Perceptual Evaluation of Ghosted View Techniques for the Exploration of Vascular Structures and Embedded Flow
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents three controlled perceptual studies investigating the visualization of the cerebral aneurysm anatomy with embedded flow visualization. We evaluate and compare the common semitransparent visualization ... -
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 ... -
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 ... -
The Undistort Lens
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Detail-in-context lens techniques can be useful for exploring visualizations of data spaces that are too large or have too much detail to fit in regular displays. For example, by bending the space in the right way we can ... -
Prostate Cancer Visualization from MR Imagery and MR Spectroscopy
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Prostate cancer is one of the most prevalent cancers among males, and the use of magnetic resonance imaging (MRI) has been suggested for its detection. A framework is presented for scoring and visualizing various MR data ... -
Stable Morse Decompositions for Piecewise Constant Vector Fields on Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Numerical simulations and experimental observations are inherently imprecise. Therefore, most vector fields of interest in scientific visualization are known only up to an error. In such cases, some topological features, ... -
Visualising Errors in Animal Pedigree Genotype Data
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Genetic analysis of a breeding animal population involves determining the inheritance pattern of genotypes for multiple genetic markers across the individuals in the population pedigree structure. However, experimental ... -
Flowstrates: An Approach for Visual Exploration of Temporal Origin-Destination Data
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Many origin-destination datasets have become available in the recent years, e.g. flows of people, animals, money, material, or network traffic between pairs of locations, but appropriate techniques for their exploration ... -
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 ... -
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 ... -
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 ... -
An Evaluation of Visualization Techniques to Illustrate Statistical Deformation Models
(The Eurographics Association and Blackwell Publishing Ltd., 2011)As collections of 2D/3D images continue to grow, interest in effective ways to visualize and explore the statistical morphological properties of a group of images has surged. Recently, deformation models have emerged as ... -
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 ... -
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 ... -
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 ... -
Comparison of Multiple Weighted Hierarchies: Visual Analytics for Microbe Community Profiling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We propose visual analytics techniques to support concurrent comparison of hundreds of cumulatively weighted instances of a single hierarchy. This includes a node-link representation of the hierarchy where nodes depict the ... -
Piecewise Laplacian-based Projection for Interactive Data Exploration and Organization
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Multidimensional projection has emerged as an important visualization tool in applications involving the visual analysis of high-dimensional data. However, high precision projection methods are either computationally ... -
A Framework for Exploring Multidimensional Data with 3D Projections
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Visualization of high-dimensional data requires a mapping to a visual space. Whenever the goal is to preserve similarity relations a frequent strategy is to use 2D projections, which afford intuitive interactive exploration, ... -
Visualizing High-Dimensional Structures by Dimension Ordering and Filtering using Subspace Analysis
(The Eurographics Association and Blackwell Publishing Ltd., 2011)High-dimensional data visualization is receiving increasing interest because of the growing abundance of highdimensional datasets. To understand such datasets, visualization of the structures present in the data, such as ... -
Automatic Registration of Multi-Projector Domes Using a Single Uncalibrated Camera
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In this paper we present a novel technique for easily calibrating multiple casually aligned projectors on spherical domes using a single uncalibrated camera. Using the prior knowledge of the display surface being a dome, ...
