Parametric Procedural Models for 3D Object Retrieval, Classification and Parameterization
(2019-04-05)The amount of 3D objects has grown over the last decades, but we can expect that it will grow much further in the future. 3D objects are also becoming more and more accessible to non-expert users. The growing amount of ... -
Passive Spatio-Temporal Geometry Reconstruction of Human Faces at Very High Fidelity
(Beeler, 2012-09-18)The creation of realistic synthetic human faces is one of the most important and at the same time also most challenging topics in computer graphics. The high complexity of the face as well as our familiarity with it renders ... -
Path from Photorealism to Perceptual Realism
(2022-09)Photorealism in computer graphics --- rendering images that appear as realistic as photographs --- has matured to the point that it is now widely used in industry. With emerging 3D display technologies, the next big challenge ... -
Path Sampling Techniques for Efficient Light Transport Simulation
(2015-06)Reproducing the interactions between light and matter in a physically accurate way can significantly improve the realistic appearance of synthetic images, however such effects can be very computationally expensive to ... -
Path-line Oriented Visualization of Dynamical Flow Fields
(2008)An effective visual representation of dynamical flow behavior is still a challenging problem of modern flow visualization. Path-lines are important characteristic curves of dynamical flow fields. In this thesis, we focus ... -
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 ... -
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 ... -
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 ... -
Perception-Aware Computational Fabrication: Increasing The Apparent Gamut of Digital Fabrication
(Università della Svizzera italiana, 2020-10-19)Haptic and visual feedback are important for assessing objects' quality and affordance. One of the benefits of additive manufacturing is that it enables the creation of objects with personalized tactile and visual properties. ... -
Perception-inspired Tone Mapping
(Krawczyk, 2007-11-30)The display of high dynamic range images and video requires a tonemapping algorithm to depict their original appearance on existing display devices whose capabilities in terms of dynamic range are insufficient. The insightful ... -
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 ... -
Perceptual modeling for stereoscopic 3D
(2016-11-04)Virtual and Augmented Reality applications typically rely on both stereoscopic presentation and involve intensive object and observer motion. A combination of high dynamic range and stereoscopic capabilities become popular ... -
Perceptually Driven Radiosity
(Prikryl, June 2001)Despite its popularity among researchers the radiosity method still suffers some disadvantage over other global illumination methods. Usual implementations of the radiosity method use criteria based on radiometric values ... -
Perceptually-motivated, Interactive Rendering and Editing of Global Illumination
(Universitaet des Saarlands, 22.12.2009)This thesis proposes several new perceptually-motivated techniques to synthesize, edit and enhance depiction of three-dimensional virtual scenes. Finding algorithmsthat fit the perceptually economic middle ground between ... -
The Personal Interaction Panel - a two-handed Interface for Augmented Reality
(Szalavári, Sep 1999)Die Art und Weise, wie wir mit dem ständig wachsendem Informationsraum, der uns umgibt umgehen wird sich in den nächsten Jahren dramatisch ändern. Die Forschung auf dem Gebiet der Augmented Reality bietet eine sanfte Methode ... -
Photon Tracing for Complex Environments
(Wilkie, April 2001)Qualitativ hochwertige Bildsyntheseverfahren haben im Allgemeinen das Problem, daß sie bei Anwendung auf komplexe Szenen entweder zu lange Rechenzeiten ben¨otigen, oder daß ihr Speicherplatzbedarf zu groß wird bei manchen ... -
Photorealistic and Hardware Accelerated Rendering of Complex Scenes
(Hey, May 2002)Diese Arbeit präsentiert neue Methoden zur effizienten fotorealistischen und Hardware-beschleunigten Bildgenerierung von Szenen die komplexe globale Beleuchtung aufweisen, und zusätzlich auch groß sein können. Das beinhaltet ... -
Physically Based Modeling of Micro-Appearance
(University of Bonn, 2023-07-11)This dissertation addresses the challenges of creating photorealistic images by focusing on generating and rendering microscale details and irregularities, because a lack of such imperfections is usually the key aspect of ... -
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 ... -
Physics-based Reconstruction and Animation of Humans
(Ecole Polytechnique Federale de Lausanne, 2017-09-22)Creating digital representations of humans is of utmost importance for applications ranging from entertainment (video games, movies) to human-computer interaction and even psychiatrical treat- ments. What makes building ...
