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.
