About me. I am a PhD candidate of the Université Clermont Auvergne, in Clermont-Ferrand, France in partnership with the ENCOV research group at the Institut Pascal and the LVIC laboratory at CEA-LIST under the supervision of Professor Adrien Bartoli and Mohamed Tamaazousti . I received my master's Degree in computer science from the EPITA in Paris, France, in 2013. My research objectives are to model the light sources to improve the rendering of augmented reality applications.
Current situation. I am looking for opportunities in Computer Graphics/Augmented+Diminished Reality/SLAM for late 2017/early 2018 in Switzerland and France (preferably Paris). You can contact me on my Linkedin or directly at morgand.alexandre_at_ gmail.com. You can find my resume here.

A Multiple-View Geometric Model of Specularities on Non-Planar Shapes with Application to Dynamic Retexturing
We propose dual JOLIMAS, a new model which raises the planarity assumption. It uses the fact that specularities remain elliptical on convex surfaces and that every surface can be divided in convex parts. The geometry of dual JOLIMAS then uses a 3D quadric per convex surface part and light source, and predicts the specularities by a means of virtual cameras, allowing it to cope with surface’s unflatness.

A Geometric Model for Specularity Prediction on Planar Surfaces with Multiple Light Sources
This paper highlights our empirical model called JOLIMAS (JOint LIght-MAterial Specularity) which is used to predict specularities in real-time on planar surfaces. We used this model to perform retexturing on several objects. The novelty of paper compared to our previous approach is the handling of multiple light sources of different intensities. Moreover, light sources can be turned on and off.

Generic and real-time detection of specular reflections in images
We proposed a real-time method for specularity prediction. The novelty of the approach was the use of a pre-treatment step to level the brightness of the image, a thresholding process according to the brightness of the image and a post-processing step which use the gradient aspect of a specularity.
