Networks of Names: Visual Exploration and Semi-Automatic Tagging of Social Networks from Newspaper Articles
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Understanding relationships between people and organizations by reading newspaper articles is difficult to manage for humans due to the large amount of data. To address this problem, we present and evaluate a new visual ... -
Comparative Exploration of Document Collections: a Visual Analytics Approach
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present an analysis and visualization method for computing what distinguishes a given document collection from others. We determine topics that discriminate a subset of collections from the remaining ones by applying ... -
Comparative Visualization of Molecular Surfaces Using Deformable Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The comparison of molecular surface attributes is of interest for computer aided drug design and the analysis of biochemical simulations. Due to the non-rigid nature of molecular surfaces, partial shape matching is feasible ... -
Line Integral Convolution for Real-Time Illustration of Molecular Surface Shape and Salient Regions
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel line drawing algorithm that illustrates surfaces in real-time to convey their shape. We use line integral convolution (LIC) and employ ambient occlusion for illustrative surface rendering. Furthermore, ... -
Visualizing Validation of Protein Surface Classifiers
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Many bioinformatics applications construct classifiers that are validated in experiments that compare their results to known ground truth over a corpus. In this paper, we introduce an approach for exploring the results of ... -
Visualization of Medicine Prescription Behavior
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Medicine prescriptions play an important role in medical treatments. More insight in medicine prescription behavior can lead to more efficient and effective treatments, as well as reflection on prescription behavior for ... -
GuideME: Slice-guided Semiautomatic Multivariate Exploration of Volumes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Multivariate volume visualization is important for many applications including petroleum exploration and medicine. State-of-the-art tools allow users to interactively explore volumes with multiple linked parameter-space ... -
Comparative Blood Flow Visualization for Cerebral Aneurysm Treatment Assessment
(The Eurographics Association and John Wiley and Sons Ltd., 2014)A pathological vessel dilation in the brain, termed cerebral aneurysm, bears a high risk of rupture, and is associated with a high mortality. In recent years, incidental findings of unruptured aneurysms have become more ... -
Illustrative Visualization of Molecular Reactions using Omniscient Intelligence and Passive Agents
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper we propose a new type of a particle systems, tailored for illustrative visualization purposes, in particular for visualizing molecular reactions in biological networks. Previous visualizations of biochemical ... -
4D MRI Flow Coupled to Physics-Based Fluid Simulation for Blood-Flow Visualization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Modern MRI measurements deliver volumetric and time-varying blood-flow data of unprecedented quality. Visual analysis of these data potentially leads to a better diagnosis and risk assessment of various cardiovascular ... -
Volumetric Data Reduction in a Compressed Sensing Framework
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we investigate compressed sensing principles to devise an in-situ data reduction framework for visualization of volumetric datasets. We exploit the universality of the compressed sensing framework and show ... -
Distortion-Guided Structure-Driven Interactive Exploration of High-Dimensional Data
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Dimension reduction techniques are essential for feature selection and feature extraction of complex highdimensional data. These techniques, which construct low-dimensional representations of data, are typically geometrically ... -
InSpectr: Multi-Modal Exploration, Visualization, and Analysis of Spectral Data
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper addresses the increasing demand in industry for methods to analyze and visualize multimodal data involving a spectral modality. Two data modalities are used: high-resolution X-ray computed tomography (XCT) for ... -
Towards an Unbiased Comparison of CC, BCC, and FCC Lattices in Terms of Prealiasing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In the literature on optimal regular volume sampling, the Body-Centered Cubic (BCC) lattice has been proven to be optimal for sampling spherically band-limited signals above the Nyquist limit. On the other hand, if the ... -
RBF Volume Ray Casting on Multicore and Manycore CPUs
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Modern supercomputers enable increasingly large N-body simulations using unstructured point data. The structures implied by these points can be reconstructed implicitly. Direct volume rendering of radial basis function ... -
Parallel Irradiance Caching for Interactive Monte-Carlo Direct Volume Rendering
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose a technique to build the irradiance cache for isotropic scattering simultaneously with Monte Carlo progressive direct volume rendering on a single GPU, which allows us to achieve up to four times increased ... -
Stability of Dissipation Elements: A Case Study in Combustion
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Recently, dissipation elements have been gaining popularity as a mechanism for measurement of fundamental properties of turbulent flow, such as turbulence length scales and zonal partitioning. Dissipation elements segment ... -
Extended Branch Decomposition Graphs: Structural Comparison of Scalar Data
