3D IMAGING APPLICATIONS AT THE LISA LABORATORY DURING THE LAST 10 YEARS

This article ambitiously aims at illustrating the tremendous potential ities offered by new imaging technologies (electron microscopy, confoc al microscopy and atomic force microscopy...), that give access to eit her volumic or surfacic informations, and the necessity to create high -level tools and models that are essential for the treatment of the in formation provided by the sensors, as well from a mathematical point o f view (modeling, interpolation, correlation, reconstruction...) as un der the computing aspect (facettisation, smoothing, visualization... b ut also data structures adapted to the storage and use of voluminous f iles, parallel architectures...). Since ten years the LISA Laboratory has focused in the field of 3D imaging on the creation, development an d implementation of such theoretical and practical tools. This article briefly presents the main works on image analysis at LISA Laboratory and especially illustrates by images the main successfully addressed t hree dimensional imaging applications. The overviewed examples concern the biomedical domain (biological cells, hairs, jaws, epidermis) and that of materials (textiles, concretes, aluminium alloys).
