Bilateral Depth Filtering for Enhanced Vessel Reformation
(The Eurographics Association, 2014)
Curved Planar Reformation is a powerful visualization technique for the diagnosis of vascular diseases. It allowsan accurate centerline-driven investigation of vessel lumen while providing valuable anatomical context.Extended ...
The Effect of Information Visualization Delivery on Narrative Construction and Development
(The Eurographics Association, 2014)
We conducted a between-subject experiment with 32 participants to explore how two different models of informationvisualization delivery influence narratives constructed by audiences. The first model involves direct narrativeby ...
Visualizing Graphs as Maps with Contiguous Regions
(The Eurographics Association, 2014)
Relational datasets, which include clustering information, can be visualized with tools such as BubbleSets, Line-Sets, SOM, and GMap. The countries in SOM-based and GMap-based visualizations are fragmented, i.e., theyare ...
Vortex Detection in 4D MRI Data: Using the Proper Orthogonal Decomposition for Improved Noise-Robustness
(The Eurographics Association, 2014)
Recent advances in magnetic resonance imaging (MRI) technology enabled the acquisition of time-resolved 3Dblood flow data. Several flow visualization methods have been applied to these data in order to investigate linksbetween ...
Visualizing Uncertainty in HARDI Tractography Using Superquadric Streamtubes
(The Eurographics Association, 2014)
Standard streamtubes for the visualization of diffusion MRI data are rendered either with a circular or with anelliptic cross section whose aspect ratio indicates the relative magnitudes of the medium and minor ...
Color and Uncertainty: It is not always Black and White
(The Eurographics Association, 2014)
To fully comprehend the meaning and impact of visualized data it is crucial that users are able to perceive andcomprehend the inherent uncertainty of the data in a correct and intuitive way. Data uncertainty is ...
Redesigning the Sequence Logo with Glyph-based Approaches to Aid Interpretation
(The Eurographics Association, 2014)
Sequence logos have been a prominent visualization tool in biological research since their inception two decadesago. Their primary use is in communicating conservation of biological sequences (protein, DNA or RNA), toindicate ...
Studying Color Blending Perception for Data Visualization
(The Eurographics Association, 2014)
Visualization is a powerful way to convey data, showing a great potential for joining and interrelating differentdata items. Nevertheless, when dealing with large amounts of data, visually merging different classes of ...
Per-Fragment Image-based Flow Visualization using Interactive Surface Extraction from Unstructured Grids
(The Eurographics Association, 2014)
We present a method for image-based visualization of flow fields on unstructured grids. For interactive explorationof flow data from CFD simulations, we combine GPU-accelerated surface extraction methods and line ...
Visibility-Driven Depth Determination of Surface Patches in Direct Volume Rendering
(The Eurographics Association, 2014)
This paper presents an algorithm called surfseek for selecting surfaces on the most visible features in directvolume rendering (DVR). The algorithm is based on a previously published technique (WYSIWYP) for picking 3Dlocations ...
