Presentation

LIRIS (Laboratoire d’InfoRmatique en Image et Systèmes d’information) was created in 2003 through the merging of several former laboratories involved in Communication and Information Technology research. LIRIS is affiliated to CNRS (Centre National de Recherche Scientifique) under the label UMR 5205.

The laboratory involves 280 people with 94 faculty members and researchers from INSA de Lyon, Université Claude Bernard Lyon 1, Ecole Centrale de Lyon, Université Lumière Lyon 2 and CNRS.

The laboratory is organized in two departments :

Image department : It has approximately 40 faculty members (12 professors, 28 associate professors) and 3 permanent researchers. The department incorporates five research teams. The research activities of the department cover a wide variety of methods for sensors (2D, 2D+t, 3D) data analysis, for a better understanding and for multidimensional data modeling. Hence, the research activities cover the areas of image analysis, modeling, simulation and rendering. Various data representation models are investigated, including regular grids of sensors, graphs, mesh, geometric models, procedural models, statistical or physical models. The hybridization of these models can yield to the enrichment of the representation space. The developed techniques rest on competencies of the research teams around image and signal processing, geometric modeling, algorithmic geometry, discrete geometry, topology, graphs, realistic rendering and augmented reality.

Data, Knowledge and Services (DCS) department : The DCS department is organized around five research teams involving 44 faculty members (11 professors, 33 associate professors). The research activities of the department cover a wide variety of theories, methods, and applications of information technology to the management of data, knowledge and services. It covers the following areas:

• Knowledge discovery (data mining, complex systems modeling, knowledge engineering)
• Data and services engineering (security and confidentiality, modeling, integration and querying, service composition)

The laboratory leads research on fundamental issues in these areas (image, and Data, Knowledge and services). It also investigates applications with an impact on society :

• Culture and heritage (digital libraries, critical edition, digitization of ancient documents, archiving, 3D virtual museums …)
• Ambient intelligence (pervasive systems, sensor networks, intelligent video surveillance, secured communicating objects …)
• Biology and health (data mining, complex systems modeling and analysis, e-health, …)
• Human learning (personalization, cognitive assistance, collaborative learning …)
• Digital entertainment (video games, animated cinema, multimedia data processing …)
