    • LiveSync: Smart Linking of 2D and 3D Views in Medical Applications 

      Kohlmann, Peter (Kohlmann, Dec 2008)
      In dieser Dissertation werden zwei Techniken vorgestellt, welche 2D und 3DAnsichten in medizinischen Anwendungen geschickt miteinander verknüpfen.Obwohl interaktive 3D Volumenvisualisierung selbst für sehr große ...
    • Manipulations d'image expressives pour une variété de représentations visuelles - Expressive Image Manipulations for a Variety of Visual Representations 

      Bousseau, Adrien (Bousseau, 2009-10-15)
      La communication visuelle tire profit de la grande variété d'apparences qu'une image peut avoir. En ignorant les détails, les images simplifiées concentrent l'attention de l'observateur sur le contenu essentiel à transmettre. ...
    • On Visualization and Reconstruction from Non-uniform Point Sets 

      Vuçini, Erald (Vuçini, 27.11.2009)
      Technological and research advances in both acquisition and simulation devices provide continuously increasing high-resolution volumetric data that by far exceed today's graphical and display capabilities. Non-uniform ...
    • Perceptually-motivated, Interactive Rendering and Editing of Global Illumination 

      Ritschel, Tobias (Universitaet des Saarlands, 22.12.2009)
      This thesis proposes several new perceptually-motivated techniques to synthesize, edit and enhance depiction of three-dimensional virtual scenes. Finding algorithmsthat fit the perceptually economic middle ground between ...
    • Real-time Rendering and Animation of Vegetation 

      Habel, Ralf (Habel, Jan 2009)
      Vegetationsdarstellung und Animation in Echtzeitapplikationen stellen immernoch ein grosses Problem aufgrund der inhärenten Komplexität vonPanzen dar. Sowohl die geometrische Komplexität als auch der ...
    • Reconstruction and Analysis of Shapes from 3D Scans 

      Haar, Frank B. ter (Haar, 2009)
      In this thesis we use 3D laser range scans for the acquisition, reconstruction, and analysis of 3D shapes. 3D laser range scanning has proven to be a fast and effective way to capture the surface of an object in a computer. ...
    • Robust and Efficient Processing Techniques for Staticand Dynamic Geometric Data 

      Schall, Oliver (Schall, Oliver, 2009-08-28)
      Generating high quality geometric representations from real-world objects is a fundamental problem in computer graphics which is motivated bymanifold applications. They comprise image synthesis for movie productionor ...
    • SELF-DELAUNAY MESHES FOR SURFACES 

      Dyer, Ramsay (Dyer, 2010)
      In the Euclidean plane, a Delaunay triangulation can be characterized by the requirementthat the circumcircle of each triangle be empty of vertices of all other triangles. For triangulatinga surface S in R3, the Delaunay ...
    • Semantic Visualization Mapping for Volume Illustration 

      Rautek, Peter (Rautek, Dec 2008)
      DasGebiet derwissenschaftlichenVisualisierung beschäftigt sichmit der automatisiertenGenerierung von Bildern aus wissenschaftlichen Daten. Um relevanteInformationen darzustellen, werden adäquate visuelle Abstraktionen ...
    • Techniques for Stochastic ImplicitSurface Modelling and Rendering 

      Gamito, Manuel Noronha (Gamito, Sept 2009)
      Implicit surfaces are a powerful shape primitive for computer graphics. This thesis focuseson a shape modelling approach which generates synthetic shapes by the specification of animplicit surface generating function that ...
    • Template based shape processing 

      Stoll, Carsten (Stoll, Carsten, 2009-09-30)
      As computers can only represent and process discrete data, informationgathered from the real world always has to be sampled. While it isnowadays possible to sample many signals accurately and thus generatehigh-quality ...
    • Uses of uncalibrated images to enrich3D models information 

      Dellepiane, Matteo (Dellepiane, 2009)
      La diminuzione dei costi delle fotocamere digitali semi-professionali ha portato allapossibilit per tutti di acquisire immagini ad alta definizione in modo molto semplice.Tuttavia, l interpretazione di queste immagini, ...
