TimeRadarTrees: Visualizing Dynamic Compound Digraphs
(The Eurographics Association and Blackwell Publishing Ltd., 2008)The evolution of dependencies in information hierarchies can be modeled by sequences of compound digraphs with edge weights. In this paper we present a novel approach to visualize such sequences of graphs. It uses radial ... -
Topology-Preserving lambda_2-based Vortex Core Line Detection for Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2008)We propose a novel vortex core line extraction method based on the lambda_2 vortex region criterion in order to improve the detection of vortex features for 3D flow visualization. The core line is defined as a curve that ... -
Towards Closing the Analysis Gap: Visual Generation of Decision Supporting Schemes from Raw Data
(The Eurographics Association and Blackwell Publishing Ltd., 2008)The derivation, manipulation and verification of analytical models from raw data is a process which requires a transformation of information across different levels of abstraction. We introduce a concept for the coupling ... -
Virtual Klingler Dissection: Putting Fibers into Context
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Fiber tracking is a standard tool to estimate the course of major white matter tracts from diffusion tensor magnetic resonance imaging (DT-MRI) data. In this work, we aim at supporting the visual analysis of classical ... -
Visual Abstractions of Solvent Pathlines near Protein Cavities
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Water is known to play a crucial role in protein structure, flexibility and activity. The use of molecular dynamics simulations allows detailed studies of complex protein-solvent interactions. Cluster analysis and density-based ... -
Visual Analysis and Semantic Exploration of Urban LIDAR Change Detection
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Many previous approaches to detecting urban change from LIDAR point clouds interpolate the points into rasters, perform pixel-based image processing to detect changes, and produce 2D images as output. We present a method ... -
Visual Clustering in Parallel Coordinates
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Parallel coordinates have been widely applied to visualize high-dimensional and multivariate data, discerning patterns within the data through visual clustering. However, the effectiveness of this technique on large data ... -
Visual Comparison of Hierarchically Organized Data
(The Eurographics Association and Blackwell Publishing Ltd., 2008)We provide a novel visualization method for the comparison of hierarchically organized data. Our technique visualizes a pair of hierarchies that are to be compared and simultaneously depicts how these hierarchies are related ... -
Visual Inspection of Multivariate Graphs
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Most graph visualization techniques focus on the structure of graphs and do not offer support for dealing with node attributes and edge labels. To enable users to detect relations and patterns in terms of data associated ... -
Visualizing Genome Expression and Regulatory Network Dynamics in Genomic and Metabolic Context
(The Eurographics Association and Blackwell Publishing Ltd., 2008)DNA microarrays are used to measure the expression levels of thousands of genes simultaneously. In a time series experiment, the gene expressions are measured as a function of time. We present an application for integrated ...
