    • Passive Spatio-Temporal Geometry Reconstruction of Human Faces at Very High Fidelity 

      Beeler, Thabo (Beeler, 2012-09-18)
      The creation of realistic synthetic human faces is one of the most important and at the same time also most challenging topics in computer graphics. The high complexity of the face as well as our familiarity with it renders ...
    • Path Sampling Techniques for Efficient Light Transport Simulation 

      Georgiev, Iliyan (2015-06)
      Reproducing the interactions between light and matter in a physically accurate way can significantly improve the realistic appearance of synthetic images, however such effects can be very computationally expensive to ...
    • Path-line Oriented Visualization of Dynamical Flow Fields 

      Shi, Kuangyu (2008)
      An effective visual representation of dynamical flow behavior is still a challenging problem of modern flow visualization. Path-lines are important characteristic curves of dynamical flow fields. In this thesis, we focus ...
    • Pattern Search for the Visualization of Scalar, Vector, and Line Fields 

      Wang, Zhongjie (2015-12-18)
      The main topic of this thesis is pattern search in data sets for the purpose of visual data analysis. By giving a reference pattern, pattern search aims to discover similar occurrences in a data set with invariance to ...
    • Perception Based Image Editing 

      Lopez-Moreno, Jorge (Lopez-Moreno, 2011-04-08)
      Image editing and post-processing techniques have matured over the years, making it difficult (vergingon impossible) to assess whether an image has been digitally enhanced or modiffied somehow. However,complex manipulations ...
    • Perception-Augmenting Illumination 

      Solteszova, Veronika (Solteszova, 2012-10-04)
      At each stage of the visualization pipeline, the information is impeded by loss or by noise because of imprecise acquisition, storage limitations, and processing. Furthermore, it passes through the complex and not yet well ...
    • 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 ...
    • Perceptual Display: Exceeding Display Limitations by Exploiting the Human Visual System 

      Didyk, Piotr (Didyk, Piotr, 2012-08-20)
      Existing displays have a number of limitations, which make it difficult to realistically reproduce real-world appearance; discrete pixels are used to represent images, which are refreshed only a limited number of times ...
    • Perceptual modeling for stereoscopic 3D 

      Kellnhofer, Petr (2016-11-04)
      Virtual and Augmented Reality applications typically rely on both stereoscopic presentation and involve intensive object and observer motion. A combination of high dynamic range and stereoscopic capabilities become popular ...
    • Perceptually Driven Radiosity 

      Prikryl, Jan (Prikryl, June 2001)
      Despite its popularity among researchers the radiosity method still suffers some disadvantage over other global illumination methods. Usual implementations of the radiosity method use criteria based on radiometric values ...
    • 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 ...
    • The Personal Interaction Panel - a two-handed Interface for Augmented Reality 

      Szalavári, Zsolt (Szalavári, Sep 1999)
      Die Art und Weise, wie wir mit dem ständig wachsendem Informationsraum, der uns umgibt umgehen wird sich in den nächsten Jahren dramatisch ändern. Die Forschung auf dem Gebiet der Augmented Reality bietet eine sanfte Methode ...
    • Photon Tracing for Complex Environments 

      Wilkie, Alexander (Wilkie, April 2001)
      Qualitativ hochwertige Bildsyntheseverfahren haben im Allgemeinen das Problem, daß sie bei Anwendung auf komplexe Szenen entweder zu lange Rechenzeiten ben¨otigen, oder daß ihr Speicherplatzbedarf zu groß wird bei manchen ...
