Interactive Curation of Datasets for Training and Refining Generative Models
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a novel interactive learning-based method for curating datasets using user-defined criteria for training and refining Generative Adversarial Networks. We employ a novel batch-mode active learning strategy to ...
Adaptive Temporal Sampling for Volumetric Path Tracing of Medical Data
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Monte-Carlo path tracing techniques can generate stunning visualizations of medical volumetric data. In a clinical context, such renderings turned out to be valuable for communication, education, and diagnosis. Because a ...
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 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 ...
ShutterApp: Spatio-temporal Exposure Control for Videos
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
A camera's shutter controls the incoming light that is reaching the camera sensor. Different shutters lead to wildly different results, and are often used as a tool in movies for artistic purpose, e.g., they can indirectly ...
A Generalized Cubemap for Encoding 360° VR Videos using Polynomial Approximation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
360° VR videos provide users with an immersive visual experience. To encode 360° VR videos, spherical pixels must be mapped onto a two-dimensional domain to take advantage of the existing video encoding and storage standards. ...
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 ...
Robust Extraction and Simplification of 2D Symmetric Tensor Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
In this work, we propose a controlled simplification strategy for degenerated points in symmetric 2D tensor fields that is based on the topological notion of robustness. Robustness measures the structural stability of 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 ...
Dynamic Visibility-Driven Molecular Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Molecular surface representations are an important tool for the visual analysis of molecular structure and function. In this paper, we present a novel method for the visualization of dynamic molecular surfaces based on the ...
