Bedload transport remains poorly understood partly due to the polydispersity of particles and resulting segregation. Experiments were carried out at the particle scale...

The polarimetric information is fundamentally similar for the micro-wave (radar), infrared and visible (optics) domains. However, measurement instruments vary...

Stent implantation is the most common treatment of coronary heart disease, one of the major causes of death worldwide. During a stenting procedure, the clinician...

This thesis is focused on implementation of fundamental morphological filters in the dedicated hardware. The main objective of this thesis is to provide a programmable...

Ce manuscrit présente mes contributions scientifiques de ces dix dernières années à l'interface entre traitement d'image et statistique. Il débute par l'étude d'un...

This thesis is divided into two parts. The first is devoted to the study of image restorationand the second part is devoted to the study of a Frenkel-Kontorova model...

This thesis deals with the synthesis of anisotropic volumetric textures from a single 2D observation. We present variants of non parametric and multi-scale algorithms....

In this thesis we study a nonlinear system of fractional differential equations with power nonlinearities; the solution of the system blows up in a finite time. We...

Deformable models or active contours are used for edge detection in image analysis and picture processing.<br />We purpose in this thesis, to study these models...

L'article présente le projet CAPLOC, ses objectifs et les premiers résultats obtenus à mi-projet. L’objectif du projet CAPLOC est, avant de combler les lacunes du GNSS...

This paper presents a solution to track people across a network of cameras with disjoint fields of vision. Firstly, an appearance-based signature is extracted from...

We are interested particularly in the estimation of passenger flows entering or exiting from buses. To achieve this measurement, we propose a counting system based on...

Remote sensing opens new perspectives for the study and monotoring of volcanoes. In this thesis, different approaches were discussed. optical and thermal satellite...

Global Navigation Satellite Systems (GNSS) are widely spread (with Global Positioning System - GPS) in intelligent transport systems and offer a low cost, continuous...

Colloque avec actes et comité de lecture. Internationale.

Nous proposons dans cet article une amélioration de la détection d’objets mobiles basée sur l’algorithme du Codebook par une utilisation des invariants colorimétriques...

This paper deals with dense 3D point cloud computation of urban environments around a vehicle. The idea is to use two fisheye views to get 3D coordinates of the...

Most of the Intelligent Transport Systems rely on GNSS positioning information. Unfortunately, most of their uses occur in dense urban areas where signal propagation...
