segmentation, multimodal sensor fusion, hyperspectral imaging,

I obtained my Ph.D. in Theoretical
Computer Science in 1997 at LIP lab
of the ENS of Lyon. My initial
research field was algorithmics on
cellular automata. From 1994 to 1997,
I studied the following problem: How
to generate discrete circles in real
time by cellular automata?
I was recruited at the University Lumière - Lyon 2 as a temporary Lecturer and then, in 1998, as a Lecturer. I was first member of ERIC laboratory, then of LIRIS laboratory from 2002. My research was then oriented towards discrete geometry. The goal was the robust description of shapes by using, or redefining, the appropriate tools in the field of discrete geometry. I studied the notions of discrete tangent, discrete curvature, polygonization, segmentation into discrete arcs, etc. In this context, I obtained a "Habilitation à diriger des recherches" (in 2004) and then a full professor position in 2006.
Afterwards, my activities were gradually oriented towards the automatic analysis of images and videos. I have led several projects within this context, including the ANR project ReVeS (Reconnaissance de Végétaux sur Smartphone) in which we have developed a semi-automatic segmentation algorithm applied to tree leaves in natural environment. This work was used into the Folia App (published freely on the Apple Store), which allowed to recognize trees and shrubs from images of their leaves.
Finally, I am working in the field of deep learning applied to
images and videos since 2015. I focus
on multimodal deep learning methods using few or no
real data for object detection and
shape analysis in natural and
industrial environments. My recent
work includes deep learning
applications for plant disease
diagnosis using hyperspectral
imaging, historical image
colorization for environmental
epidemiology, and behavior analysis
in autonomous vehicles through
multimodal sensor data. I actively
collaborate across disciplines,
integrating algorithmic approaches
with real-world applications in
agriculture, geography, and environment.
