ohne Multiplex aufgenommen wurden mit jenen, die unser Multiplexsystem erzeugt hat. Abstract The Microsoft Kinect is a new color-depth (RGB-D) tracking device designed for home entertainment. With its great performance and low price compared to state-of-the-art depth tracking systems it is the target of a variety of academic research. We investigate the(More)
This paper presents a novel method for using programmable graphics hardware to generate fringe patterns for SLM-based holographic displays. The algorithm is designed to take the programming constraints imposed by the graphics hardware pipeline model into consideration, and scales linearly with the number of object points. In contrast to previous methods we(More)
In model-based free-viewpoint video, a detailed representation of the time-varying geometry of a real-word scene is used to generate renditions of it from novel viewpoints. In this paper, we present a method for reconstructing such a dynamic geometry model of a human actor from multi-view video. In a two-step procedure, first the spatio-temporally(More)
Space-time visual effects play an increasingly prominent role in recent motion picture productions as well as TV commercials. Currently, these effects must be meticulously planned before extensive, specialized camera equipment can be precisely positioned and aligned at the set; once recorded, the effect cannot be altered or edited anymore. In this paper, we(More)
— In recent years, the convergence of computer vision and computer graphics has put forth free-viewpoint video as a new field of research. The goal is to advance traditional 2D video into an immersive medium that enables the viewer to interactively choose an arbitrary viewpoint in 3D space onto the a scene while it plays back. In this paper we give an(More)
1 We present a method to analytically compute the light distribution of triangles directly in frequency space. This allows for fast evaluation, shading and propagation of light from 3D mesh objects using angular spectrum methods. The algorithm complexity is only dependant on the hologram resolution and the polygon count of the 3D model. In contrast to other(More)
Many algorithms require vector algebra operations such as the dot product, vector norms or component-wise manipulations. Especially for large-scale vectors, the efficiency of algorithms depends on an efficient implementation of those calculations. The calculation of vector operations benefits from the continually increasing chip level parallelism on(More)
Eye gaze can be a rich source of information to identify particular interests of human users. Eye gaze tracking has been largely used in different research areas in the last years, as for example in psychology, visual system design and to leverage the user interaction with computer systems. In this paper, we present an IR-based gaze tracking framework that(More)
This paper presents an extension to optical flow-based motion estimation using alternating short- and long-exposed images. While traditional optical flow algorithms rely on consecutive short-exposed images only, long-exposed images capture motion directly in the form of motion blur. This additional information can be used to achieve more robust and accurate(More)
