Graph Bundling by Kernel Density Estimation
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a fast and simple method to compute bundled layouts of general graphs. For this, we first transform a given graph drawing into a density map using kernel density estimation. Next, we apply an image sharpening ... -
I-SI: Scalable Architecture of Analyzing Latent Topical-Level Information From Social Media Data
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a general visual analytics architecture that is designed and implemented to effectively analyze unstructured social media data on a large scale. Pipelined on a high-performance cluster configuration, MPI processing, ... -
Illustrative Membrane Clipping
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Clipping is a fast, common technique for resolving occlusions. It only requires simple interaction, is easily understandable, and thus has been very popular for volume exploration. However, a drawback of clipping is that ... -
Importance Driven Automatic Color Design for Direct Volume Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2012)This paper introduces an automatic color design method that is driven by an importance function of the objects within a volumetric dataset. Our method allows the user to intuitively modify the object classification and the ... -
Interactive Rendering of Materials and Biological Structures on Atomic and Nanoscopic Scale
(The Eurographics Association and Blackwell Publishing Ltd., 2012)The properties of both inorganic and organic materials and the function of biological structures can often only be understood by analyzing them simultaneously on atomic and nanoscopic, if not mesoscopic, scale. Here, the ... -
Interactive Visualization of Generalized Virtual 3D City Models using Level-of-Abstraction Transitions
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Virtual 3D city models play an important role in the communication of complex geospatial information in a growing number of applications, such as urban planning, navigation, tourist information, and disaster management. ... -
Interface Exchange as an Indicator for Eddy Heat Transport
(The Eurographics Association and Blackwell Publishing Ltd., 2012)The ocean contains many large-scale, long-lived vortices, called mesoscale eddies, that are believed to have a role in the transport and redistribution of salt, heat, and nutrients throughout the ocean. Determining this ... -
iVisClustering: An Interactive Visual Document Clustering via Topic Modeling
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Clustering plays an important role in many large-scale data analyses providing users with an overall understand- ing of their data. Nonetheless, clustering is not an easy task due to noisy features and outliers existing ... -
Kelp Diagrams: Point Set Membership Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present Kelp Diagrams, a novel method to depict set relations over points, i.e., elements with predefined positions. Our method creates schematic drawings and has been designed to take aesthetic quality, efficiency, and ... -
Magnetic Flux Topology of 2D Point Dipoles
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Magnetic fields exhibit higher-order, nonlinear singularities in the form of point-dipole singularities. In addition, due to absence of divergence, they feature only a subset of invariant structures from traditional vector ... -
MarketAnalyzer: An Interactive Visual Analytics System for Analyzing Competitive Advantage Using Point of Sale Data
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Competitive intelligence is a systematic approach for gathering, analyzing, and managing information to make informed business decisions. Many companies use competitive intelligence to identify risks and opportunities ... -
MatchPad: Interactive Glyph-Based Visualization for Real-Time Sports Performance Analysis
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Today real-time sports performance analysis is a crucial aspect of matches in many major sports. For example, in soccer and rugby, team analysts may annotate videos during the matches by tagging specific actions and events, ... -
Multi-layer Illustrative Dense Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a dense visualization of vector fields on multi-layered surfaces. The method is based on the illustration buffer, which provides a screen space representation of the surface, where each pixel stores a list of ... -
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 ... -
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 ... -
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 ... -
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 ... -

Probabilistic Local Features in Uncertain Vector Fields with Spatial Correlation
(The Eurographics Association and Blackwell Publishing Ltd., 2012)In this paper methods for extraction of local features in crisp vector fields are extended to uncertain fields. While in a crisp field local features are either present or absent at some location, in an uncertain field ...
