Perception-Augmenting Illumination
(Solteszova, 2012-10-04)At each stage of the visualization pipeline, the information is impeded by loss or by noise because of imprecise acquisition, storage limitations, and processing. Furthermore, it passes through the complex and not yet well ... -
Non-Periodic Corner Tilingsin Computer Graphics
(Schlömer, 2012-11-16)Rendering computer-generated images is both memory and runtime intensive.This is particularly true in realtime computer graphics where large amounts ofcontent have to be produced very quickly and from limited data. ... -
Algorithms for 3D Isometric Shape Correspondence - Algorithms for 3D Isometric Shape Correspondence
(Sahillioglu, 2012-08-01)There are many pairs of objects in the digital world that need to be related before performing any comparison, transfer, or analysis in between. The shape correspondence algorithms essentially address this problem by taking ... -
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 ... -
Real-Time Geometry Decompression on Graphics Hardware
(Dr. Hut Verlag, 2012-08-01)Real-Time Computer Graphics focuses on generating images fast enough to cause the illusion of a continuous motion. It is used in science, engineering, computer games, image processing, and design. Special purpose graphics ... -
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 ... -
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 ... -
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 ... -
Meshless sampling and reconstruction of manifolds and patterns
(Öztireli, 2013)It is one of the main goals of Computer Graphics in particular, and science ingeneral, to understand and mimic the complexity in the real world. Over the pastdecades, it has been proven that the mathematical structures of ... -
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 ... -
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 ... -
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 ... -
Automated methods for audio-based music analysis with applications to musicology
(Konz, 2012-11-09)This thesis contributes to bridging the gap between music information retrieval (MIR) and musicology. We present several automated methods for music analysis, which are motivated by concrete application scenarios being of ... -
Practical Real-Time Strategies for Photorealistic Skin Rendering and Antialiasing
(Jimenez, 2012-07-13)The first topic of this thesis, photorealistic skin rendering, is of extreme importance to create believable special effects in cinematography,but it has been ignored to an extent by the game industry. However, in the last ... -
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 ... -
Signal processing methods for beat tracking, music segmentation, and audio retrieval
(Grosche, Peter, 2012-11-09)The goal of music information retrieval (MIR) is to develop novel strategies and techniques for organizing, exploring, accessing, and understanding music data in an efficient manner. The conversion of waveform-based ... -
Non-Uniform Deformable Volumetric Objects for Medical Organ Segmentation and Registration
(Erdt, 2012-06-13)In medical imaging, large amounts of data are created during each patient examination, especially using 3-dimensional image acquisition techniques such as Computed Tomography. This data becomes more and more difficult to ... -
Perceptual Display: Exceeding Display Limitations by Exploiting the Human Visual System
(Didyk, Piotr, 2012-08-20)Existing displays have a number of limitations, which make it difficult to realistically reproduce real-world appearance; discrete pixels are used to represent images, which are refreshed only a limited number of times ... -
Quadrilateral Surface Mesh Generationfor Animation and Simulation
(Bommes, 2012-10-11)Accurately describing the geometry of objects in a digital environment, i.e. computers, isan essential ingredient in many of nowadays applications. Often it is desired to forecastthe behavior of real phenomena which depend ... -
A Frequency Analysis of Light Transport: from Theory to Implementation
(Belcour, 2012-10-30)The simulation of complex light effects such as depth-of-field, motionblur or scattering in participating media requires a tremendous amountof computation. But the resulting pictures are often blurry. We claimthat those ...
