Edge-Aware Volume Smoothing Using L0 Gradient Minimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In volume visualization, noise in regions of homogeneous material and at boundaries between different materials poses a great challenge in extracting, analyzing and rendering features of interest. In this paper, we present ... -
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 ... -
Efficient and Adaptive Rendering of 2-D Continuous Scatterplots
(The Eurographics Association and Blackwell Publishing Ltd., 2009)We extend the rendering technique for continuous scatterplots to allow for a broad class of interpolation methods within the spatial grid instead of only linear interpolation. To do this, we propose an approach that projects ... -
Efficient Contrast Effect Compensation with Personalized Perception Models
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Color is one of the most effective visual variables and is frequently used to encode metric quantities. Contrast effects are considered harmful in data visualizations since they significantly bias our perception of colors. ... -
Efficient Display of Background Objects for Virtual Endoscopy using Flexible First-Hit Ray Casting
(The Eurographics Association, 2004)Many applications of virtual endoscopy require the display of background objects behind the semi-transparent surface of the investigated organ. This paper deals with pre-processing and visualization of background objects ... -
Efficient Isosurface Tracking Using Precomputed Correspondence Table
(The Eurographics Association, 2004)Feature tracking is a useful method for visualizing and analyzing time-varying scalar fields. It allows scientists to focus on regions of interest and track their evolution and interaction over time. To allow the user to ... -

(The Eurographics Association, 2004)Feature tracking is a useful method for visualizing and analyzing time-varying scalar fields. It allows scientists to focus on regions of interest and track their evolution and interaction over time. To allow the user to ... -
Efficient Local Histogram Searching via Bitmap Indexing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Representing features by local histograms is a proven technique in several volume analysis and visualization applications including feature tracking and transfer function design. The efficiency of these applications, ... -
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 ... -
Efficient Ray Intersection for Visualization and Navigation of Global Terrain using Spheroidal Height-Augmented Quadtrees
(Springer and The Eurographics Association, 1999)We present an algorithm for efficiently computing ray intersections with multi-resolution global terrain partitioned by spheroidal height-augmented quadtrees. While previous methods support terrain defined on a Cartesian ... -
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 ... -
Efficient Visualization of Large Medical Image Datasets on Standard PC Hardware
(The Eurographics Association, 2003)Fast and accurate algorithms for medical image processing and visualization are becoming increasingly important due to routine acquisition and processing of rapidly growing amounts of data in clinical practice. At the same ... -
Efficiently Rendering Large Volume Data Using Texture Mapping Hardware
(Springer and The Eurographics Association, 1999)Volume rendering with texture mapping hardware is a fast volume rendering method available on high-end workstations. However, limited texture memory often prevents the method from being used to render large volume data ... -
Employing 2D Projections for Fast Visual Exploration of Large Fiber Tracking Data
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Fiber tracts detection is an increasingly common technology for diagnosis and also understanding of brain function. Although tools for tracing and presenting brain fibers are advanced, it is still difficult for physicians ... -
Enclosing Surfaces for Point Clusters Using 3D Discrete Voronoi Diagrams
(The Eurographics Association and Blackwell Publishing Ltd., 2009)Point clusters occur in both spatial and non-spatial data. In the former context they may represent segmented particle data, in the latter context they may represent clusters in scatterplots. In order to visualize such ... -
Energy-scale Aware Feature Extraction for Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In the visualization of flow simulation data, feature detectors often tend to result in overly rich response, making some sort of filtering or simplification necessary to convey meaningful images. In this paper we present ... -
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 Scatterplots with Multi-Dimensional Focal Blur
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Scatterplots directly depict two dimensions of multi-dimensional data points, discarding all other information. To visualize all data, these plots are extended to scatterplot matrices, which distribute the information of ... -
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 ... -
Enhancing the Visualization of Characteristic Structures in Dynamical Systems
(The Eurographics Association, 1998)We present a thread of streamlets as a new technique to visualize dynamical systems in three-dimensional space. A trade-off is made between solely visualizing a mathematical abstraction through lowerdimensional manifolds, ...
