Advanced Editing Methods for Image and Video Sequences
(Granados, 2013-09-10)In the context of image and video editing, this thesis proposes methods for modifying the semantic content of a recorded scene. Two different editing problems are approached: First, the removal of ghosting artifacts from ... -
Algorithms and Interfaces for Real-Time Deformation of 2D and 3D Shapes
(Jacobson, 2013-05-01)This thesis investigates computer algorithms and user interfaces which assist in the process of deforming raster images, vector graphics, geometric models and animated characters in real time. Many recent works have focused ... -
Bayesian and Quasi Monte Carlo Spherical Integration for Global Illumination
(Marques, 2013-10-22)The spherical sampling of the incident radiance function entails a high computational cost. Therefore the illumination integral must be evaluated using a limited set of samples. Such a restriction raises the question of ... -
Cache based Optimization of Stencil Computations - An Algorithmic Approach
(Shaheen, Mohammed, 2013-11-05)We are witnessing a fundamental paradigm shift in computer design. Memory has beenand is becoming more hierarchical. Clock frequency is no longer crucial for performance.The on-chip core count is doubling rapidly. The quest ... -
Computational Imaging: Combining Optics, Computation and Perception
(Masia, 2013-12-11)This thesis presents contributions on the different stages of the imaging pipeline,from capture to display, and including interaction as well; we embrace all of themunder the concept of Computational Imaging. The addressed ... -
Continuity and Interpolation Techniques for Computer Graphics
(González García, 2013)In Computer Graphics applications, it is a common practice to texture 3D models to applymaterial properties to them. Then, once the models are textured, they are deformedto create new poses that can be more appropriate for ... -
Curve Analysis with Applications to Archaeology
(Kolomenkin, 2013-09-15)In this thesis we discuss methods for the definition, detection, analysis, and application ofcurves on surfaces. While doubtlessly as important as curves in images, curves on surfacesgained less attention. A number of ... -
Data Driven Analysis of Faces from Images
(Scherbaum, Kristina, 2013-09-17)This thesis proposes three new data-driven approaches to detect, analyze, or modify faces in images. All presented contributions are inspired by the use of prior knowledge and they derive information about facial ... -
Filtering Techniques for Low-Noise Previews of Interactive Stochastic Ray Tracing
(Schwenk, 2013-07-05)Progressive stochastic ray tracing is increasingly used in interactive applications. Examples of such applications are interactive design reviews and digital content creation. This dissertation aims at advancing this ... -
Information Retrieval for Multivariate Research Data Repositories
(Scherer, 2013-12-02)In this dissertation, I tackle the challenge of information retrieval for multivariate research data by providing novel means of content-based access.Large amounts of multivariate data are produced and collected in different ... -
Interactive Multiresolution and Multiscale Visualization of Large Volume Data
(Suter, 2013-03-01)Interactive visualization and analysis of large and complex volume data is an ongoingchallenge. Data acquisition tools produce hundreds of Gigabytes of data andare one step ahead of visualization and analysis tools. ... -
Interactive Visual Analysis in Automotive Engineering Design
(Konyha, 2013-02-01)Computational simulation has become instrumental in the design process in automotive engineering. Virtually all components and subsystems of automobiles can be simulated. The simulation can be repeated many times with ... -
Of Assembling Small Sculptures and Disassembling Large Geometry
(Kerber, 2013-09-17)This thesis describes the research results and contributions that have been achieved during the author's doctoral work. It is divided into two independent parts, each of which is devoted to a particular research aspect.The ... -
The Probabilistic Active Shape Model: From Model Construction to Flexible Medical Image Segmentation
(Kirschner, 2013-07-04)Automatic processing of three-dimensional image data acquired with computed tomography or magnetic resonance imaging plays an increasingly important role in medicine. For example, the automatic segmentation of anatomical ... -
Processing and tracking human motions using optical, inertial, and depth sensors
(Helten, Thomas, 2013-12-13)The processing of human motion data constitutes an important strand of research with many applications in computer animation, sport science and medicine. Currently, there exist various systems for recording human ... -
Processing Semantically EnrichedContent for Interactive 3D Visualizations
(Settgast, 13-05-28)Interactive 3D graphics has become an essential tool in many fields of application: In manufacturingcompanies, e.g., new products are planned and tested digitally. The effect of newdesigns and testing of ergonomic aspects ... -
Reciprocal Shading for Mixed Reality
(Knecht, 2013-12-19)Reciprocal shading for mixed reality aims to integrate virtual objects into real environments in a way that they are in the ideal case indistinguishable from real objects. It is therefore an attractive technology for ... -
Reconstruction of 3D Models from Images and Point Clouds with Shape Primitives
(Reisner-Kollmann, 2013-03-12)3D models are widely used in different applications, including computer games, planning software, applications for training and simulation, and virtual city maps. For many of these applications it is necessary or at least ... -
