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 ...
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 ...
Visual Analysis of Charge Flow Networks for Complex Morphologies
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
In the field of organic electronics, understanding complex material morphologies and their role in efficient charge transport in solar cells is extremely important. Related processes are studied using the Ising model and ...
