Comparaison et déformations de formes humaine 3D et 4D:Des invariants géometriques à l'analyse Riemannienne de formes
Autor: Pierson, E. (Emery)
Parmi les nombreuses thématiques de la vision par ordinateur, l'étude du corps humain, plus précisément l'analyse de sa forme en trois dimensions, a toujours été un sujet de grand intérêt pour ses nombreuses applications. La thèse se concent

Comparaison et déformations de formes humaine 3D et 4D: Des invariants géometriques à l'analyse Riemannienne de formes
Autor: Pierson, Emery
Publikováno v: Computer Science [cs]. Université de Lille, 2023. English. ⟨NNT : ⟩
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

Shape Analysis for Human Behavior Understanding
Autor: Drira, Hassen
Publikováno v: Library and information sciences. Université de Lille, 2020
As one of the most active research areas in computer vision, visual analysis of human motion attempts to detect, track and identify people, and more generally, to interpret human behaviors, from image sequences involving humans. The main concern of t

3D characterization of multi-segmented HPGe detectors : simulation and validation of the PSCS technique and its application for different energies with a 152 Eu source
Autor: de Canditiis, Bartolomeo
Publikováno v: Physics [physics]. Université de Strasbourg, 2020. English. ⟨NNT : 2020STRAE008⟩
New generation gamma-ray detectors arrays, such as AGATA, employ multi-segmented high purity germanium detectors in experiments of nuclear physics that require high resolution and efficiency which are obtained thanks to the application of pulse-shape

Geometric operators for 3D modeling using dictionary-based shape representations
Autor: Lescoat, Thibault
Publikováno v: Computer Vision and Pattern Recognition [cs.CV]. Institut Polytechnique de Paris, 2020. English. ⟨NNT : 2020IPPAT005⟩
In this thesis, we study high-level 3D shape representations and developed the algorithm primitives necessary to manipulate shapes represented as a composition of several parts. We first review existing representations, starting with the usual low-le

Contributions to local and non-local surface analysis
Autor: Digne, Julie
Publikováno v: Computational Geometry [cs.CG]. Université Claude Bernard Lyon 1, 2018
Following the recent progress of surface acquisition systems, geometry processing algorithms quickly evolve to deal with the variety of data types and acquisition quality. This habilitation manuscript details some recent approaches to tackle this cha
