Toward a Lagrangian Vector Field Topology
(The Eurographics Association and Blackwell Publishing Ltd., 2010)In this paper we present an extended critical point concept which allows us to apply vector field topology in the case of unsteady flow.We propose a measure for unsteadiness which describes the rate of change of the ... -
Topology Aware Stream Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2010)We present an algorithm that allows stream surfaces to recognize and adapt to vector field topology. Standard stream surface algorithms either refine the surface uncontrolled near critical points which slows down the ... -
A Maximum Enhancing Higher-Order Tensor Glyph
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Glyphs are a fundamental tool in tensor visualization, since they provide an intuitive geometric representation of the full tensor information. The Higher-Order Maximum Enhancing (HOME) glyph, a generalization of the ... -
An Evaluation of Glyph Perception for Real Symmetric Traceless Tensor Properties
(The Eurographics Association and Blackwell Publishing Ltd., 2010)A perceptual study of four tensor glyphs for symmetric, real, traceless tensors was performed. Each glyph encodes three properties of the system: Orientation, uniaxiality (alignment along the direction of orientation), and ... -
Visual Analysis of Multi-Joint Kinematic Data
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Kinematics is the analysis of motions without regarding forces or inertial effects, with the purpose of understanding joint behaviour. Kinematic data of linked joints, for example the upper extremity, i.e. the shoulder and ... -
ProbExplorer: Uncertainty-guided Exploration and Editing of Probabilistic Medical Image Segmentation
(The Eurographics Association and Blackwell Publishing Ltd., 2010)In this paper, we develop an interactive analysis and visualization tool for probabilistic segmentation results in medical imaging. We provide a systematic approach to analyze, interact and highlight regions of segmentation ... -
Reusable Visualizations and Animations for Surgery Planning
(The Eurographics Association and Blackwell Publishing Ltd., 2010)For surgical planning, the exploration of 3D visualizations and 2D slice views is essential. However, the generation of visualizations which support the specific treatment decisions is very tedious. Therefore, the reuse ... -
Visual Support for Interactive Post-Interventional Assessment of Radiofrequency Ablation Therapy
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Percutaneous radiofrequency (RF) ablation is a minimally invasive, image-guided therapy for the treatment of liver tumors. The assessment of the ablation area (coagulation) is performed to verify the treatment success as ... -
Topographic Map Visualization from Adaptively Compressed Textures
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Raster-based topographic maps are commonly used in geoinformation systems to overlay geographic entities on top of digital terrain models. Using compressed texture formats for encoding topographic maps allows reducing ... -
Streaming-Enabled Parallel Dataflow Architecture for Multicore Systems
(The Eurographics Association and Blackwell Publishing Ltd., 2010)We propose a new framework design for exploiting multi-core architectures in the context of visualization dataflow systems. Recent hardware advancements have greatly increased the levels of parallelism available with all ... -
Scalable Multi-view Registration for Multi-Projector Displays on Vertically Extruded Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Recent work have shown that it is possible to register multiple projectors on non-planar surfaces using a single uncalibrated camera instead of a calibrated stereo pair when dealing with a special class of non-planar ... -
An Interactive Visual Analytics System for Bridge Management
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Bridges deteriorate over their life cycles and require continuous maintenance to ensure their structural integrity, and in turn, the safety of the public. Maintaining bridges is a multi-faceted operation that requires both ... -
Pathline: A Tool For Comparative Functional Genomics
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Biologists pioneering the new field of comparative functional genomics attempt to infer the mechanisms of gene regulation by looking for similarities and differences of gene activity over time across multiple species. They ... -
Video Visualization for Snooker Skill Training
(The Eurographics Association and Blackwell Publishing Ltd., 2010)We present a feasibility study on using video visualization to aid snooker skill training. By involving the coaches and players in the loop of intelligent reasoning, our approach addresses the difficulties of automated ... -
DTI in Context: Illustrating Brain Fiber Tracts In Situ
(The Eurographics Association and Blackwell Publishing Ltd., 2010)We present an interactive illustrative visualization method inspired by traditional pen-and-ink illustration styles. Specifically, we explore how to provide context around DTI fiber tracts in the form of surfaces of the ... -
Illustrative White Matter Fiber Bundles
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Diffusion Tensor Imaging (DTI) has made feasible the visualization of the fibrous structure of the brain white matter. In the last decades, several fiber-tracking methods have been developed to reconstruct the fiber tracts ... -
Effective Techniques to Visualize Filament-Surface Relationships
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Combined visualizations of filamentous structures and surrounding volumetric objects are common in biological and medical applications. Often, the structures spatial relationships remain unclear to the viewer. In this ... -
HyperMoVal: Interactive Visual Validation of Regression Models for Real-Time Simulation
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Abstract During the development of car engines, regression models that are based on machine learning techniques are increasingly important for tasks which require a prediction of results in real-time. While the validation ... -
Topological Landscape Ensembles for Visualization of Scalar-Valued Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Visual representation techniques enable perception and exploration of scientific data. Following the topological landscapes metaphor ofWeber et al., we provide a new algorithm for visualizing scalar functions defined on ... -
Dynamic Multi-View Exploration of Shape Spaces
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Statistical shape modeling is a widely used technique for the representation and analysis of the shapes and shape variations present in a population. A statistical shape model models the distribution in a high dimensional ...
