Quelques améliorations à la segmentation d'images bayesienne
Nous détaillons dans ce rapport les différentes étapes de la segmentation Bayesienne~: modélisation, estimation, optimisation. La modélisation est appréhendée sous... -
Graph-based variational optimization and applications in computer vision
Many computer vision applications such as image filtering, segmentation and stereovision can be formulated as optimization problems. Recently discrete, convex,... -

Shape/structure/function 3D estimation in dynamic image sequences : Applicati...
In this thesis, we are interested in two complementary goals. First, we have improved the Dynamic Deformable Elastic Template (DET) model, developed at Creatis, for... -
Segmentation of 2D-echocardiographic sequences using level-set constrained wi...
The aim of this work is to propose an algorithm to segment and track the myocardium using the level-set formalism. The myocardium is first approximated by a geometric... -
Ultrasound image segmentation using local statistics with an adaptative scale...
Image segmentation is an important research area in image processing and a large number of different approaches have been developed over the last few decades. The... -
Segmentation of color and multispectral skin images
Accurate border delineation of pigmented skin lesion (PSL) images is a vital first step in computer-aided diagnosis (CAD) of melanoma. This thesis presents a novel... -
Improvement of metaheuristics for continuous optimization
Metaheuristics are general algorithmic frameworks, often nature-inspired, designed to solve complex optimization problems. Among representative metaheuristics,... -
