    • Symmetry in 3D Shapes - Analysis and Applications to Model Synthesis 

      Bokeloh, Martin (Bokeloh, 2011-11-29)
      Symmetry is an essential property of a shapes' appearance and presents a source of information for structure-aware deformation and model synthesis. This thesis proposes feature-based methods to detect symmetry and regularity ...
    • 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 ...
    • Temporal Coherency in Video Tone Mapping 

      Boitard, Ronan (Boitard, 2014-10-16)
      One of the main goals of digital imagery is to improve the capture and the reproduction of real or synthetic scenes on display devices with restricted capabilities. Standard imagery techniques are limited with respect to ...
    • Tone Mapping Techniques and Color Image Difference in Global Illumination 

      Matkovic, Kresimir (Matkovic, 1997)
      Tone Mapping (Farbtransformation) ist der letzte Schritt eines jeden photorealistischen Bilderzeugungsverfahrens. Aufgrund der Nichtlinearit¨ aten und der vorhandenen Einschr¨ankungen des Farbraums und des dynamischen ...
