New Models for High-Quality Surface Reconstruction and Rendering
(Kalbe, 2011-03-17)The efficient reconstruction and artifact-free visualization of surfaces from measured real-world data is an important issue in various applications, such as medical and scientific visualization, quality control, and the ... -
Optimization of Inverse Reflector Design
(Mas, 2011-03-30)<p>This thesis presents new methods for the inverse reflector design problem.We have focused on three main topics that are deeply related with theproblem: the use of real and complex light sources, the definition of ... -
Perception Based Image Editing
(Lopez-Moreno, 2011-04-08)Image editing and post-processing techniques have matured over the years, making it difficult (vergingon impossible) to assess whether an image has been digitally enhanced or modiffied somehow. However,complex manipulations ... -
Pointing Facilitation Techniques for 3D Object Selection in Virtual Environments
(Argelaguet Sanz, 2011-07-04)Selection is one of the fundamental tasks in virtual reality applications and the initial task for most common user's interactions in a virtual environment. In this thesis we analyze major factors influencing selection ... -
Privacy and Security Assessment of Biometric Template Protection
(Zhou, 2011-09-19)Biometrics enables convenient authentication based on a person s physical or behavioral characteristics. In comparisonwith knowledge- or token-based methods, it links an identity directly to its owner. Furthermore, it can ... -
Real-time GPU-accelerated Out-of-Core Rendering and Light-field Display Visualization for Improved Massive Volume Understanding
(Iglesias Guitian, Jose A., 2011-03-07)Nowadays huge digital models are becoming increasingly available for a number of different applications ranging from CAD, industrial design to medicine and natural sciences. Particularly, in the field of medicine, data ... -
Reconstructive Geometry
(Ullrich, 2011)The thesis “Reconstructive Geometry” by TORSTEN ULLRICH presents a new collision detection algorithm, a novel approach to generative modeling, and an innovative shape recognition technique. All these contributions are ... -
Symmetry in 3D Shapes - Analysis and Applications to Model Synthesis
(Bokeloh, 2011-11-29)Symmetry is an essential property of a shapes' appearance and presents a source of information for structure-aware deformation and model synthesis. This thesis proposes feature-based methods to detect symmetry and regularity ... -
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 ... -
Visual Computing in Virtual Environments
(Lancelle, 2011)This thesis covers research on new and alternative ways of interactionwith computers. Virtual Reality and multi touch setupsare discussed with a focus on three dimensional renderingand photographic applications in the field ... -
Visual Semantic Analysis to Support Semi Automatic Modeling of Service Descriptions
(Bhatti, 2011-06-10)A new trend Web service ecosystems for Service-Oriented Architectures (SOAs) and Web services is emerging. Services can be offered and traded like products in these ecosystems. The explicit formalization of services' ... -
Visual Steering to Support Decision Making in Visdom
(Waser, 2011-06-15)Computer simulation has become an ubiquitous tool to investigate the nature of systems. When steering a simulation, users modify parameters to study their impact on the simulation outcome. The ability to test alternative ... -
Visualization and Graphical Processing of Volume Data
(Gavrilescu, 2011-10-17)The extraction and visualization of information from volume data constitute important research avenues in computer graphics and imaging. The rapid development of GPUs with increasing computational power has made it possible ... -
Visually Pleasing Real-time Global Illumination Rendering for Fully-dynamic Scenes
(Dong, 2011-03-03)Global illumination (GI) rendering plays a crucial role in the photo-realistic rendering of virtual scenes. With the rapid development of graphics hardware, GI has become increasingly attractive even for real-time ...
