In the broad field of computer vision, Three-Dimensional (3D) Human shape and body understanding has always been a hot topic. This thesis focuses on the 3D human body and its motion, with new objectives and problems arising from the growing availabil

La présente thèse s’intéresse à la relation entre diverses métriques provenant de la topologie symplectique définies sur une collection de sous-variétés lagrangiennes et la métrique de Hausdorff lorsque les sous-variétés étudiées respe

In many applications, the data can be represented by covariance matrices or correlation matrices between several signals (EEG, MEG, fMRI), physical quantities (cells, genes), or within a time window (autocorrelation). The set of covariance matrices f

We give new examples of compact, negatively curved Einstein manifolds of dimension $4$. These are seemingly the first such examples which are not locally homogeneous. Our metrics are carried by a sequence of 4-manifolds $(X_k)$ previously considered

A Brain-Computer Interface (BCI) is a system that can translate brain activity patterns into messages or commands for an interactive application. It enables a subject to send commands to a device only by means of brain activity, without requiring any

This work studies Zermelo problems on revolutions surfaces from the point of view of optimal control in the Hamiltonian framework by combining so-called geometrical and numerical methods. It is motivated by several case studies, in particular the his

Conformal geodesics are distinguished curves on a conformal manifold, loosely analogous to geodesics of Riemannian geometry. One definition of them is as solutions to a third order differential equation determined by the conformal structure. There is

Let M be a compact oriented even-dimensional manifold. This note constructs a compact symplectic manifold S of the same dimension and a map f from S to M of strictly positive degree. The construction relies on two deep results: the first is a theorem
