Visualization of Uncertain Multivariate Data via Feature Confidence Level-Sets
(The Eurographics Association, 2021)
Recent advancements in multivariate data visualization have opened new research opportunities for the visualization community. In this paper, we propose an uncertain multivariate data visualization technique called feature ...
VATUN: Visual Analytics for Testing and Understanding Convolutional Neural Networks
(The Eurographics Association, 2021)
Convolutional neural networks (CNNs) are popularly used in a wide range of applications, such as computer vision, natural language processing, and human-computer interaction. However, testing and understanding a trained ...
Evaluating Interactive Comparison Techniques in a Multiclass Density Map for Visual Crime Analytics
(The Eurographics Association, 2021)
Techniques for presenting objects spatially via density maps have been thoroughly studied, but there is lack of research on how to display this information in the presence of several classes, i.e., multiclass density maps. ...
A Multilevel Approach for Event-Based Dynamic Graph Drawing
(The Eurographics Association, 2021)
The timeslice is the predominant method for drawing and visualizing dynamic graphs. However, when nodes and edges have real coordinates along the time axis, it becomes difficult to organize them into discrete timeslices, ...
A Winding Angle Framework for Tracking and Exploring Eddy Transport in Oceanic Ensemble Simulations
(The Eurographics Association, 2021)
Oceanic eddies, which are highly mass-coherent vortices traveling through the earth's waters, are of special interest for their mixing properties. Therefore, large-scale ensemble simulations are performed to approximate ...
DanceMoves: A Visual Analytics Tool for Dance Movement Analysis
(The Eurographics Association, 2021)
Analyzing body movement as a means of expression is of interest in diverse areas, such as dance, sports, films, as well as anthropology or archaeology. In particular, in choreography, body movements are at the core of ...
TaskVis: Task-oriented Visualization Recommendation
(The Eurographics Association, 2021)
General visualization recommendation systems typically make design decisions of the dataset automatically. However, these systems are only able to prune meaningless visualizations but fail to recommend targeted results. ...
Toward an Interactive Voronoi Treemap for Manual Arrangement and Grouping
(The Eurographics Association, 2021)
Interactive spatial arrangement and grouping (A&G) of images is a critical step of the sense-making process. We argue that to support A&G tasks, a visual encoding idiom should avoid clutter, show groups explicitly, and ...
Algorithmic Improvements on Hilbert and Moore Treemaps for Visualization of Large Tree-structured Datasets
(The Eurographics Association, 2021)
Hilbert and Moore treemaps are based on the same named space-filling curves to lay out tree-structured data for visualization. One main component of them is a partitioning subroutine, whose algorithmic complexity poses ...
Revealing Multimodality in Ensemble Weather Prediction
(The Eurographics Association, 2021)
Ensemble methods are widely used to simulate complex non-linear systems and to estimate forecast uncertainty. However, visualizing and analyzing ensemble data is challenging, in particular when multimodality arises, i.e., ...
