RESEARCH TOPICS
I am interested in various topics related to image and human vision.
During my PhD, mathematical morphology was used as a smart
tool in order to simulate hydrodynamic flows. The practical application was the design of ceramic filters.
Then, at the LCPC (now IFSTTAR), I have considered the images from the human point of view. My first goal was to propose realistic Computer Graphics
images: the observer's experience should be the same looking at the images as in the
real world. I have explored two varieties of realism: physical realism,
trying to simulate the physics of lighting in virtual environments, and
perceptual realism, trying to produce the same percepts as should have
happened in the simulated environment. The purpose of these
researches was to use Computer Graphics images to assess road visibility, and thus to improve road safety. Thus, both computer graphics developments and evaluation have been considered.
More
recently, I proposed a more pluri-disciplinary approach for road
visibility. Starting from academic knowledge in vision science, I try
to include some of this knowledge into road infrastructure design and
evaluation. Applications to road lighting, photometry, computer vision,
traffic simulation and driving simulation are included so far. This
approach also led to some investigations in cognitive psychology, trying
to understand what people look at, when driving.
