This overview summarizes the goals of the European projects Cumuli, Panorama, and Vanguard and references the various contributions in this volume. There are several overlaps between the projects which all evolve around the geometric analysis of scenes from multiple images. All projects attempt to reconstruct the geometry and visual appearance of complex 3D scenes that may be static or dynamic. While Cumuli and Vanguard deal with images from uncalibrated cameras and unrestricted camera position for general scenes, Panorama focusses on a highly calibrated setup used to capture 3D person models. Cumuli and Vanguard developed techniques for handling multiview relations, object tracking and camera calibration, image and geometry based view synthesis, and 3D model generation. Interaction with the modeled scene and mixing of virtual and real objects leads to Virtual/Augmented Reality applications in Vanguard and Cumuli, while the Panorama approach is tuned to fully automatic scene analysis for visual communication and 3D-telepresence. Visualisation aspects are handled by Vanguard and Panorama with the development of auto-stereoscopic displays.

This paper motivates the development of stereoscopic and 3D visual communication systems for the future and it presents final research results from the European ACTS project AC092 PANORAMA (PAckage for New OpeRational Autostereoscopic Multiview systems and Applications).There is a large potential in stereoscopic and 3D visual systems for broadcast and non-broadcast applications (e.g. teleconferencing, medicine) and in the consumer entertainment market. The concept of 3D telepresence will give the viewer a better feeling of "being present in the scene" . It extends the video conferencing concept, so that participants can use nonverbal aspects of communication (eye contact, spatial perception, gestures, facial expressions) in the same way as they would in a face-to-face meeting.The objective of PANORAMA was therefore to provide new technology to overcome limitations of current video communication systems by introducing 3D telepresence. To follow this objective, 14 European partners from Universities, Research Institutes and Industry united in the PANORAMA consortium. Each PANORAMA partner is most experienced on stereoscopic and 3D imaging technologies and applications.Highlights of PANORAMA are two major demonstrator systems for video communications with 3D telepresence, and application demonstrations in the fields of medicine, stereoscopic inspection and measurement in industrial environments, and MPEG-4 scene composition for client-server applications.
