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 ..."

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 ..."
