Welcome to my personal home page.
I am currently starting a Post-doc at UCL with Dr. Niloy Mitra, to study how multi-scale geometry analysis could be combined to structural analysis to provide news tools to understand complex acquired 3D scenes. See more soon !

I have obtained my PhD under the supervision of Patrick Reuter and Christophe Schlick the December 6th 2012, at the University of Bordeaux. This work have been done in the context of the SeARCH project, which focus on the SEmi-Automatic Reassembly of Cultural Heritage.
After my PhD, I have spend 1 year working in the manao team and in collaboration with Archeovision to develop web tools for on-line repositories of Cultural Heritage content (injection, processing and visualization). This work was taking part in the European consortium v-must.
During my PhD, the main contribution of my work, in collaboration with Patrick Reuter, Pascal Barla, Gael Guennebaud and Christophe Schlick, is the the Growing Least Square framework for the analysis of oriented point-sampled manifolds at multiple scales. More details can be found here.
My major interests in Computer Graphics concern shape analysis and shape matching. More precisely, my focus concerns the study of detection of pertinent structures both in term of scale and space, in order to enforce existing algorithms (de-noising, registration, etc.). In order to provide usable techniques for acquired data (noisy, point sampled, huge models), I study GPGPU algorithms (CUDA) with efficient surface representation (e.g. Moving Least Square).
I also focus on semi-automatic approaches for object reassembly with strongly deteriorated fragments in archaeological context. The complexity of involved data requires to combining multi-scale analysis and efficient interaction techniques.
Finally, I also try to transfer as much as possible my work to industry and general public through Open source libraries (see the Screen-Space Curvature project for more details).

- Jury: Pascal Guitton (president – examiner), Pierre Alliez (reviewer), Niloy Mitra (reviewer), Andrey Sharf (examiner), Patrick Reuter (supervisor), Christophe Schlick (advisor),
- Material: see here.
- June 2012: Paper Growing Least Squares for the Analysis of Manifolds in Scale-Space accepted to Symposium Geometry Processing 2012, with Gael Guennebaud, Pascal Barla, Patrick Reuter and, Christophe Schlick (page).
- March-November 2012: Presentation of a physical reconstruction of a semi-automatic reassembly at the French National Marin Museum. Reconstructions are composed of reproductions of fragments that were acquired during the first SeARCH project step (Isis) and during a previous campaign by EDF in Alexandria. The Isis fragments have been semi-automatically aligned using our geometrical analysis, and then both fragments have been physically reproduced by neamedia (scale factor: 1/5).
