Nearly Recurrent Components in 3D Piecewise Constant Vector Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present an algorithm for computing nearly recurrent components, that represent areas of close to circulating or stagnant flow, for 3D piecewise constant (PC) vector fields defined on regular grids. Using a number of ... -
New Bounds on the Size of Optimal Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2012)The theory of optimal size meshes gives a method for analyzing the output size (number of simplices) of a Delaunay refinement mesh in terms of the integral of a sizing function over the input domain. The input points define ... -

Nonrigid Matching of Undersampled Shapes via Medial Diffusion
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We introduce medial diffusion for the matching of undersampled shapes undergoing a nonrigid deformation. We construct a diffusion process with respect to the medial axis of a shape, and use the quantity of heat diffusion ... -
NoRM: No-Reference Image Quality Metric for Realistic Image Synthesis
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Synthetically generating images and video frames of complex 3D scenes using some photo-realistic rendering software is often prone to artifacts and requires expert knowledge to tune the parameters. The manual work required ... -
Novel-View Synthesis of Outdoor Sport Events Using an Adaptive View-Dependent Geometry
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose a novel fully automatic method for novel-viewpoint synthesis. Our method robustly handles multicamera setups featuring wide-baselines in an uncontrolled environment. In a first step, robust and sparse point ... -
Parallel Blue-noise Sampling by Constrained Farthest Point Optimization
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We describe a fast sampling algorithm for generating uniformly-distributed point patterns with good blue noise characteristics. The method, based on constrained farthest point optimization, is provably optimal and may be ... -
Parallel Computation of 3D Morse-Smale Complexes
(The Eurographics Association and Blackwell Publishing Ltd., 2012)The Morse-Smale complex is a topological structure that captures the behavior of the gradient of a scalar function on a manifold. This paper discusses scalable techniques to compute the Morse-Smale complex of scalar functions ... -
Parallel Surface Reconstruction for Particle-Based Fluids
(The Eurographics Association and Blackwell Publishing Ltd., 2012)This paper presents a novel method that improves the efficiency of high‐quality surface reconstructions for particle-based fluids using Marching Cubes. By constructing the scalar field only in a narrow band around the ... -
Parameterization-Aware MIP-Mapping
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a method of generating mipmaps that takes into account the distortions due to the parameterization of a surface. Existing algorithms for generating mipmaps assume that the texture is isometrically mapped to the ... -
Per-Vertex Defocus Blur for Stochastic Rasterization
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present user-controllable and plausible defocus blur for a stochastic rasterizer. We modify circle of confusion coefficients per vertex to express more general defocus blur, and show how the method can be applied to ... -
Perception of Animated Node-Link Diagrams for Dynamic Graphs
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Effective visualization of dynamic graphs remains an open research topic, and many state-of-the-art tools use animated node-link diagrams for this purpose. Despite its intuitiveness, the effectiveness of animation in ... -
Perceptually Linear Parameter Variations
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Most visual analysis tasks require interactive adjustment of parameter values. In general, a linear variation of a parameter, using for instance a GUI slider, changes the visual result in a perceptually non-linear way. ... -
Perceptually Optimized Coded Apertures for Defocus Deblurring
(The Eurographics Association and Blackwell Publishing Ltd., 2012)The field of computational photography, and in particular the design and implementation of coded apertures, has yielded impressive results in the last years. In this paper we introduce perceptually optimized coded apertures ... -
Performance Capture of High-Speed Motion Using Staggered Multi-View Recording
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a markerless performance capture system that can acquire the motion and the texture of human actors performing fast movements using only commodity hardware. To this end we introduce two novel concepts: First, a ... -
Pixel Art with Refracted Light by Rearrangeable Sticks
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Pixel art is a kind of digital art that through per-pixel manipulation enables production of a diverse array of artistic images. In this paper, we present a new way for people to experience and express pixel art. Our digital ... -
Polynomial Optics: A Construction Kit for Efficient Ray-Tracing of Lens Systems
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Simulation of light transport through lens systems plays an important role in graphics. While basic imaging properties can be conveniently derived from linear models (like ABCD matrices), these approximations fail to ... -
PORGY: A Visual Graph Rewriting Environment for Complex Systems
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Graph rewriting systems (GRSs) operate on graphs by substituting local patterns according to a set of rewriting rules. The apparent simplicity of GRSs hides an incredible complexity and turns the study of these systems ... -
Porosity Maps - Interactive Exploration and Visual Analysis of Porosity in Carbon Fiber Reinforced Polymers
(The Eurographics Association and Blackwell Publishing Ltd., 2012)In this work a novel method for the characterization of porosity in carbon fiber reinforced polymers (CFRP) is presented. A visualization pipeline for the interactive exploration and visual analysis of CFRP specimens is ... -
Practical Spectral Photography
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce a low-cost and compact spectral imaging camera design based on unmodified consumer cameras and a custom camera objective. The device can be used in a high-resolution configuration that measures the spectrum ...
