Animation and Performance Capture using Digitalized Models
(de Aguiar, Edilson, 2008-12-22)
The realistic generation of virtual doubles of real-world actors has been the focus of computer graphics research for many years. However, some problems still remain unsolved: it is still time-consuming to generate character ...
New 3D Scanning Techniques for Complex Scenes
(Chen, Tongbo, 2008-12-02)
This thesis presents new 3D scanning methods for complex scenes, such as surfaceswith fine-scale geometric details, translucent objects, low-albedo objects,glossy objects, scenes with interreflection, and discontinuous ...
Shape Deformations Based on Vector Fields
(Freiherr von Funck, Wolfram Alexander, 2008-12-22)
This thesis explores applications of vector field processing to shape deformations. We present a novel method to construct divergence-free vector fields which are used to deform shapes by vector field integration. ...
Efficient Shadow Map Filtering
(Annen, Thomas, 2008-12-12)
Shadows provide the human visual system with important cues to sense spatial relationshipsin the environment we live in. As such they are an indispensable partof realistic computer-generated imagery. Unfortunately, visibility ...
Learning-Based Facial Animation
(Bargmann, Robert, 2008-11-28)
This thesis proposes a novel approach for automated 3D speechanimation from audio. An end-to-end system is presented whichundergoes three principal phases. In the acquisition phase, dynamicarticulation motions are recorded ...
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 ...
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 ...
On Generalized Barycentric Coordinates and Their Applications in Geometric Modeling
(2008)
Generalized barycentric coordinate systems allow us to express the position of a
point in space with respect to a given polygon or higher dimensional polytope.
In such a system, a coordinate exists for each vertex of the ...
