      Gryaditskaya, Yulia (2017-06-02)
      Two-dimensional, conventional images are gradually losing their hegemony, leaving room for novel formats. Among these, 8 bit images give place to high dynamic range (HDR) image formats, allowing to improve colour gamut and ...
    • High Quality Dynamic Reflectance and Surface Reconstruction from Video 

      Ahmed, Naveed (Ahmed, Naveed, 2009-07-10)
      The creation of high quality animations of real-world human actors has long been a challenging problem in computer graphics. It involves the modeling of the shape of the virtual actors, creating their motion, and the ...
    • High-Fidelity Imaging 

      Mantiuk, Rafal (Mantiuk, Rafal, 2006-12-14)
      As new displays and cameras offer enhanced color capabilities, thereis a need to extend the precision of digital content. High DynamicRange (HDR) imaging encodes images and video with higher than normalbit-depth precision, ...
    • High-quality Face Capture, Animation and Editing from Monocular Video 

      Garrido, Pablo (2017-06-26)
      Digitization of virtual faces in movies requires complex capture setups and extensive manual work to produce superb animations and video-realistic editing. This thesis pushes the boundaries of the digitization pipeline by ...
    • High-Quality Real-Time Global Illumination in Augmented Reality 

      Kan, Peter (Kan, 2014-08-22)
      High-quality image synthesis, indistinguishable from reality, has been one of the most important problems in computer graphics from its beginning. Image synthesis in augmented reality (AR) poses an even more challenging ...
    • High-Quality Visualization and Filtering 

      Hadwiger, Markus (Hadwiger, 2004)
      Die meisten Renderingmethoden in der Visualisierung und Computergraphik konzentrieren sich entweder auf die Bildqualität; und generieren <i>korrekte</i> Bilder mit nicht mehr interaktiven Bildraten; ...
    • HLOD Refinement Driven by Hardware Occlusion Queries 

      Charalambos, Jean Pierre (Charalambos, Dec 2007)

    • Homogenizing Yarn Simulations: Large-scale mechanics, small-scale detail, and quantitative fitting 

      Sperl, Georg (Institute of Science and Technology Austria, 2022-09-09)
      The complex yarn structure of knitted and woven fabrics gives rise to both a mechanical and visual complexity. The small-scale interactions of yarns colliding with and pulling on each other result in drastically different ...
    • Human Visual System Models in Computer Graphics 

      Aydin, Tunc Ozan (Tunc Ozan Aydin, 2011-10-11)
      At the receiving end of visual data are humans; thus it is only natural to takeinto account various properties and limitations of the human visual system whiledesigning new image and video processing methods. In this ...
