Uncertainty Boundaries for Complex Objects in Augmented Reality

by Jiajian Chen, Blair Macintyre
"... Registration errors between the physical world and computergenerated objects are a central problem in Augmented Reality (AR) systems. Some existing AR systems have demonstrated how to dynamically estimate registration errors based on estimates of spatial errors in the system. Using these error estim ..."

A Real-Time Tracker For Markerless Augmented Reality

by Andrew I. Comport, Eric Marchand, Francois Chaumette - In ACM/IEEE Int. Symp. on Mixed and Augmented Reality, ISMAR’03 , 2003
"... Augmented Reality has now progressed to the point where real-time applications are being considered and needed. At the same time it is important that synthetic elements are rendered and aligned in the scene in an accurate and visually acceptable way. In order to address these issues a real-time, rob ..."

Real-time markerless tracking for augmented reality: the virtual visual servoing framework

by Andrew I. Comport, Eric Marchand, Muriel Pressigout, François Chaumette - IEEE TRANS. ON VISUALIZATION AND COMPUTER GRAPHICS , 2006
"... Tracking is a very important research subject in a real-time augmented reality context. The main requirements for trackers are high accuracy and little latency at a reasonable cost. In order to address these issues, a real-time, robust, and efficient 3D modelbased tracking algorithm is proposed for ..."

Monocular model-based 3d tracking of rigid objects: A survey

by Vincent Lepetit, Pascal Fua - In Foundations and Trends in Computer Graphics and Vision , 2005
"... Many applications require tracking of complex 3D objects. These include visual servoing of robotic arms on specific target objects, Aug-mented Reality systems that require real-time registration of the object to be augmented, and head tracking systems that sophisticated inter-faces can use. Computer ..."

This paper summarizes the development of learning objects and content specifically designed for teaching dynamic 3D geometry in Augmented Reality. It concentrates on pedagogical findings while working

Augmented

by Daniela Markov-vetter, Eckard Moll, Oliver G. Staadt
"... Abstract � Future user interface technologies will shift away from conventional displays, mice and keyboards and will claim the joint use of our physical world. Augmented Reality bridges this gap by enhancing the real world with virtual information that can lead to an improved perception of our dail ..."

The use of Augmented Reality will support the space crew at handling intra-vehicular displays and control items in a natural

A semi-automatic method for resolving occlusion in augmented reality

by Vincent Lepetit, Marie-odile Berger - In Proceedings of the IEEE Conference on Computer Vision and Pattern Recognition , 2000
"... Realistic merging of virtual and real objects requires that the augmented patterns be correctly occluded by foreground objects. In this paper, we propose a semi-automatic method for resolving occlusion in augmented reality which makes use of key-views. Once the user has outlined the occluding object ..."

Fully automated and stable registration for augmented reality applications

by Vincent Lepetit, Luca Vacchetti, Daniel Thalmann, Pascal Fua, Cvlab Vrlab - In Proc. International Symposium on Mixed and Augmented Reality , 2003
"... We present a fully automated approach to camera registration for Augmented Reality systems. It relies on purely passive vision techniques to solve the initialization and realtime tracking problems, given a rough CAD model of parts of the real scene. It does not require a controlled environment, for ..."
