Evolutionary Visual Exploration: Evaluation With Expert Users
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present an Evolutionary Visual Exploration (EVE) system that combines visual analytics with stochastic optimisation to aid the exploration of multidimensional datasets characterised by a large number of possible views ... -
Progressive High-Quality Response Surfaces for Visually Guided Sensitivity Analysis
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In this paper we present a technique which allows us to perform high quality and progressive response surface prediction from multidimensional input samples in an efficient manner. We utilize kriging interpolation to ... -
Evaluating Isosurfaces with Level-set-based Information Maps
(The Eurographics Association and Blackwell Publishing Ltd., 2013)While isosurfaces have been widely used for scalar data visualization, it is often difficult to determine if the selected isosurfaces for visualization are sufficient to represent the entire scalar field. In this paper, ... -
Constructing Isosurfaces with Sharp Edges and Corners using Cube Merging
(The Eurographics Association and Blackwell Publishing Ltd., 2013)A number of papers present algorithms to construct isosurfaces with sharp edges and corners from hermite data, i.e. the exact surface normals at the exact intersection of the surface and grid edges. We discuss some fundamental ... -

Tracing Tuples Across Dimensions: A Comparison of Scatterplots and Parallel Coordinate Plots
(The Eurographics Association and Blackwell Publishing Ltd., 2012)One of the fundamental tasks for analytic activity is retrieving (i.e., reading) the value of a particular quantity in an information visualization. However, few previous studies have compared user performance in such value ... -
Procedural Texture Synthesis for Zoom-Independent Visualization of Multivariate Data
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Simultaneous visualization of multiple continuous data attributes in a single visualization is a task that is important for many application areas. Unsurprisingly, many methods have been proposed to solve this task. However, ... -
Semi-Supervised Dimensionality Reduction based on Partial Least Squares for Visual Analysis of High Dimensional Data
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Dimensionality reduction is employed for visual data analysis as a way to obtaining reduced spaces for high dimensional data or to mapping data directly into 2D or 3D spaces. Although techniques have evolved to improve ... -
A Taxonomy of Visual Cluster Separation Factors
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We provide two contributions, a taxonomy of visual cluster separation factors in scatterplots, and an in-depth qualitative evaluation of two recently proposed and validated separation measures. We initially intended to use ... -
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 ... -
COVRA: A Compression-domain Output-sensitive Volume Rendering Architecture Based on a Sparse Representation of Voxel Blocks
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a novel multiresolution compression-domain GPU volume rendering architecture designed for inter- active local and networked exploration of rectilinear scalar volumes on commodity platforms. In our approach, the ... -
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 ... -
Automating Transfer Function Design with Valley Cell-Based Clustering of 2D Density Plots
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Two-dimensional transfer functions are an effective and well-accepted tool in volume classification. The design of them mostly depends on the user's experience and thus remains a challenge. Therefore, we present an approach ... -
ConnectedCharts: Explicit Visualization of Relationships between Data Graphics
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Multidimensional multivariate data can be visualized using many different well-known charts, such as bar charts, stacked bar charts, grouped bar charts, scatterplots, or pivot tables, or also using more advanced highdimensional ... -
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, ... -
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 ... -
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, ... -
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 ... -
