      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)
      Con objeto de realizar una eficiente visualización interactiva de modelos geométricoscomplejos, que pueden llegar a comprender varios millones de polígonos, es clave reducirsustancialmente la cantidad de datos procesados. ...
    • 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 ...
    • Hybrid Methods for Interactive Shape Manipulation 

      Weber (Weber, 2010-09-12)
      Manipulating 2D and 3D shapes interactively is an important task in computer graphics. The challenge is to be able to induce a global change to the shape while preserving its local structure. A deformation tool accepts as ...
    • Illustrative Visualization of Medical Data Sets 

      Lawonn, Kai (2015-01-29)
      The aim of an illustrative visualization method is to provide a simplified representation of a complex scene or object. Concave and convex regions are emphasized and the surface complexity is reduced by omitting unnecessary ...
