Robust Reference Frame Extraction from Unsteady 2D Vector Fields with Convolutional Neural Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Robust feature extraction is an integral part of scientific visualization. In unsteady vector field analysis, researchers recently directed their attention towards the computation of near-steady reference frames for vortex ... -
A Visual Tool for the Analysis of Algorithms for Tomographic Fiber Reconstruction in Materials Science
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present visual analysis methods for the evaluation of tomographic fiber reconstruction algorithms by means of analysis, visual debugging and comparison of reconstructed fibers in materials science. The methods are ... -
The Dependent Vectors Operator
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In this paper, we generalize the parallel vectors operator due to Peikert and Roth to arbitrary dimension, i.e., to four-dimensional fields and beyond. Whereas the original operator tested for parallelism of two (derived) ... -
Visualizing for the Non-Visual: Enabling the Visually Impaired to Use Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2019)The majority of visualizations on the web are still stored as raster images, making them inaccessible to visually impaired users. We propose a deep-neural-network-based approach that automatically recognizes key elements ... -
SurgeryCuts: Embedding Additional Information in Maps without Occluding Features
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Visualizing contextual information to a map often comes at the expense of overplotting issues. Especially for use cases with relevant map features in the immediate vicinity of an information to add, occlusion of the relevant ... -
Oui! Outlier Interpretation on Multi-dimensional Data via Visual Analytics
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Outliers, the data instances that do not conform with normal patterns in a dataset, are widely studied in various domains, such as cybersecurity, social analysis, and public health. By detecting and analyzing outliers, ... -
ClustMe: A Visual Quality Measure for Ranking Monochrome Scatterplots based on Cluster Patterns
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose ClustMe, a new visual quality measure to rank monochrome scatterplots based on cluster patterns. ClustMe is based on data collected from a human-subjects study, in which 34 participants judged synthetically ... -
Toward Understanding Representation Methods in Visualization Recommendations through Scatterplot Construction Tasks
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Most visualization recommendation systems predominantly rely on graphical previews to describe alternative visual encodings. However, since InfoVis novices are not familiar with visual representations (e.g., interpretation ... -
An Exploratory User Study of Visual Causality Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Interactive visualization tools are being used by an increasing number of members of the general public; however, little is known about how, and how well, people use visualizations to infer causality. Adapted from the ... -
A User-based Visual Analytics Workflow for Exploratory Model Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Many visual analytics systems allow users to interact with machine learning models towards the goals of data exploration and insight generation on a given dataset. However, in some situations, insights may be less important ... -
Investigating Effects of Visual Anchors on Decision-Making about Misinformation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Cognitive biases are systematic errors in judgment due to an over-reliance on rule-of-thumb heuristics. Recent research suggests that cognitive biases, like numerical anchoring, transfers to visual analytics in the form ... -
Characterizing Exploratory Visual Analysis: A Literature Review and Evaluation of Analytic Provenance in Tableau
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Supporting exploratory visual analysis (EVA) is a central goal of visualization research, and yet our understanding of the process is arguably vague and piecemeal. We contribute a consistent definition of EVA through review ... -
An Ontological Framework for Supporting the Design and Evaluation of Visual Analytics Systems
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Designing, evaluating, and improving visual analytics (VA) systems is a primary area of activities in our discipline. In this paper, we present an ontological framework for recording and categorizing technical shortcomings ... -
VIAN: A Visual Annotation Tool for Film Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2019)While color plays a fundamental role in film design and production, existing solutions for film analysis in the digital humanities address perceptual and spatial color information only tangentially. We introduce VIAN, a ... -
CV3: Visual Exploration, Assessment, and Comparison of CVs
(The Eurographics Association and John Wiley & Sons Ltd., 2019)The Curriculum Vitae (CV, also referred to as ''résumé'') is an established representation of a person's academic and professional history. A typical CV is comprised of multiple sections associated with spatio-temporal, ... -
DIVA: Exploration and Validation of Hypothesized Drug-Drug Interactions
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Adverse reactions caused by drug-drug interactions are a major public health concern. Currently, adverse reaction signals are detected through a tedious manual process in which drug safety analysts review a large number ... -
Multiple Views: Different Meanings and Collocated Words
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We report on an in-depth corpus linguistic study on 'multiple views' terminology and word collocation. We take a broad interpretation of these terms, and explore the meaning and diversity of their use in visualisation ... -
Latent Space Cartography: Visual Analysis of Vector Space Embeddings
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Latent spaces-reduced-dimensionality vector space embeddings of data, fit via machine learning-have been shown to capture interesting semantic properties and support data analysis and synthesis within a domain. Interpretation ... -
A Framework for GPU-accelerated Exploration of Massive Time-varying Rectilinear Scalar Volumes
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We introduce a novel flexible approach to spatiotemporal exploration of rectilinear scalar volumes. Our out-of-core representation, based on per-frame levels of hierarchically tiled non-redundant 3D grids, efficiently ... -
Follow The Clicks: Learning and Anticipating Mouse Interactions During Exploratory Data Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2019)The goal of visual analytics is to create a symbiosis between human and computer by leveraging their unique strengths. While this model has demonstrated immense success, we are yet to realize the full potential of such a ...
