A method for the automatic reconstruction of 3D objects from multiple camera views for 3D multimedia applications is presented. Conventional 3D reconstruction techniques use equipment that restrict the flexibility of the user. In order to increase this flexibility, the presented method is characterized by a simple measurement environment , that consists of… (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 tex-tured 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)
As the capabilities of video standards and receiver hardware are increasing towards integrated 3d animations, generating realistic content is now becoming a limiting factor. In this paper we present a new technique of generating 3d content from reality, i.e. from video sequences acquired with normal TV cameras. The major aim is to provide the TV viewer with… (More)
1 Motivation Today many different algorithms to estimate optical flow or stereo correspondences between images are published. This makes visualization of the results in a comparable fashion an important issue. The first evaluation of an algorithm is always visually, to ensure that the estimated correspondence field approximates the intuitively expected… (More)
Das Ziel des in Niccimon realisierten persönlichen mobilen Assistenten ist es, zu jeder Zeit und an jedem Ort heterogene Informationsquellen abrufen zu können.
In this paper we propose a robust approach to register two coarse binary volume models. The presented method is based on a combination of maximising the spatial cross-correlation and an extended version of the iterative closest point algorithm (ICP). During an iterative optimisa-tion the cross-correlation. i.e. the section volume of both models, is… (More)
