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)
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)
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 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)
Image Cube Trajectory (ICT) analysis is a new and robust method to estimate the 3D structure of a scene from a set of 2D images. The motion of points in 3D space is represented by trajec-tories in an image cube. The advantage of this method is that the motion information of a single 3D point can be represented and analyzed for all available images(More)
