Arthur Leclaire

Professor
in Applied Mathematics and Image Processing

Position

I joined the IMAGES team of Télécom Paris in September 2023. Before that, I was an Associate Professor at the Institut de Mathématiques de Bordeaux between 2018 and 2023, and Agrégé-préparateur at ENS Cachan (now ENS Paris-Saclay) between 2014 and 2018. I did my PhD thesis at Université Paris Descartes between 2011 and 2015, and I obtained the "Habilitation à Diriger des Recherches" (HDR) en 2023.

Research topics:

• Mathematical Image Processing
• Deep Learning, Generative Models
• Texture Modeling, Analysis and Synthesis
• Image Restoration
• Optimal Transport
• Optimization for Inverse Problems

Workshop "Advances in learning-based image restoration" (24/12/09)

Full schedule available here. This workshop is supported by RT-MAIAGES and GdR-IASIS.

Some of the workshop presentations can be downloaded here.

We would like to thank all speakers and participants of the workshop!
