3D Soft Segmentation and Visualization of Medical Data Based on Nonlinear Diffusion and Distance Functions
(The Eurographics Association, 2006)Visualization of medical 3D data is a complex problem, since the raw data is often unsuitable for standard techniques like Direct Volume Rendering. Some kind of pre-treatment is necessary, usually segmentation of the ... -
Affiliation Dynamics with an Application to Movie-Actor Biographies
(The Eurographics Association, 2006)We propose a visualization approach for dynamic affiliation networks in which events are characterized by a set of descriptors. It uses a radial ripple metaphor to display the passing of time and conveys relations among ... -
The alpha -histogram: Using Spatial Coherence to Enhance Histograms and Transfer Function Design
(The Eurographics Association, 2006)The high complexity of Transfer Function (TF) design is a major obstacle to widespread routine use of Direct Volume Rendering, particularly in the case of medical imaging. Both manual and automatic TF design schemes would ... -
Application-Oriented Extensions of Profile Flags
(The Eurographics Association, 2006)This paper discusses two applications of probing dense volumetric data for MR orthopedics and dynamic contrast enhanced MRI mammography. In order not to reduce the context information and to extract the essential part of ... -
Automating Transfer Function Design for Volume Rendering Using Hierarchical Clustering of Material Boundaries
(The Eurographics Association, 2006)Transfer function design plays a crucial role in direct volume rendering. Furthermore, it has a major influence on the efficiency of the visualization process. We have developed a framework that facilitates the semi-automatic ... -
A Case Study: Visualizing Material Point Method Data
(The Eurographics Association, 2006)The Material Point Method is used for complex simulation of solid materials represented using many individual particles. Visualizing such data using existing polygonal or volumetric methods does not accurately encapsulate ... -
Combining Extended Table Lens and Treemap Techniques for Visualizing Tabular Data
(The Eurographics Association, 2006)We present a framework for visualizing large tabular data that combines two views: the table view and the treemap view. The table view extends the known table lens as follows: We cluster related elements to reduce subsampling ... -
CVSgrab: Mining the History of Large Software Projects
(The Eurographics Association, 2006)Many software projects use Software Configuration Management systems to support their development process. Such systems accumulate in time large amounts of information useful for process accounting and auditing. We study ... -
D2VR: High-Quality Volume Rendering of Projection-based Volumetric Data
(The Eurographics Association, 2006)Volume rendering techniques are conventionally classified as either direct or indirect methods. Indirect methods require to transform the initial volumetric model into an intermediate geometrical model in order to efficiently ... -
Data Reconstruction and Visualization Techniques for Forensic Pathology
(The Eurographics Association, 2006)Forensic pathology is largely concerned with the determination of the cause and manner of deaths after accidents, or other circumstances in criminal investigations. A major task in that process is the documentation of ... -
Direct Isosurface Extraction from Scattered Volume Data
(The Eurographics Association, 2006)Isosurface extraction is a standard visualization method for scalar volume data and has been subject to research for decades. Nevertheless, to our knowledge, no isosurface extraction method exists that directly extracts ... -
Efficient Surface Reconstruction from Noisy Data using Regularized Membrane Potentials
(The Eurographics Association, 2006)We present a novel, physically-motivated method for surface reconstruction that can recover smooth surfaces from noisy and sparse data sets, without using orientation information. A new volumetric technique based on ... -
Enhanced Visualizations of Thermographic Data in Process Industry
(The Eurographics Association, 2006)In this paper, we describe an improved method for visualization of thermographic data in the paper and pulp process industry. We present an application that allows process operators to freely choose how absolute temperatures ... -
Enhancing Slice-based Visualizations of Medical Volume Data
(The Eurographics Association, 2006)Slice-based visualizations of CT and MRI data are frequently used for diagnosis, intervention planning and intraoperative navigation since they allow a precise analysis and localization. We present new techniques to enhance ... -
Evaluating the Effectiveness of Tree Visualization Systems for Knowledge Discovery
(The Eurographics Association, 2006)User studies, evaluations, and comparisons of tree visualization systems have so far focused on questions that can readily be answered by simple, automated queries without needing visualization. Studies are lacking on the ... -
Fast Ray Traversal of Tetrahedral and Hexahedral Meshes for Direct Volume Rendering
(The Eurographics Association, 2006)The importance of high-performance rendering of unstructured or curvilinear data sets has increased significantly, mainly due to its use in scientific simulations such as computational fluid dynamics and finite element ... -
GPU-Accelerated Volume Splatting With Elliptical RBFs
(The Eurographics Association, 2006)Radial Basis Functions (RBFs) have become a popular rendering primitive, both in surface and in volume rendering. This paper focuses on volume visualization, giving rise to 3D kernels. RBFs are especially convenient for ... -
GPU-Based Hyperstreamlines for Diffusion Tensor Imaging
(The Eurographics Association, 2006)We propose a new approach for the visualization of hyperstreamlines, which offers potential for better scalability than the conventional polygon-based approach. Our method circumvents the bandwidth bottleneck between the ... -
