Real-time Illustrative Visualization of Cardiovascular Hemodynamics
(Van Pelt, 13-06-2012)
Modern magnetic resonance imaging techniques enable acquisition of time-resolved volumetric blood-flow velocity data. With these data, physicians aim for newfound insight into the intricate blood-flow dynamics. This ...
Intrinsic image decomposition from multiple photographs
(Laffont Pierre-Yves, 2012-10-12)
Editing materials and lighting is a common image manipulation task that requires significantexpertise to achieve plausible results. Each pixel aggregates the effect of both materialand lighting, therefore standard color ...
Passive Spatio-Temporal Geometry Reconstruction of Human Faces at Very High Fidelity
(Beeler, 2012-09-18)
The creation of realistic synthetic human faces is one of the most important and at the same time also most challenging topics in computer graphics. The high complexity of the face as well as our familiarity with it renders ...
Topological analysis of discrete scalar data
(Günther, 2012-12-18)
This thesis presents a novel computational framework that allows for a robust extraction and quantification of the Morse-Smale complex of a scalar field given on a 2- or 3- dimensional manifold. The proposed framework is ...
Colour videos with depth: acquisition, processing and evaluation
(Richardt, 2012-02-21)
<p>The human visual system lets us perceive the world around us in three dimensions by integrating evidence from depth cues into a coherent visual model of the world. The equivalent in computer vision and computer ...
Optimization Techniques For ComputationallyExpens Ive Rendering Algorithms
(Navarro Gil, 2012-04-01)
This thesis focuses on a group of rendering methods known by their high computational requirements. We analyse them in detail and reduce their cost using a set of conceptually different approaches.We first focus on rendering ...
From irregular meshes to structured models
(Panozzo, 2012-05-07)
Surface manipulation and representation is becoming increasingly important, with applications ranging from special effects for films and video-games to physical simulation on the hulls of airplanes. Much research has been ...
Computergraphics and Nature
(Neubert, 2012-05-07)
<p>This thesis presents new methods for modeling and efficient rendering of botanical scenes and objects. The first methodallows for producing 3D tree models from a set of images with limited user intervention by ...
The Intrinsic Shape of Point Clouds
(Ohrhallinger, 2012-07-12)
Given a point cloud, in the form of unorganized points, the problem of automatically connecting the dots to obtain an aesthetically pleasing and piecewise-linear closed interpolating boundary shape has been extensively ...
