Marker tracking and HMD calibration for a video-based augmented reality conferencing system

by Hirokazu Kato - in The 2nd International Workshop on Augmented Reality (IWAR 99 , 1999
"... We describe an augmented reality conferencing system which uses the overlay of virtual images on the real world. Remote collaborators are represented on Virtual Monitors which can be freely positioned about a user in space. Users can collaboratively view and interact with virtual objects using a sha ..."

Image-based visual hulls

by Wojciech Matusik, Chris Buehler, Ramesh Raskar, Steven J. Gortler, Leonard McMillan - IN PROCEEDINGS OF ACM SIGGRAPH 2000 , 2000
"... In this paper, we describe an efficient image-based approach to computing and shading visual hulls from silhouette image data. Our algorithm takes advantage of epipolar geometry and incremental computation to achieve a constant rendering cost per rendered pixel. It does not suffer from the computati ..."

the computation complexity, limited resolution, or quantization artifacts of previous volumetric approaches. We demonstrate the use of this algorithm in a real-time virtualized reality application running off a small number of video streams.

Image Mosaicing for Tele-Reality Applications

by Richard Szeliski , 1994
"... While a large number of virtual reality applications, such as fluid flow analysis and molecular modeling, deal with simulated data, many newer applications attempt to recreate true reality as convincingly as possible. Building detailed models for such applications, which we call tele-reality, is a m ..."

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 ..."

for a “video see through ” monocular vision system. The tracking of objects in the scene amounts to calculating the pose between the camera and the objects. Virtual objects can then be projected into the scene using the pose. Here, nonlinear pose estimation is formulated by means of a virtual visual

Virtual Museums and Virtual Realities

Virtualized Reality: Concepts and Early Results

by Takeo Kanade, P. J. Narayanan, Peter W. Rander - IN PROC. OF IEEE WORKSHOP ON THE REPRESENTATION ON VISUAL SCENE , 1995
"... The visual medium evolved from early paintings to the realistic paintings of the classical era to photographs. The medium of moving imagery started with motion pictures. Television and video recording advanced it to show action “live” or capture and playback later. In all of the above media, the vie ..."

, the view of the scene is determined at the transcription time, independent of the viewer. We have been developing a new visual medium called virtualized reality. It delays the selection of the viewing angle till view time, using techniques from computer vision and computer graphics. The visual event

Calibration-free augmented reality

by Kiriakos N. Kutulakos, James R. Vallino, Student Member - IEEE Transactions on Visualization and Computer Graphics , 1998

Abstract—Camera calibration and the acquisition of Euclidean 3D measurements have so far been considered necessary requirements for overlaying three-dimensional graphical objects with live video. In this article, we describe a new approach to videobased augmented reality that avoids both requirement ..."
