Learning a Perceptual Quality Metric for Correlation in Scatterplots
(The Eurographics Association, 2019)
Visual quality metrics describe the quality and efficiency of multidimensional data visualizations in order to guide data analysts during exploration tasks. Current metrics are usually based on empirical algorithms which ...
Visual Analytics of Simulation Ensembles for Network Dynamics
(The Eurographics Association, 2019)
A central question in the field of Network Science is to analyze the role of a given network topology on the dynamical behavior captured by time-varying simulations executed on the network. These dynamical systems are also ...
Cluster-based Analysis of Multi-Parameter Distributions in Cloud Simulation Ensembles
(The Eurographics Association, 2019)
The proposed approach enables a comparative visual exploration of multi-parameter distributions in time-varying 3D ensemble simulations. To investigate whether dominant trends in such distributions occur, we consider the ...
Consistent Filtering of Videos and Dense Light-Fields Without Optic-Flow
(The Eurographics Association, 2019)
A convenient post-production video processing approach is to apply image filters on a per-frame basis. This allows the flexibility of extending image filters-originally designed for still images-to videos. However, per-image ...
A Visual Analytics Tool for Cohorts in Motion Data
(The Eurographics Association, 2019)
Motion data are curves over time in a 1D, 2D, or 3D space. To analyze sets of curves, machine learning methods can be applied to cluster them and detect outliers. However, often metadata or prior knowledge of the analyst ...
Stochastic Convolutional Sparse Coding
(The Eurographics Association, 2019)
State-of-the-art methods for Convolutional Sparse Coding usually employ Fourier-domain solvers in order to speed up the convolution operators. However, this approach is not without shortcomings. For example, Fourier-domain ...
Visualizing Transport and Mixing in Particle-based Fluid Flows
(The Eurographics Association, 2019)
To gain insight into large, time-dependent particle-based fluid flows, we visually analyze Lagrangian coherent structures (LCS), a robust skeleton of the underlying particle dynamics. To identify these coherent structures, ...
Normal Map Bias Reduction for Many-Lights Multi-View Photometric Stereo
(The Eurographics Association, 2019)
In this paper, we improve upon an existing many-lights multi-view photometric stereo approach. Firstly, we show how to detect continuous regions for normal integration, which leads to a fully automatic reconstruction ...
Local Remote Photoplethysmography Signal Analysis for Application in Presentation Attack Detection
(The Eurographics Association, 2019)
This paper presents a method to analyze and visualize the local blood flow through human skin tissue within the face and neck. The method is based on the local signal characteristics and extracts and analyses the local ...
RodMesh: Two-handed 3D Surface Modeling in Virtual Reality
(The Eurographics Association, 2019)
User interfaces for 3D shape modeling in Virtual Reality (VR), unlike basic tasks such as text input and item selection, have been less explored in research so far. Shape modeling in 3D lends itself very well to VR, since ...
