Epipolar image analysis is a robust method for 3D scene depth reconstruction that uses all available views of an image sequence simultaneously. It is restricted to horizontal, linear, and equidis-tant camera movements. In this paper, we present a concept for an extension of epipolar image analysis to other camera configurations like, e.g., circular(More)
In this paper we present an efficient high resolution Image Based Visual Hull (IBVH) algorithm that entirely runs in real-time on a single consumer graphics card. The target application is a real-time 3D video conferencing system. One major contribution of this paper is a novel caching strategy for the reduction of line segment intersection tests. In(More)
The interest in immersive video conference systems exists now for many years from both sides, the commercialization point of view as well as from a research perspective. Nevertheless, so far the user acceptance of such systems was still very limited. This situation changed recently. Technological advances in fields like display and camera technology as well(More)
This paper describes an approach for creating high-resolution video panoramas of large-scale sport events. In an exemplary football scenario, we used two ARRI-FLEX D-20 l~lm-style" digital cameras to capture both sides of the playing field as well as large parts of the stands. From the recorded left and right view images, we created a joint panoramic view(More)
We present an advanced disparity estimation algorithm developed for real-time immersive teleconferencing. In order to improve the disparity maps in the case of occlusions a segmentation-driven disparity post processing is applied. We introduce a novel approach for a segmentation algorithm, which uses the advantages of HSV colour space without the need of an(More)
In recent years, video communication has received a rapidly increasing interest on the market. Still unsolved is the problem of eye contact. The conferee still needs to decide whether to look into the camera or directly to the screen. Recently, a solution to this problem was presented which is based on a real-time 3D modeling of the conferees [1]. In order(More)
This paper presents a new scalable and modular high-resolution multi-projection system, which is able to support any projector type and configuration. The projected images are blended at the image borders and can be adapted photometrically and geometrically to arbitrary screen geometries. To satisfy the requirements of high quality real-time video(More)
