An efficient direct approach to visual SLAM

G Silveira, E Malis, P Rives - IEEE transactions on robotics, 2008 - ieeexplore.ieee.org
The majority of visual simultaneous localization and mapping (SLAM) approaches consider
feature correspondences as an input to the joint process of estimating the camera pose and …

Efficient homography-based tracking and 3-D reconstruction for single-viewpoint sensors

C Mei, S Benhimane, E Malis… - IEEE Transactions on …, 2008 - ieeexplore.ieee.org
This paper addresses the problem of motion estimation and 3-D reconstruction through
visual tracking with a single-viewpoint sensor and, in particular, how to generalize tracking …

Omnidirectional dense large-scale mapping and navigation based on meaningful triangulation

A Pretto, E Menegatti, E Pagello - 2011 IEEE International …, 2011 - ieeexplore.ieee.org
In this work, we propose a robust and efficient method to build dense 3D maps, using only
the images grabbed by an omnidirectional camera. The map contains exhaustive …

Issues in cooperative air/ground robotic systems

S Lacroix, G Le Besnerais - Robotics Research: The 13th International …, 2010 - Springer
The possibility to jointly deploy aerial and ground robots makes sense in many application
contexts of field robotics. There are indeed several cooperation schemes in which the …

Persuasion through overheard communication by life-like agents

SV Suzuki, S Yamada - Proceedings. IEEE/WIC/ACM …, 2004 - ieeexplore.ieee.org
It is important to investigate the influence of life-like agents interacting with a user since
some studies suggest thai life-like agents can" persuade" people, in other words, they have …

Laser-augmented omnidirectional vision for 3D localisation and mapping

C Mei - 2007 - pastel.hal.science
The problem of estimating the motion of a robot and simultaneously building a
representation of the environment (known as SLAM: Simultaneous Localisation And …

Indoor SLAM based on composite sensor mixing laser scans and omnidirectional images

G Gallegos, P Rives - 2010 IEEE International Conference on …, 2010 - ieeexplore.ieee.org
Vision sensors give mobile robots a relatively cheap means of obtaining rich 3D information
of their environment, but lack the depth information that a laser range finder can provide …

Direct visual servoing with respect to rigid objects

G Silveira, E Malis - 2007 IEEE/RSJ International Conference …, 2007 - ieeexplore.ieee.org
Existing visual servoing techniques which do not need metric information require, on the
other hand, prior knowledge about the object's shape and/or the camera's motion. In this …

Kinetics of the diffusion of some elements evaluated by neutron activation in a coral implanted in vivo

JL Irigaray, H Oudadesse, G Blondiaux… - … of radioanalytical and …, 1993 - Springer
Some studies show that a coral implanted on bone tissue is gradually transformed to
become a neoformed bone. In our work, we have, for the first time, determined quantitatively …

Optical-flow based detection of moving objects in traffic scenes

J Klappstein - 2008 - archiv.ub.uni-heidelberg.de
Traffic is increasing continuously. Nevertheless the number of traffic fatalities decreased in
the past. One reason for this are the passive safety systems, such as side crash protection or …
