Adrien Bartoli has been a full Professor of Computer Science at Université d’Auvergne since fall 2009. He is currently leading the ALCoV (Advanced Laparoscopy and Computer Vision) research group jointly with Prof. Michel Canis. Previously, he was a permanent CNRS research scientist at LASMEA since fall 2004 where he led ComSee, the Computer Vision research group, together with Thierry Chateau. He was a Visiting Professor in DIKU at the University of Copenhagen between 2006-2009 and a postdoctoral researcher in the Visual Geometry Group at the University of Oxford under Prof.

After a PhD at LIMOS (UMR 6158 CNRS/Université Blaise Pascal, Clermont-Ferrand, France), I was during one year at IMATI-GE (CNR, Genoa, Italy) as a post-doctoral research associate. Since September 2010, I'm maître de conférences at the IUT GEA (Université d'Auvergne, Clermont-Ferrand), and member of ISIT.  See my personnal website for more details.

Tomographie Discrète: variantes, réductions et complexités

04/02/2010 15:00
speaker: 
Yan Gerard, ISIT, France
location: 
IUT des Cézeaux

Après un  rappel historique pour replacer la tomographie discrète dans un contexte plus général (tomographie, scanner, transformée de Radon, recherche opérationnelle...), le premier problème inverse que nous étudierons en détail sera le problème de reconstruction d'une matrice binaire avec des nombres de 1 prescrits dans chaque ligne et chaque colonne. Le sujet de l'exposé sera d'en étudier les nombreuses variantes obtenues en augmentant le nombre de projections, la dimension, le nombre de types d'atomes...

Vision in Welding

01/01/2010 15:00
speaker: 
Søren Olsen, University of Copenhagen, Danemark
location: 
3C

Welding is one of the most important industrial processes. Animportant technique within welding is (Short-Arc) V-Groove welding.Today this is domiDanemarknated by manual work.  The welder uses visionfeedback to move the electrode rod (and wire) to avoid burn through and to achieve a uniform filling; The purpose of the research is to develop a low-cost vision based control system without external illumination; Sub-tasks are seam tracking, and molten pool modelling.

Medical Image Analysis for Vascular Structures: Novel Navigation Techniques for Abdominal Catheterizations

24/11/2009 15:00
speaker: 
Martin Groher, Technische Universität München, Allemagne
location: 
3C

In modern hospitals, abdominal pathologies are often accessed by advancing a catheter through the human vessel system. A navigation based on X-ray fluoroscopy is common in such scenarios, which allows the treatment to be minimally-invasive. However, due to ambiguities in the projective images, patient motion, and radio transparency of vascular structures, this navigation is not optimal and intervention times, X-ray exposure to patient and physician, as well as the amount of administered contrast agent may increase.

Segmenting Using Complex networks

speaker: 
Jean-Charles Delvenne, Université Catholique de Louvain, Belgique

2D and 3D Shape analysis: representation, deformation, metamophosis, and symmetrization.

15/10/2009 15:00
speaker: 
Chafik Samir, ISIT, France
location: 
IUT des Cézeaux

I will describe an approach for statistical analysis of shapes of 2D boundaries (closed curves) and 3D objects (surfaces) using ideas from Riemannian geometry. A fundamental tool in this shape analysis is the construction and implementation of geodesic paths between shapes on nonlinear manifolds.
