Plenoptic Light Transport
(2015-11-27)In this thesis we focus on the multidimensional nature of light transport as described by the plenoptic function, and in particular in the angular and temporal domains. While traditional imaging has been limited to ... -
Geometric Methods for Realistic Animation of Faces
(ETH Zurich, 2015)Realistic facial synthesis is one of the most fundamental problems in computer graphics, and has been sought after for approximately four decades. It is desired in a wide variety of fields, such as character animation ... -
Physically based rendering of synthetic objects in real environments
(Linköping University Electronic Press, 2016-12-04)This thesis presents methods for photorealistic rendering of virtual objects so that they can be seamlessly composited into images of the real world. To generate predictable and consistent results, we study physically based ... -
Interactive Physically Based Simulation — Efficient Higher-Order Elements, Multigrid Approaches and Massively Parallel Data Structures
(2015-12-07)This thesis covers interactive physically based simulation for applications such as computer games or virtual environments. Interactivity, i.e., the option that a user can influence a system, imposes challenging ... -
Printing Beyond Color: Spectral and Specular Reproduction
(2015-11-30)For accurate printing (reproduction), two important appearance attributes to consider are color and gloss. These attributes are related to two topics focused on in this dissertation: spectral reproduction and specular ... -
Exploratory Search in Time-Oriented Primary Data
(2015-11-20)In a variety of research fields, primary data that describes scientific phenomena in an original condition is obtained. Time-oriented primary data, in particular, is an indispensable data type, derived from complex ... -
Pattern Search for the Visualization of Scalar, Vector, and Line Fields
(2015-12-18)The main topic of this thesis is pattern search in data sets for the purpose of visual data analysis. By giving a reference pattern, pattern search aims to discover similar occurrences in a data set with invariance to ... -
Marker-less Motion Capture in General Scenes with Sparse Multi-camera Setups
(2015-12-09)Human motion-capture from videos is one of the fundamental problems in computer vision and computer graphics. Its applications can be found in a wide range of industries. Even with all the developments in the past years, ... -
Reinforcement learning in a Multi-agent Framework for Pedestrian Simulation
(ProQuest, 2014-10-23)This thesis proposes a new approach to pedestrian simulation based on machine learning techniques. Specifically, the work proposes the use of reinforcement learning techniques to build a decision-making modulefor pedestrian ... -
Scheduling activities under spatial and temporal constraints to populate virtual urban environments
(Université Rennes 1, 2015-07-17)Crowd simulation models usually aim at producing visually credible crowds with the intent of giving life to virtual environments. Our work focusses on generating statistically consistent behaviours that can be used to pilot ... -
Interactive Integrated Exploration and Management of Visualization Parameters
(TU Wien, 2015-07)Visualization algorithms are parameterized to offer universality in terms of handling various data types, showing different aspects of the visualized data, or producing results useful for domain experts from different ... -
Scene Reconstruction from Multi-Scale Input Data
(TU Darmstadt ULB, 2015-06-18)Geometry acquisition of real-world objects by means of 3D scanning or stereo reconstruction constitutes a very important and challenging problem in computer vision. 3D scanners and stereo algorithms usually provide geometry ... -
A Framework for Local Terrain Deformation Based on Diffusion Theory
(University of Sussex, 2015-10)Terrains have a key role in making outdoor virtual scenes believable and immersive as they form the support for every other natural element in the scene. Although important, terrains are often given limited interactivity ... -
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 ... -
Sampled and Prefiltered Anti-Aliasing on Parallel Hardware
(2015-05)A fundamental task in computer graphics is the generation of two-dimensional images. Prominent examples are the conversion of text or three-dimensional scenes to formats that can be presented on a raster display. Such a ... -
3D Reconstruction and Rendering from High Resolution Light Fields
(ETH Zurich, 2015)This thesis presents a complete processing pipeline of densely sampled, high resolution light fields, from acquisition to rendering. The key components of the pipeline include 3D scene reconstruction, geometry-driven ... -
Algorithms for User-Guided Surface Mappings
(ETH Zurich, 2015)Computing mappings between spaces is a very general problem that appears in various forms in geometry processing. They can be used to provide descriptions or representations of shapes, or place shapes in correspondence. ... -
Sampling and Variance Analysis for Monte Carlo Integration in Spherical Domain
(HAL, 2015-09)This dissertation introduces a theoretical framework to study different sampling patterns in the spherical domain and their effects in the evaluation of global illumination integrals. Evaluating illumination (light ... -
Realtime Face Tracking and Animation
(2015)Capturing and processing human geometry, appearance, and motion is at the core of computer graphics, computer vision, and human-computer interaction. The high complexity of human geometry and motion dynamics, and the high ... -
Data-driven Approaches for Interactive Appearance Editing
(2015-06-22)This thesis proposes several techniques for interactive editing of digital content and fast rendering of virtual 3D scenes. Editing of digital content - such as images or 3D scenes - is difficult, requires artistic talent ...
