Développement de méthodes mathématiques pour l'analyse de trajectoires conformationnelles en dynamique moléculaire

Molecular dynamics (MD) simulations can produce nowadays huge amount of data using high-throughput CPU/GPU clusters. However, in addition not to consider the kinetic aspect of the data, the routine use of MD simulations for a study of real…

A Review of an Old Dilemma: Demosaicking First, or Denoising First?

Image denoising and demosaicking are the most important early stages in digital camera pipelines. They constitute a severely ill-posed problem that aims at reconstructing a full color image from a noisy color filter array (CFA) image. In most of the…

Débruitage vidéo et applications

This thesis studies the problem of video denoising. In the first part we focus on patch-based video denoising methods. We study in details VBM3D, a popular video denoising method, to understand the mechanisms that made its success. We also present a…

Lyapunov Functions, Identities and the Cauchy Problem for the Hele–Shaw Equation

This article is devoted to the study of the Hele-Shaw equation. We introduce an approach inspired by the water-wave theory. Starting from a reduction to the boundary, introducing the Dirichlet to Neumann operator and exploiting various cancellations…

Une exploration du déflouage d’images et vidéos : les détails qui font la différence

This thesis studies the problem of image and video blur and its removal.In the first part we focus on the restoration of image bursts, in particular for deblurring and super-resolution.First we study Fourier Burst Accumulation, which efficiently…

Classification d'événements à partir de capteurs sols - Application au suivi de personnes fragiles.

This thesis addresses the subject of event detection in temporal signals for elderly monitoring by the use of a floor pressure sensor. We first show that most proposed systems do not meet main practical issues and that floor systems constitute…

Comparaison d'images invariantes affines

Image comparison, which consists in deciding whether or not several images represent some common or similar objects, is a problem recognized as difficult, especially because of the viewpoint changes between images. The apparent deformations of…
