Overcoming Asynchrony in Audio-Visual Speech Recognition

Jean-Philippe Thiran, Virginia Estellers Casas

In this paper we propose two alternatives to overcome the natural asynchrony of modalities in Audio-Visual Speech Recognition. We first investigate the use of asynchronous statistical models based on Dynamic Bayesian Networks with different levels of async ...

Crossmodal Matching of Speakers using Lip and Voice Features in Temporally Non-overlapping Audio and Video Streams

Sébastien Marcel, Anindya Roy

Person identification using audio (speech) and visual (facial appearance, static or dynamic) modalities, either independently or jointly, is a thoroughly investigated problem in pattern recognition. In this work, we explore a novel task : person identifica ...

Attention and non-retinotopic feature integration

Michael Herzog, Thomas Otto

Features of moving objects are non-retinotopically integrated along their motion trajectories as demonstrated by a variety of recent studies. The mechanisms of non-retinotopic feature integration are largely unknown. Here, we investigated the role of atten ...

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 ...

An adaptive system for real-time scalable video streaming with end- to-end qos control

Marco Mattavelli, Daniele Renzi, Beilu Shao

This paper presents a real-time adaptive video streaming system based on the latest standardized video codec H.264/MPEG-4 AVC scalable extension (SVC). The system provides a full MPEG-21 media access framework over heterogeneous networks and terminals with ...

Energy-Aware Traffic Engineering

Dejan Kostic, Nedeljko Vasic

Energy consumption of the Internet is already substantial and it is likely to increase as operators deploy faster equipment to handle popular bandwidth-intensive services, such as streaming and video-on-demand. Existing work on energy saving considers loca ...

Continuous Query Evaluation over Distributed Sensor Networks

Karl Aberer, Sebastian Michel, Oana Anca Jurca, Alexandre Herrmann

In this paper we address the problem of processing continuous multi-join queries, over distributed data streams. Our approach makes use of existing work in the field of publish/subscribe systems. We show how these principles can be ported to our envisioned ...

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 ...

Randomized network coding for UEP video delivery in overlay networks

Pascal Frossard, Nikolaos Thomos

This paper presents a receiver-driven video delivery algorithm that exploits a novel Randomized Network Coding (RNC) scheme for unequal error protection (UEP). The main idea of our approach is to account for the unequal importance of media packets in the n ...
