Rendering and Extracting Extremal Features in 3D Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Visualizing and extracting three-dimensional features is important for many computational science applications, each with their own feature definitions and data types. While some are simple to state and implement (e.g. ... -
Representative Consensus from Limited-Size Ensembles
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Characterizing the uncertainty and extracting reliable visual information from ensemble data have been persistent challenges in various disciplines, specifically in simulation sciences. Many ensemble analysis and visualization ... -
SetCoLa: High-Level Constraints for Graph Layout
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Constraints enable flexible graph layout by combining the ease of automatic layout with customizations for a particular domain. However, constraint-based layout often requires many individual constraints defined over ... -
Spatio-Temporal Contours from Deep Volume Raycasting
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We visualize contours for spatio-temporal processes to indicate where and when non-continuous changes occur or spatial bounds are encountered. All time steps are comprised densely in one visualization, with contours allowing ... -
ThreadReconstructor: Modeling Reply-Chains to Untangle Conversational Text through Visual Analytics
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present ThreadReconstructor, a visual analytics approach for detecting and analyzing the implicit conversational structure of discussions, e.g., in political debates and forums. Our work is motivated by the need to ... -
Time Lattice: A Data Structure for the Interactive Visual Analysis of Large Time Series
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Advances in technology coupled with the availability of low-cost sensors have resulted in the continuous generation of large time series from several sources. In order to visually explore and compare these time series at ... -
Towards Easy Comparison of Local Businesses Using Online Reviews
(The Eurographics Association and John Wiley & Sons Ltd., 2018)With the rapid development of e-commerce, there is an increasing number of online review websites, such as Yelp, to help customers make better purchase decisions. Viewing online reviews, including the rating score and text ... -
Towards User-Centered Active Learning Algorithms
(The Eurographics Association and John Wiley & Sons Ltd., 2018)The labeling of data sets is a time-consuming task, which is, however, an important prerequisite for machine learning and visual analytics. Visual-interactive labeling (VIAL) provides users an active role in the process ... -
Track Xplorer: A System for Visual Analysis of Sensor-based Motor Activity Predictions
(The Eurographics Association and John Wiley & Sons Ltd., 2018)With the rapid commoditization of wearable sensors, detecting human movements from sensor datasets has become increasingly common over a wide range of applications. To detect activities, data scientists iteratively experiment ... -
VirtualDesk: A Comfortable and Efficient Immersive Information Visualization Approach
(The Eurographics Association and John Wiley & Sons Ltd., 2018)3D representations are potentially useful under many circumstances, but suffer from long known perception and interaction challenges. Current immersive technologies, which combine stereoscopic displays and natural interaction, ... -
Visual Analysis of Protein-ligand Interactions
(The Eurographics Association and John Wiley & Sons Ltd., 2018)The analysis of protein-ligand interactions is complex because of the many factors at play. Most current methods for visual analysis provide this information in the form of simple 2D plots, which, besides being quite space ... -
Visual and Quantitative Analysis of Great Arteries' Blood Flow Jets in Cardiac 4D PC-MRI Data
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Flow in the great arteries (aorta, pulmonary artery) is normally laminar with a parabolic velocity profile. Eccentric flow jets are linked to various diseases like aneurysms. Cardiac 4D PC-MRI data provide spatio-temporally ... -
Visualization of 4D Vector Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we present an approach to the topological analysis of four-dimensional vector fields. In analogy to traditional 2D and 3D vector field topology, we provide a classification and visual representation of ... -
Visualizing Expanded Query Results
(The Eurographics Association and John Wiley & Sons Ltd., 2018)When performing queries in web search engines, users often face difficulties choosing appropriate query terms. Search engines therefore usually suggest a list of expanded versions of the user query to disambiguate it or ... -
Visualizing Multidimensional Data with Order Statistics
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Multidimensional data sets are common in many domains, and dimensionality reduction methods that determine a lower dimensional embedding are widely used for visualizing such data sets. This paper presents a novel method ... -
Visualizing the Phase Space of Heterogeneous Inertial Particles in 2D Flows
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In many scientific disciplines, the motion of finite-sized objects in fluid flows plays an important role, such as in brownout engineering, sediment transport, oceanology or meteorology. These finite-sized objects are ...
