  • Numerical and variational aspects of mesh parameterization and editing 

    Zayer, Rhaleb (Zayer, Rhaleb, 2007-09-17)
    A surface parameterization is a smooth one-to-one mapping between the surface and a parametric domain. Typically, surfaces with disk topology are mapped onto the plane and genus-zero surfaces onto the sphere. As any ...

  • Interactive Vegetation Rendering 

    Mantler, Stephan (Mantler, Mar 2007)
    In der Computergrafik ist die interaktive Darstellung von Pflanzen nachwie vor ein bedeutendes Problem. Deren organische Struktur besitzt oftmalseine sehr große geometrische Komplexität, die nur schlecht mit herkömmlichenVerfahren ...

  • New editing techniques for video post-processing 

    Scholz, Volker (Scholz, Volker, 2007-05-21)
    This thesis contributes to capturing 3D cloth shape, editing cloth texture and altering object shape and motion in multi-camera and monocular video recordings. We propose a technique to capture cloth shape from a 3D ...

  • Realistic Rendering and Reconstruction of Astronomical Objects and an Augmented Reality Application for Astronomy 

    Lintu, Andrei (Lintu, Andrei, 2007-12-07)
    These days, there is an ever increasing need for realistic models,renderings and visualization of astronomical objects to be used inplanetarium and as a tool in modern astrophysical research. One of themajor goals of this ...

  • Perception-inspired Tone Mapping 

    Krawczyk, Grzegorz M. (Krawczyk, 2007-11-30)
    The display of high dynamic range images and video requires a tonemapping algorithm to depict their original appearance on existing display devices whose capabilities in terms of dynamic range are insufficient. The insightful ...

  • Geometric Computing in Computer Graphics and Robotics using Conformal Geometric Algebra 

    Hildenbrand, Dietmar (Hildenbrand, Dietmar, Dec 2006)
    In computer graphics and robotics a lot of different mathematical systems like vector algebra, homogenous coordinates, quaternions or dual quaternions are used for different applications. Now it seems that a change of ...

  • Reconstruction and Rendering of Time-Varying Natural Phenomena 

    Ihrke, Ivo (Ihrke, 2007-05-21)
    While computer performance increases and computer generated images getever more realistic, the need for modeling computer graphics content is becoming stronger. To achieve photo-realism, detailed scenes have to be modeled, ...

  • Selected Quality Metrics for Digital Passport Photographs 

    Gonzalez Castillo, Oriana Yuridia (Gonzalez Castillo, 12.12.2007)
    Passbilder spielen eine wichtige Rolle bei der Identifizierung von Personen. Da die Personenerkennunggegenwärtig immer mehr an Bedeutung gewinnt und die Genauigkeit derErkennung einen großen Einfluß auf verschiedene ...

  • Methods for transform, analysis and rendering of complete light representations 

    Ahrenberg, Lukas (Ahrenberg, Lukas, 2007-07-16)
    Recent advances in digital holography, optical engineering and computer graphics have opened up the possibility of full parallax, three dimensional displays. The premises of these rendering systems are however somewhat ...
