Mixed reality
We have significant experience in AR that allowed good progress in building usable, reliable and robust
AR systems. Our contributions cover the entire process of AR: matching, pose initialization, 3D tracking,
in-situ modelling, handling interaction between real and virtual objects.
Medical imaging
For more than 20 years, we have been working in close collaboration with the University Hospital of Nancy and GE Healthcare in interventional neuroradiology. We have also ongoing works on realistic mitral valve simulation with surgical repair in view. Our common aim is to develop multimodality frameworks to assist therapeutic decisions and interventional gestures. Contributions of the team focus on the development of AR tools for neuro-navigation as well as the development of simulation tools for training or planning.
Experimental mechanics
In experimental solid mechanics, an important problem is to characterize properties of specimens subject to mechanical constraints, which makes it necessary to measure tiny strains. Contactless measurement techniques have emerged in the last few years and are spreading quickly. They are mainly based on images of the surface of the specimen on which a regular grid or a random speckle has been deposited. We are engaged since June 2012 in a transdisciplinary collaboration with Institut Pascal (Clermont-Ferrand Université). The aim is to characterize the metrological performances of these techniques limited by, e.g., the sensor noise, and to improve them by several dedicated image processing tools.
