High-Performance Motion Correction of Fetal MRI
(The Eurographics Association, 2016)
Fetal Magnetic Resonance Imaging (MRI) shows promising results for pre-natal diagnostics. The detection of potentially lifethreatening abnormalities in the fetus can be difficult with ultrasound alone. MRI is one of the ...
Toward Visualizing Subjective Uncertainty: A Conceptual Framework Addressing Perceived Uncertainty through Action Redundancy
(The Eurographics Association, 2018)
Uncertainty is usually technically defined with associated metrics by visualization researchers. Next to this rather objective description, there is a subjective notion to uncertainty considering human experiences eliciting ...
Visual Analytics-enabled Bayesian Network Approach to Reasoning about Public Camera Data
(The Eurographics Association, 2018)
The Visual Analytics (VA) approach has become an important tool for gaining insights on various data sets. Thus, significant research has been conducted to integrate statistical methods in the interactive environment of ...
On the Reproducibility of VisRuption: A Tool for Intuitive and Efficient Visualization of Airline Disruption Data
(The Eurographics Association, 2015)
Managing the vast amount of resources and processes of large airlines with several hundred aircraft and several thousand operated flights per day is a very complex task and makes computer-aided operation irreplaceable. ...
Uncertainty and Reproducibility in Medical Visualization
(The Eurographics Association, 2016)
The medical visualization pipeline is affected by various sources of uncertainty. Many errors may occur and several assumptions are made in the various processing steps from the image acquisition to the rendering of the ...
A Mixed Approach for the Evaluation of a Guided Exploratory Visualization System
(The Eurographics Association, 2015)
We summarise and reflect upon our experience in evaluating a guided exploratory visualization system. Our system guides users in their exploration of multidimensional datasets to pertinent views of their data, where the ...
Uni- and Multi-modal Uncertainty Visualization in 2D Scalar Field Ensembles
(The Eurographics Association, 2019)
The aim of uncertainty-aware scalar field visualization is to convey the most likely case, but also the uncertainty associated with it. In scientific simulations, uncertainty can be modeled using an ensemble approach. ...
From a User Study to a Valid Claim: How to Test Your Hypothesis and Avoid Common Pitfalls
(The Eurographics Association, 2017)
The evaluation of visualization methods or designs often relies on user studies. Apart from the difficulties involved in the design of the study itself, the existing mechanisms to obtain sound conclusions are often unclear. ...
Guidelines and Recommendations for the Evaluation of New Visualization Techniques by Means of Experimental Studies
(The Eurographics Association, 2017)
This paper addresses important issues in the evaluation of new visualization techniques. It describes the principle of quantitative research in general and presents the idea of experimental studies. The goal of experimental ...
Experiences on Validation of Multi-Component System Simulations for Medical Training Applications
(The Eurographics Association, 2016)
In the simulation of multi-component systems, we often encounter a problem with a lack of ground-truth data. This situation makes the validation of our simulation methods and models a difficult task. In this work we present ...
