ANR ROOT (2016-2020)

ROOT is a project funded by the ANR throught the young researchers program JCJC. ROOT aims at developping numerical methods for solving regression problems involving optimal transport, with applications in computer graphics and vision. These problems include data fitting, supervised or unsupervised learning, or statistical inference, applied to histogram features (P.I. Nicolas Bonneel).

ANR COMEDIC (2015-2020)

The project CoMeDiC is funded by the ANR. CoMeDiC stands for Convergent Metrics for Digital Calculus. (P.I: Jacques-Olivier Lachaud)

ANR PARADIS (2018-2022)

PARameter-free Analysis of DIgital Surfaces (P.I: Tristan Roussillon)

Former Projects

ANR digitalSnow (2011-2016)

The main purpose of this project is to provide efficient computational tools to study the snow metamorphism from 3D images of real snow microstructures acquired using X-ray tomography techniques. (P.I. David Coeurjolly)
