L'axe Modélisation 3D & Visualisation développe des méthodes de modélisation permettant d'extraire des informations pertinentes, de représenter les données avec des formulations synthétiques génériques. Il devient alors possible de simuler et de visulaiser des objets ou des phénomènes et de corréler les résultats à la réalité.
Three dimentional reconstruction of subcutaneous tissue The aim of this project is to build a 3D geometric and mechanical model of the skin/subcutaneous complex (SSC) which could be adapted to the different parts of the body and to the morphological parameters of the patient.
Identificaiton of points of difference between shapes of human skull and monkey skullA recent pioneering applied work, in collaboration between the ICAR team and the ALGCO team, has shown that oriented matroids can be used efficiently to encode, analyze, characterize and classify shapes of 3D models given by point configurations.
Détection automatique des files cellulaires dans des images microscopiques de coupes de bois (collaboration avec AMAP/CIRAD)
The analysis of anatomical sections of wood provides important information for understanding the secondary growth and development of plants. This study reports on a new method for the automatic detection and characterization of cell les in wood images obtained by light microscopy.
Modélisation personnalisée d'un genou par recalage d'un modèle déformable sur des données 'scanner'
We developed a novel approach for simulating 3D muscle deformations with complex architectures. The approach consists in choosing the best model formulation in terms of computation cost and accuracy, that mixes a volumetric tissue model based on finite element method (3D FEM), a muscle fiber model (Hill contractile 1D element) and a membrane model accounting for aponeurosis tissue (2D FEM).
