About me

Text in English

I am currently a Ph.D. candidate at Purdue University in the United States. My advisor is Bedrich Benes and I am a research assistant at the Computer Graphics and Visualization Lab (CGVLab). My research is about 3D reconstruction and automatic measurement of plants. More generally, I am interested in Computer Graphics, Computer Vision and Computational Optimization. During summer semesters, I usually work for industry research labs. So far, I interned at Siemens and Adobe Research. Previously, I completed a double degree at INSA Lyon in France and University of Passau in Germany.

Je suis actuellement doctorant à l'université Purdue aux Etat-Unis, supervisé par Bedrich Benes au sein du Computer Graphics and Visualization Lab (CGVLab). Je travaille principalement sur la reconstruction 3D de plantes. De manière générale, je m'intéresse à l'informatique graphique, la vision par ordinateur et l'optimisation. Pendant les vacances d'été, je fais des stages dans des laboratoires de recherche privés. Pour le moment, j'ai travaillé pour Siemens et Adobe Research. Auparavant, j'ai été diplômé du département informatique de l'INSA de Lyon en France et de l'université Passau en Allemagne.


Selected work

Sorghum 3D Reconstruction

Part of my research is about 3D reconstruction and automatic measurements of plants. The image on the right shows a voxel reconstruction of a Sorghum plant imaged at the phenotyping facility of the University of Nebraska-Lincoln. So far, I published a few papers about: 3D reconstruction, skeletonization, segmentation, leaf angle measurements. See the publications page for more details.

Terrain Viewer Widget

A turnkey Qt Widget to display a terrain in 3D. Tessellation is used to efficiently display the terrain, so that it runs in real time even on low-end hardware. A very efficient algorithm to approximate global illumination has been implemented based on this paper: Timonen, Ville, and Jan Westerholm. "Scalable Height Field Self-Shadowing."
