In this talk, Juliàn Tachella will present his recent work on computational imaging theory and applications. On the applications side, he will introduce a new computational framework for recovering 3D point clouds in real-time from noisy and incomplete single-photon lidar measurements, and a novel non-line-of-sight imaging technique, which relies on the co-design of sensing and computation. On the theoretical side, he will present an analysis of the implicit bias of convolutional neural networks towards clean images using recent advances on the large system limit interpretation of neural networks. His analysis identifies strong links between CNN architectures and well-known signal processing techniques such as non-local means.

Bruno Levy, directeur de recherche INRIA et directeur d'INRIA Nancy Grand-Est est invité à nous parler de ses travaux en simulation de fluides et transport optimal lors d'un séminaire LIRIS le Lundi 21 Février à 14h en salle C5 du Nautibus. Abstract: I will talk about some numerical methods to simulate incompressible fluids with free boundaries. The methods I'm interested in [Gallouet & Merigot, DeGoes et. al] decompose the fluid into a set of cells (power diagram) in such a way that the volume of each cell remains constant, hence enforcing incompressibility. The volume constraints uniquely determines the parameters of the power diagram, that can be found by maximizing a concave objective function (semi-discrete optimal transport). I will show some examples of 3D fluid simulations with free boundaries, viscosity and surface tension, as well as applications in astrophysics.

Présentation des résultats du projet Européen BLISS dans le domaine de blockchain

Le 22nd workshop IRIXYS a lieu cette année à l'INSA de Lyon du 17 au 21 Juin. Ce workshop permet aux membres du centre de recherche "Hors les murs" de se regrouper tous les 6 mois pour une semaine d'échange et de reflexion scientifique autour des thèmes abordés dans le centre et à travers les présentations des doctorants. Cette édition accueille la soutenance de thèse de Hayam Mousa (DRIM)
