Comparing Personal Image Collections with PICTuReVis
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Digital image collections contain a wealth of information, which for instance can be used to trace illegal activities and investigate criminal networks. We present a method that enables analysts to reveal relations among ... -
Graph Layouts by t-SNE
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We propose a new graph layout method based on a modification of the t-distributed Stochastic Neighbor Embedding (t-SNE) dimensionality reduction technique. Although t-SNE is one of the best techniques for visualizing ... -
Visual Exploration of Global Trade Networks with Time-Dependent and Weighted Hierarchical Edge Bundles on GPU
(The Eurographics Association and John Wiley & Sons Ltd., 2017)The UN Comtrade database is the world's largest repository of bilateral trade data. Their complexity poses a challenge to visualization systems, leading to issues such as scalability and visual clutter. Thus, we propose a ... -
Visualizing a Sequence of a Thousand Graphs (or Even More)
(The Eurographics Association and John Wiley & Sons Ltd., 2017)The visualization of dynamic graphs demands visually encoding at least three major data dimensions: vertices, edges, and time steps. Many of the state-of-the-art techniques can show an overview of vertices and edges but ... -
Graffinity: Visualizing Connectivity in Large Graphs
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Multivariate graphs are prolific across many fields, including transportation and neuroscience. A key task in graph analysis is the exploration of connectivity, to, for example, analyze how signals flow through neurons, ... -
Visual Analysis of Confocal Raman Spectroscopy Data using Cascaded Transfer Function Design
(The Eurographics Association and John Wiley & Sons Ltd., 2017)2D Confocal Raman Microscopy (CRM) data consist of high dimensional per-pixel spectral data of 1000 bands and allows for complex spectral and spatial-spectral analysis tasks, i.e., in material discrimination, material ... -
NEREx: Named-Entity Relationship Exploration in Multi-Party Conversations
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Abstract We present NEREx, an interactive visual analytics approach for the exploratory analysis of verbatim conversational transcripts. By revealing different perspectives on multi-party conversations, NEREx gives an entry ... -
Cycle Plot Revisited: Multivariate Outlier Detection Using a Distance-Based Abstraction
(The Eurographics Association and John Wiley & Sons Ltd., 2017)The cycle plot is an established and effective visualization technique for identifying and comprehending patterns in periodic time series, like trends and seasonal cycles. It also allows to visually identify and contextualize ... -
Integrating Visual Analytics Support for Grounded Theory Practice in Qualitative Text Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We present an argument for using visual analytics to aid Grounded Theory methodologies in qualitative data analysis. Grounded theory methods involve the inductive analysis of data to generate novel insights and theoretical ... -
Interactive Ambiguity Resolution of Named Entities in Fictional Literature
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Named entity recognition (NER) denotes the task to detect entities and their corresponding classes, such as person or location, in unstructured text data. For most applications, state of the art NER software is producing ... -
Stardust: Accessible and Transparent GPU Support for Information Visualization Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Web-based visualization libraries are in wide use, but performance bottlenecks occur when rendering, and especially animating, a large number of graphical marks. While GPU-based rendering can drastically improve performance, ... -
Sliceplorer: 1D Slices for Multi-dimensional Continuous Functions
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Multi-dimensional continuous functions are commonly visualized with 2D slices or topological views. Here, we explore 1D slices as an alternative approach to show such functions. Our goal with 1D slices is to combine the ... -
Interactive Regression Lens for Exploring Scatter Plots
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Data analysis often involves finding models that can explain patterns in data, and reduce possibly large data sets to more compact model-based representations. In Statistics, many methods are available to compute model ... -
Visualizing the Uncertainty of Graph-based 2D Segmentation with Min-path Stability
(The Eurographics Association and John Wiley & Sons Ltd., 2017)This paper presents a novel approach to visualize the uncertainty in graph-based segmentations of scalar data. Segmentation of 2D scalar data has wide application in a variety of scientific and medical domains. Typically, ... -
Sclow Plots: Visualizing Empty Space
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Scatter plots are mostly used for correlation analysis, but are also a useful tool for understanding the distribution of highdimensional point cloud data. An important characteristic of such distributions are clusters, and ... -
Overview + Detail Visualization for Ensembles of Diffusion Tensors
(The Eurographics Association and John Wiley & Sons Ltd., 2017)A Diffusion Tensor Imaging (DTI) group study consists of a collection of volumetric diffusion tensor datasets (i.e., an ensemble) acquired from a group of subjects. The multivariate nature of the diffusion tensor imposes ... -
Visual Verification of Cancer Staging for Therapy Decision Support
(The Eurographics Association and John Wiley & Sons Ltd., 2017)It is generally accepted practice that each cancer patient case should be discussed in a clinical expert meeting, the so-called tumor board. A central role in finding the best therapy options for patients with solid tumors ... -
Glyph-Based Comparative Stress Tensor Visualization in Cerebral Aneurysms
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We present the first visualization tool that enables a comparative depiction of structural stress tensor data for vessel walls of cerebral aneurysms. Such aneurysms bear the risk of rupture, whereas their treatment also ... -
Visual Comparison of Eye Movement Patterns
(The Eurographics Association and John Wiley & Sons Ltd., 2017)In eye tracking research, finding eye movement patterns and similar strategies between participants' eye movements is important to understand task solving strategies and obstacles. In this application paper, we present a ... -
Empirically Measuring Soft Knowledge in Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2017)In this paper, we present an empirical study designed to evaluate the hypothesis that humans' soft knowledge can enhance the cost-benefit ratio of a visualization process by reducing the potential distortion. In particular, ...
