Techniques for Stochastic ImplicitSurface Modelling and Rendering
(Gamito, Sept 2009)Implicit surfaces are a powerful shape primitive for computer graphics. This thesis focuseson a shape modelling approach which generates synthetic shapes by the specification of animplicit surface generating function that ... -
Template based shape processing
(Stoll, Carsten, 2009-09-30)As computers can only represent and process discrete data, informationgathered from the real world always has to be sampled. While it isnowadays possible to sample many signals accurately and thus generatehigh-quality ... -
Temporal Coherency in Video Tone Mapping
(Boitard, 2014-10-16)One of the main goals of digital imagery is to improve the capture and the reproduction of real or synthetic scenes on display devices with restricted capabilities. Standard imagery techniques are limited with respect to ... -
Tone Mapping Techniques and Color Image Difference in Global Illumination
(Matkovic, 1997)Tone Mapping (Farbtransformation) ist der letzte Schritt eines jeden photorealistischen Bilderzeugungsverfahrens. Aufgrund der Nichtlinearit¨ aten und der vorhandenen Einschr¨ankungen des Farbraums und des dynamischen ... -
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 ... -
Topological Changes in Simulations of Deformable Objects
(Université de Strasbourg and archives-ouvertes.fr, 2017-04)Virtual cutting of deformable objects is at the core of many applications in interactive simulation and especially in computational medicine. The ability to simulate surgical cuts, soft tissue tearing or fractures, is ... -
Towards Real-Time Novel View Synthesis Using Visual Hulls
(2005)This thesis discusses fast novel view synthesis from multiple images taken from different viewpoints. We propose several new algorithms that take advantage of modern graphics hardware to create novel views. Although ... -
Tracking Hands in Action for Gesture-based Computer Input
(2016-12-16)This thesis introduces new methods for markerless tracking of the full articulated motion of hands and for informing the design of gesture-based computer input. Emerging devices such as smartwatches or virtual/augmented ... -
Tracking, Correcting and Absorbing Water Surface Waves
(2016-07-15)Computer graphics is an extremely exciting field for two reasons. On the one hand, there is a healthy injection of pragmatism coming from the visual effects industry that want robust algorithms that work so they can produce ... -
tStudy of Augmented RealityMethods for Real Time Recognitionand Tracking of Untextured 3DModels in Monocular Images
(Alvarez Ponga, dec, 2011)The main challenge of an augmented reality system is to obtain perfectalignment between real and virtual objects in order to create the illusionthat both worlds coexist. To that end, the position and orientation of theobserver ... -
Understanding the Structure of 3D Shapes: PolyCubes and Curve-Skeletons
(Livesu, 2014-05-23)Compact representations of three dimensional objects are very often usedin computer graphics to create effective ways to analyse, manipulate andtransmit 3D models. Their ability to abstract from the concrete shapes andexpose ... -
Usability Issues in Medical Volume Visualization
(König, June 2001)Eine der wichtigsten technologischen Entwicklungen im zwanzigsten Jahrhundert ist die Verwendung von Computern in vielen Bereichen des t¨aglichen Lebens, der Arbeit und der Forschung. Aufgrund der neuen M¨oglichkeiten zur ... -
The Use of Geometric Structures in Graphics and Optimization
(2015)Real-world data has a large geometric component, exhibiting significant geometric patterns. Therefore exploiting the geometric nature of data to design efficient methods has became a very important topic in several ... -
Uses of uncalibrated images to enrich3D models information
(Dellepiane, 2009)La diminuzione dei costi delle fotocamere digitali semi-professionali ha portato allapossibilit per tutti di acquisire immagini ad alta definizione in modo molto semplice.Tuttavia, l interpretazione di queste immagini, ... -
Using natural user interfaces to support learning environments
(Riunet, 2015-09-24)Education is a field of research in which Natural User Interfaces (NUI) have not been extensively exploited. NUI can help in the learning process, specially when used by children. Nowadays, children are growing up playing ... -
Viewpoint-Free Photography for Virtual Reality
(University College London, 2019-07-28)Viewpoint-free photography, i.e., interactively controlling the viewpoint of a photograph after capture, is a standing challenge. In this thesis, we investigate algorithms to enable viewpoint-free photography for virtual ... -
Virtual Endoscopy for Preoperative Planning and Training of Endonasal Transsphenoidal Pituitary Surgery
(Neubauer, June 2005)Virtual endoscopy is the navigation of a virtual camera through anatomy, computationally reconstructed from radiological data. Virtual endoscopy mimics physical minimally invasive surgical activity and is used for diagnosis ... -
Virtual Reality in Assembly Simulation - Collision Detection, Simulation Algorithms, and Interaction Techniques
(Zachmann, Gabriel, July 2000)In 1995, only a few VR systems were commercially available and a few more in the academic domain. None of these was mature at the time, nor had any of them been deployed in the field for everyday work. Some commercial and ... -
Visibility Computations for Real-Time Rendering in General 3D Environments
(Mattausch, 27.4.2010)Visibility computations are essential operations in computer graphics, which are required for rendering acceleration in the form of visibility culling, as well as for computing realistic lighting. Visibility culling, which ... -
The Visible Vortex Interactive Analysis and Extraction of Vortices in Large Time-dependent Flow
