over channels that present correlated packet loss patterns. Using a digital fountain approach, the performance of a distributed st ...

Adaptive media streaming over multipath networks

Dan Jurca

With the latest developments in video coding technology and fast deployment of end-user broadband internet connections, real-time media applications become increasingly interesting for both private users and businesses. However, the internet remains a best ...

Enabling Adaptive Video Streaming in P2P Systems

Pascal Frossard, Dan Jurca, Jean-Paul Wagner

Peer-to-peer (P2P) systems are becoming increasingly popular due to their ability to deliver large amounts of data at a reduced deployment cost. While P2P systems foster the development of novel media applications, they also represent an interesting altern ...

Distributed Media Rate Allocation in Overlay Networks

Pascal Frossard, Dan Jurca

We address the problem of distributed path selection and rate allocation for media streaming in overlay networks. Under the assumption that each node has only a local view of the network, we propose a distributed algorithm for joint path selection, and rat ...

Advanced virtual reality technologies for surveillance and security applications

Daniel Thalmann, Frédéric Vexo, Renaud Ott

We present a system that exploits advanced Virtual Reality technologies to create a surveillance and security system. Surveillance cameras are carried by a mini Blimp which is tele-operated using an innovative Virtual Reality interface with haptic feedback ...
