En temps de crise, prendre le temps

Au temps en emporte le C

Le (bon) séquencement des événements au fil du temps est un sujet important pour l’analyse de programmes, par exemple dans le cadre de protocoles d’échange d’information ou de systèmes embarqués. De nombreux travaux s’appuient sur la logique temporelle linéaire (LTL) pour décrire formellement le comportement attendu d’un programme, sous la forme d’une succession d’actions distinctes. Implanté a...

Synthèse de flux de messages en temps réel

Monitoring stream of social media posts has attracted significant attention in the last view years. Real time summarization in microblog aims at providing new relevant and non redundant information about an event as soon as it occurs. In this paper, we propose a novel continuous summarization approach in which information updates are pushed in real time. The decision to select/ignore incoming i...

Fusion de primitives visuelles pour le suivi 3D temps-réel

This paper proposes a real-time, robust and efficient 3D model-based tracking algorithm. A virtual visual servoing approach is used for monocular 3D tracking. The integration of texture information in the classical non-linear edgebased pose computation provides a more reliable tracker. Robustness is enforced using a multi-scale model of the texture and by integrating a M-estimator into the virt...

Interprétation de Mouvements Temps Réel

This paper proposes a new method for real-time human motion recognition using Motion Capture (MoCap) data. In particular, our method uses examplars to learn actions, without the need for learning intra class variations. We have formalized streamed recognizable actions, coming from an online MoCap engine, into a motion graph, similar to an animation motion graph. This graph is used as an automat...
