This contribution describes a camera-based approach to fully automatically create 3D models of persons. A setup of sixteen digital cameras is used to capture the images of the person to be scanned. Using a monochromatic background and the shape-from-silhouette approach a 3D model is created automatically. Using the original images the models are(More)
A knowledge based approach for the surface reconstruction of buildings to be used in computer graphic applications is presented. Using a calibrated stereo camera pair, scene depth is estimated by correspondence analysis. To compensate for noisy and not dense depth maps we use a-priori knowledge about the scene to further increase the quality of the(More)
This contribution describes the automatic creation of highly realistic flexible 3D models of participants for distributed 3D videoconferencing systems. The proposed technique uses a flexible mesh template surrounding an interior skeleton structure, which is based on a simplified human skeleton. The vertices of this template are arranged in rigid rings along(More)
This paper describes the automated creation of a textured face mask of a natural person suitable for realtime animation. A 3D surface polygon face mask is used. A set of muscles is defined to animate the mask. The mask is adapted to a real person using 3D surface data from a calibrated stereo sensor. Firstly, the facial features of the mask are aligned to(More)
This contribution describes the creation of highly realistic 3D models of participants for distributed 3D videoconferencing systems. These models consist of a flexible triangle mesh surrounding an interior skeleton structure, which is based on a simplified human skeleton. The vertices of the predefined mesh template are arranged in rigid rings along the(More)
This contribution describes an approach towards 3D teleconferencing. Textured, 3D antropomorphic models are used in a virtual environment to give the impression of physical closeness. The requirements for such a conferencing system are on the one hand textured, articulated 3D models of the conferees. For high realism a exible deformation model has been(More)
