Energy-scale Aware Feature Extraction for Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In the visualization of flow simulation data, feature detectors often tend to result in overly rich response, making some sort of filtering or simplification necessary to convey meaningful images. In this paper we present ... -
Visual Reconstructability as a Quality Metric for Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a novel approach for the evaluation of 2D flow visualizations based on the visual reconstructability of the input vector fields. According to this metric, a visualization has high quality if the underlying data ... -
Lagrangian Coherent Structures with Guaranteed Material Separation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Given an unsteady flow field, one common way to compute Lagrangian Coherent Structures (LCS) is to extract extremal structures of the Finite Time Lyapunov Exponent (FTLE). Experience has shown that the resulting structures ... -
Semantic-Preserving Word Clouds by Seam Carving
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Word clouds are proliferating on the Internet and have received much attention in visual analytics. Although word clouds can help users understand the major content of a document collection quickly, their ability to visually ... -
Exploring Collections of Tagged Text for Literary Scholarship
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Modern literary scholars must combine access to vast collections of text with the traditional close analysis of their field. In this paper, we discuss the design and development of tools to support this work. Based on ... -
Efficient Parallel Vectors Feature Extraction from Higher-Order Data
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The parallel vectors (PV) operator is a feature extraction approach for defining line-type features such as creases (ridges and valleys) in scalar fields, as well as separation, attachment, and vortex core lines in vector ... -
PaperVis: Literature Review Made Easy
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Reviewing literatures for a certain research field is always important for academics. One could use Google-like information seeking tools, but oftentimes he/she would end up obtaining too many possibly related papers, as ... -
A Visual Analytics Approach for Peak-Preserving Prediction of Large Seasonal Time Series
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Time series prediction methods are used on a daily basis by analysts for making important decisions. Most of these methods use some variant of moving averages to reduce the number of data points before prediction. However, ... -
Interactive Visual Analysis of Temporal Cluster Structures
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Cluster analysis is a useful method which reveals underlying structures and relations of items after grouping them into clusters. In the case of temporal data, clusters are defined over time intervals where they usually ... -
Visual Exploration of Time-Series Data with Shape Space Projections
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Time-series data is a common target for visual analytics, as they appear in a wide range of application domains. Typical tasks in analyzing time-series data include identifying cyclic behavior, outliers, trends, and periods ... -
Illustrative Molecular Visualization with Continuous Abstraction
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Molecular systems may be visualized with various degrees of structural abstraction, support of spatial perception, and 'illustrativeness.' In this work we propose and realize methods to create seamless transformations that ... -
Interactive Exploration of Protein Cavities
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a novel application for the interactive exploration of cavities within proteins in dynamic data sets. Inside a protein, cavities can often be found close to the active center. Therefore, when analyzing a molecular ... -
Topology-based Visualization of Transformation Pathways in Complex Chemical Systems
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Studying transformation in a chemical system by considering its energy as a function of coordinates of the system's components provides insight and changes our understanding of this process. Currently, a lack of effective ... -
Progressive Splatting of Continuous Scatterplots and Parallel Coordinates
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Continuous scatterplots and parallel coordinates are used to visualize multivariate data defined on a continuous domain. With the existing techniques, rendering such plots becomes prohibitively slow, especially for large ... -
Visual Coherence for Large-Scale Line-Plot Visualizations
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Displaying a large number of lines within a limited amount of screen space is a task that is common to many different classes of visualization techniques such as time-series visualizations, parallel coordinates, link-node ... -
Curve Density Estimates
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In this work, we present a technique based on kernel density estimation for rendering smooth curves. With this approach, we produce uncluttered and expressive pictures, revealing frequency information about one, or, multiple ...
