Feature-Driven Visual Analytics of Chaotic Parameter-Dependent Movement
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Analyzing movements in their spatial and temporal context is a complex task. We are additionally interested in understanding the movements' dependency on parameters that govern the processes behind the movement. We propose ... -
Fiber Surfaces: Generalizing Isosurfaces to Bivariate Data
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Scientific visualization has many effective methods for examining and exploring scalar and vector fields, but rather fewer for bivariate fields. We report the first general purpose approach for the interactive extraction ... -
Finite-Time Mass Separation for Comparative Visualizations of Inertial Particles
(The Eurographics Association and John Wiley & Sons Ltd., 2015)The visual analysis of flows with inertial particle trajectories is a challenging problem because time-dependent particle trajectories additionally depend on mass, which gives rise to an infinite number of possible ... -
Frontmatter: EuroVis 2015 Eurographics Conference on Visualization
(Eurographics Association, 2015) -
GraphUnit: Evaluating Interactive Graph Visualizations Using Crowdsourcing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present GraphUnit, a framework and online service that automates the process of designing, running and analyzing results of controlled user studies of graph visualizations by leveraging crowdsourcing and a set of ... -
Guided Volume Editing based on Histogram Dissimilarity
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Segmentation of volumetric data is an important part of many analysis pipelines, but frequently requires manual inspection and correction. While plenty of volume editing techniques exist, it remains cumbersome and errorprone ... -
Interactive Fusion and Tracking For Multi-Modal Spatial Data Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Scientific data acquired through sensors which monitor natural phenomena, as well as simulation data that imitate time-identified events, have fueled the need for interactive techniques to successfully analyze and understand ... -
Interactive Visual Analysis for Vehicle Detector Data
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Visualization of vehicle detection (VD) data is essential because the data play an important role in traffic control and policy development. Most previous works focus on visualizing trajectories obtained from global ... -
Learning Probabilistic Transfer Functions: A Comparative Study of Classifiers
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Complex volume rendering tasks require high-dimensional transfer functions, which are notoriously difficult to design. One solution to this is to learn transfer functions from scribbles that the user places in the volumetric ... -
Map-based Visualizations Increase Recall Accuracy of Data
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We investigate the memorability of data represented in two different visualization designs. In contrast to recent studies that examine which types of visual information make visualizations memorable, we examine the effect ... -
MoleCollar and Tunnel Heat Map Visualizations for Conveying Spatio-Temporo-Chemical Properties Across and Along Protein Voids
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Studying the characteristics of proteins and their inner void space, including their geometry, physico-chemical properties and dynamics are instrumental for evaluating the reactivity of the protein with other small molecules. ... -
Mosaic Drawings and Cartograms
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Cartograms visualize quantitative data about a set of regions such as countries or states. There are several different types of cartograms and - for some - algorithms to automatically construct them exist. We focus on ... -
A Multi-task Comparative Study on Scatter Plots and Parallel Coordinates Plots
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Previous empirical studies for comparing parallel coordinates plots and scatter plots showed some uncertainty about their relative merits. Some of these studies focused on the task of value retrieval, where visualization ... -
A Novel Framework for Visual Detection and Exploration of Performance Bottlenecks in Organic Photovoltaic Solar Cell Materials
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Current characterization methods of the so-called Bulk Heterojunction (BHJ), which is the main material of Organic Photovoltaic (OPV) solar cells, are limited to the analysis of global fabrication parameters. This reduces ... -
Perfopticon: Visual Query Analysis for Distributed Databases
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Distributed database performance is often unpredictable due to issues such as system complexity, network congestion, or imbalanced data distribution. These issues are difficult for users to assess in part due to the opaque ... -
Persistent Homology for the Evaluation of Dimensionality Reduction Schemes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)High-dimensional data sets are a prevalent occurrence in many application domains. This data is commonly visualized using dimensionality reduction (DR) methods. DR methods provide e.g. a two-dimensional embedding of the ... -
Photoelasticity Raycasting
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel physically-based method to visualize stress tensor fields. By incorporating photoelasticity into traditional raycasting and extending it with reflection and refraction, taking into account polarization, ... -
Quantitative Measures for Cartogram Generation Techniques
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Cartograms are used to visualize geographically distributed data by scaling the regions of a map (e.g., US states) such that their areas are proportional to some data associated with them (e.g., population). Thus the ... -
Rationale Visualization for Safety and Security
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In safety and security domains where objects of interest (OOI), such as people, vessels, or transactions, are continuously monitored, automated reasoning is required due to their sheer number and volume of information. We ... -
Refinery: Visual Exploration of Large, Heterogeneous Networks through Associative Browsing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Browsing is a fundamental aspect of exploratory information-seeking. Associative browsing represents a common and intuitive set of exploratory strategies in which users step iteratively from familiar to novel bits of ...
