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)
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)
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)
We present a new concept for the extension of epipolar image analysis to more general camera configurations like circular camera movements usually occuring for concentric mosaic acquisition. The robust method for 3D scene depth reconstruction which we call Image Cube Trajectory Analysis (ICT) is no longer restricted to horizontal, linear, and equidistant(More)
This paper details a new modular approach to virtual view creation that is designed to work in conjunction with a proposed scalable teleconferencing configuration. This scal-able system is configured using building blocks defined as Stereo Camera Analysis Blocks (SCAB). SCABs consist of axe-parallel narrow baseline stereo cameras. These provide design(More)
