Structuration physiologique de la gestuelle : modèle et tests

Modèle de graphe et modèle de langue pour la reconnaissance de scènes visuelles

We describe here a method to use a language modeling approach for image retrieval and image categorization. Since photographic images are 2D data, we first use image regions (mapped to automatically induced concepts) and then spatial relationships between these regions to build a complete image graph representation. Our method deals with different scenarios, where isolated images or groups of i...

Sur la structuration de deux systèmes complexes canards et processeurs

RÉSUMÉ. Nous montrons ici comment des méthodes analogues, basées sur des considérations très simples peuvent amener à résoudre des systèmes ou situations considérées comme complexes. Comment on passe d’une part des canards qui s’auto-organisent en vol à l’autostructuration d’un système informatique distribué. Nous rappellerons au passage comment exorciser le démon des processeurs (voir [12]). D...

Approche et modèle pour la spécification de composants-métier

Nowadays, the development components-based approach is more and more often used for the conception of information systems. In front of this expansion, it seems necessary to propose tools, models and languages dedicated to the implementation of this approach. Thus, many research works focus on the notion of “components”. Components models can be either technical (CCM, COM/DCOM, EJB) or conceptua...

Kmelia, un modèle abstrait et formel pour la description et la composition de composants et de services

Kmelia is both a language and a multi-services component-based model. The Kmelia components are abstract and formal to permit the description and the verification of properties. Within Kmelia a service may interact with its caller ; it can encapsulate other services to which it gives access and it can also require services. These services are parameterised with data and they are equipped with a...
