Realistic Rendering and Reconstruction of Astronomical Objects and an Augmented Reality Application for Astronomy
(Lintu, Andrei, 2007-12-07)
These days, there is an ever increasing need for realistic models,renderings and visualization of astronomical objects to be used inplanetarium and as a tool in modern astrophysical research. One of themajor goals of this ...
Perception-inspired Tone Mapping
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 ...
Numerical and variational aspects of mesh parameterization and editing
(Zayer, Rhaleb, 2007-09-17)
A surface parameterization is a smooth one-to-one mapping between the surface and a parametric domain. Typically, surfaces with disk topology are mapped onto the plane and genus-zero surfaces onto the sphere. As any ...
New editing techniques for video post-processing
(Scholz, Volker, 2007-05-21)
This thesis contributes to capturing 3D cloth shape, editing cloth texture and altering object shape and motion in multi-camera and monocular video recordings. We propose a technique to capture cloth shape from a 3D ...
Reconstruction and Rendering of Time-Varying Natural Phenomena
While computer performance increases and computer generated images getever more realistic, the need for modeling computer graphics content is becoming stronger. To achieve photo-realism, detailed scenes have to be modeled, ...
Methods for transform, analysis and rendering of complete light representations
(Ahrenberg, Lukas, 2007-07-16)
Recent advances in digital holography, optical engineering and computer graphics have opened up the possibility of full parallax, three dimensional displays. The premises of these rendering systems are however somewhat ...
