Evaluation and Enhancement of HDR Image Appearance on Displaysof Varying Dynamic Range
(Yoshida, Akiko, 2008-12-16)
The increasingly widespread availability of high dynamic range (HDR) technology has led to active study of the characteristics of the human visual system (HVS) in terms of brightness, lightness, contrast, and color ...
Capturing and Reconstructing the Appearance of Complex 3D Scenes
(Fuchs, Christian, 2009-05-29)
In this thesis, we present our research on new acquisition methods forreflectance properties of real-world objects. Specifically, we firstshow a method for acquiring spatially varying densities in volumes oftranslucent, ...
Efficient Line and Patch Feature Characterization and Management for Real-time Camera Tracking
(Wuest, 2008)
One of the key problems of augmented reality is the tracking of the camera position andviewing direction in real-time. Current vision-based systems mostly rely on the detectionand tracking of fiducial markers. Some markerless ...
Advanced Methods for Relightable Scene Representations in Image Space
(Fuchs, Martin, 2008-12-15)
The realistic reproduction of visual appearance of real-world objectsrequires accurate computer graphics models that describe the opticalinteraction of a scene with its surroundings. Data-driven approachesthat model the ...
Contours and contrast
(Smith, Kaleigh, 2008-12-11)
Contrast in photographic and computer-generated imagery communicates colour and lightness differences that would be perceived when viewing the represented scene. Due to depiction constraints, the amount of displayable ...
Accelerating the Rendering Process Using Impostors
(Jeschke, 2005)
Die Darstellung dreidimensionaler geometrischer Modelle zur Erzeugung glaubw ürdiger Bilder ist in der Computergrafik ein Gebiet von großem Interesse. Eine besondere Herausforderung ist hierbei die Erstellung einer ...
Real-Time Mono- and Multi-Volume Rendering of Large Medical Datasets on Standard PC Hardware
(Grimm, 2005)
Direkte Volumenvisualisierung ist eine effizienteMethode um komplexe Strukturen volumetrischer Datens¨atze zu untersuchen. Der Hauptvorteil, verglichen zur normalen Oberfl¨achenvisualisierung, ist die M¨oglichkeit ...
Visual Analysis of Complex Simulation Data using Multiple Heterogenous Views
(Doleisch, 2004)
Computational Fluid Dynamics (CFD) Simulationen sind in letzter Zeit in immer häufigerem Einsatz in einer Vielzahl von unterschiedlichsten Anwendungsgebieten. Die Anwendungen reichen dabei vom Einsatz in der ...
High-Quality Visualization and Filtering
(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; ...
New Acquisition Techniques for Real Objects and Light Sources in Computer Graphics
(Goesele, Michael, 2004-07-14)
Accurate representations of objects and light sources in a scenemodel are a crucial prerequisite for realistic image synthesis usingcomputer graphics techniques. This thesis presents techniques forthe efficient acquisition ...
