Volume Rendering Using Principal Component Analysis
(The Eurographics Association, 2016)We investigate the use of Principal Component Analysis (PCA) for image-based volume rendering. We compute an eigenspace using training images, pre-rendered using a standard raycaster, from a spherically distributed range ... -
Hierarchical Clustering with Multiple-Height Branch-Cut Applied to Short Time-Series Gene Expression Data
(The Eurographics Association, 2016)Rigid adherence to pre-specified thresholds and static graphical representations can lead to incorrect decisions on merging of clusters. As an alternative to existing automated or semi-automated methods, we developed a ... -
Features vs Prototypes: Amplifying Cognition with Common Data Graphics
(The Eurographics Association, 2016)The most common and important data visualizations, such as barcharts or scatterplots are typically feature-based. In this paper we question whether feature-based representations are favorable from the cognition point of ... -
Geometry-Aware Visualization of Performance Data
(The Eurographics Association, 2016)Phenomena in the performance behaviour of high-performance computing (HPC) applications can stem from the HPC system itself, from the application's code, but also from the simulation domain. In order to analyse the latter ... -
InVITe - Towards Intuitive Visualization of Iterations over Text
(The Eurographics Association, 2016)With InVITe, we are working towards intuitive visualization to support review of iterative modifications on text documents. In order to accomplish this, we perform simple matching of text snippets between the two versions ... -
Interactive Exploration of Student Generated Content presented in Blogs
(The Eurographics Association, 2016)Nowadays blogs are regarded as tools for communication as well as an important source for spreading information in almost every subject. In recent years, school teachers have started to take advantage of this technology ... -
Tracking Space-Filling Features by Two-Step Optimization
(The Eurographics Association, 2016)We present a novel approach for tracking space-filling features, i.e., a set of features covering the entire domain. The assignment between successive time steps is determined by a two-step, global optimization scheme. ... -
Visual Analytics for Fraud Detection: Focusing on Profile Analysis
(The Eurographics Association, 2016)Financial institutions are always interested in ensuring security and quality for their customers. Banks, for instance, need to identify and avoid harmful transactions. In order to detect fraudulent operations, data mining ... -
Visualization-Aware Color Design
(The Eurographics Association, 2016)Color encoding design currently focuses on the colors themselves: visualization designers choose sets of colors that work well in isolation. However, the effectiveness of a color encoding depends on properties of the ... -
Query by Visual Words: Visual Search for Scatter Plot Visualizations
(The Eurographics Association, 2016)Finding interesting views in large collections of data visualizations, e.g., scatter plots, is challenging. Recently, ranking views based on heuristic quality measures has been proposed. However, quality measures may fail ... -
Transfer Function Optimization Based on a Combined Model of Visibility and Saliency
(The Eurographics Association, 2016)We present an automated technique to optimize the clarity of features in visualizations of 3D volume datasets. By adjusting the opacity transfer function, we achieve user-specified target distributions of feature conspicuity. ... -
MetricScalpel: Analyzing Diagnostic Outcomes with Exploratory Data Visualization
(The Eurographics Association, 2016)Healthcare data is the emerging force to push ahead smarter clinical solutions. However, unforeseen challenges like unmanaged massive data and costly access to it make it difficult for domain experts to easily derive ... -
When Individual Data Points Matter: Interactively Analysing Classification Landscapes
(The Eurographics Association, 2016)The selection of classification models among several options with similar accuracy cannot be done through purely automated methods, and especially in scenarios in which the cost of misclassified instances is crucial, such ... -
Tracking and Visualizing Dynamic Structures in Multichannel EEG Coherence Networks
(The Eurographics Association, 2016)An electroencephalography (EEG) coherence network represents functional brain connectivity, and is constructed by calculating the coherence between pairs of electrode signals as a function of frequency. Visualization of ... -
Quantitative Evaluation for Edge Bundling Based on Structural Aesthetics
(The Eurographics Association, 2016)This study proposes a method to evaluate the efficiency of edge bundling. Edge bundling is important to improve visual clutter of edge visualization. However, the evaluation of edge bundling is based only on qualitative ... -
User Interaction Visualization for Design Synthesis
(The Eurographics Association, 2016)Through the synthesis of gathered user research data, interaction designers are able to generate design proposals. Logging user interactions with a software provides a rich set of data that can give further insights into ... -
Coloring Interactive Compositional Dot Maps
(The Eurographics Association, 2016)We propose an algorithmic color scheme for zoom-able compositional dot maps. Contrary to existing methods, it uses density, composition, and zoom level to color the pixels of the resulting dot map. We describe the method ... -
Visual Analysis of Text Annotations for Stance Classification with ALVA
(The Eurographics Association, 2016)The automatic detection and classification of stance taking in text data using natural language processing and machine learning methods create an opportunity to gain insight about the writers' feelings and attitudes towards ... -
Visualizing Article Similarities in Wikipedia
(The Eurographics Association, 2016)In this poster we present intermediate results regarding visual text analytics on Wikipedia. We implemented a visualization providing insight about similarities among Wikipedia articles in terms of structure as well as ... -
Understanding Networks beyond Overlapping Clusters
(The Eurographics Association, 2016)Tasks associated with the investigation of large complex clustered networks are widespread in various research areas. Among the popular and common approaches to exploratory analysis, it is definitely worthwhile to underscore ...
