Vortex Analysis in Uncertain Vector Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present an approach to extract and visualize vortex structures in uncertain vector fields. For this, we generalize the concepts of the most common vortex detectors to uncertain vector fields, namely the λ ...
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 ...
Authoring Narrative Visualizations with Ellipsis
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Data visualization is now a popular medium for journalistic storytelling. However, current visualization tools either lack support for storytelling or require significant technical expertise. Informed by interviews with ...
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, ...
Perceptual Global Illumination Cancellation in Complex Projection Environments
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
The unintentional scattering of light between neighboring surfaces in complex projection environments increases the brightness and decreases the contrast, disrupting the appearance of the desired imagery. To achieve ...
Anaglyph Stereo Without Ghosting
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Anaglyph stereo provides a low-budget solution to viewing stereoscopic images. However, it may suffer from ghosting and bad color reproduction. Here we address the first issue. We present a novel technique to perceptually ...
Tablorer - An Interactive Tree Visualization System for Tablet PCs
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
A variety of mobile devices are available today, but there is no dominant tree visualization system in the devices. This paper proposes Tablorer, a novel interactive tree visualization system for medium-sized mobile devices, ...
