Noise modelling in time‐of‐flight sensors with application to depth noise removal and uncertainty estimation in three‐dimensional measurement
Autor: Amira Belhedi, Adrien Bartoli, Steve Bourgeois, Vincent Gay‐Bellile, Kamel Hamrouni, Patrick Sayd
Publikováno v: IET Computer Vision, Vol 9, Iss 6, Pp 967-977 (2015)
Time‐of‐flight (TOF) sensors provide real‐time depth information at high frame‐rates. One issue with TOF sensors is the usual high level of noise (i.e. the depth measure's repeatability within a static setting). However, until now, TOF sensor

Automatic Calibration of Hybrid Dynamic Vision System for High Resolution Object Tracking
Autor: Quoc Cuong Pham, Patrick Sayd, Julie Badri, Jean-Marc Lavest, Christophe Tilmant
Publikováno v: Pattern Recognition Techniques, Technology and Applications
Visual object recognition and tracking require a good resolution of the object to accurately model its appearance. In addition, tracking systems must be able to robustly recover moving target trajectory, and possibly cope with fast motion and large d

Suivi par ré-identification dans un réseau de caméras à champs disjoints
Autor: Frédéric Lerasle, Patrick Sayd, Boris Meden
Publikováno v: Traitement du signal. 29:283-305
Cet article adresse le probleme de suivi automatique de pietons au travers de reseaux de cameras a champs de vue disjoints. Le suivi dans l'image est traite de maniere locale par un algorithme de Suivi-par-Detections et re-identification. Avec du fil

Generic and real-time structure from motion using local bundle adjustment
Autor: Patrick Sayd, Fabien Dekeyser, Michel Dhome, E. Mouragnon, Maxime Lhuillier
Publikováno v: Image and Vision Computing. 27:1178-1193
This paper describes a method for estimating the motion of a calibrated camera and the three-dimensional geometry of the filmed environment. The only data used is video input. Interest points are tracked and matched between frames at video rate. Robu

Non-parametric depth calibration of a TOF camera
Autor: Steve Bourgeois, Patrick Sayd, Kamel Hamrouni, Vincent Gay-Bellile, Amira Belhedi, Adrien Bartoli
Publikováno v: ICIP
Time-of-Flight (TOF) cameras measure, in real-time, the distance between the camera and objects in the scene. This opens new perspectives in different application fields: 3D reconstruction, Augmented Reality, video-surveillance, etc. However, like an
