Total Euler Characteristic as a Noise Measure to aid Transfer Function Design
(The Eurographics Association, 2013)
For image-based, semi- or fully automated design of transfer functions for direct volume rendering, it is beneficial to have an estimation of the noise level in the rendered image. A topology-motivated noise measure is ...
Hierarchical Clustering with Multiple-Height Branch-Cut Applied to Short Time-Series Gene Expression Data
(The Eurographics Association, 2016)
Rigid adherence to pre-specified thresholds and static graphical representations can lead to incorrect decisions on merging of clusters. As an alternative to existing automated or semi-automated methods, we developed a ...
Interactive Comparative Visualization of Multimodal Brain Tumor Segmentation Data
(The Eurographics Association, 2013)
We present a visualization system for the analysis of multi-modal segmentation data of brain tumors. Our system is designed to allow researchers and doctors a further investigation of segmented tumor data beyond a quantitative ...
Visualization of Neural Network Predictions for Weather Forecasting
(The Eurographics Association, 2017)
Recurrent neural networks are prime candidates for learning relationships and evolutions in multi-dimensional time series data. The performance of such a network is judged by the loss function, which is aggregated into a ...
See-through Visualisation for Training and Assessing Unsighted Physical Examinations
(The Eurographics Association, 2017)
Objective: Motivated by the limitations of being unable to provide feedback and adequately assess technical skills whilst training unsighted physical examinations, such as Digital Rectal Examinations (DRE), we present a ...
Visualizing Contour Distributions in 2D Ensemble Data
(The Eurographics Association, 2013)
Overlaid plots of iso-contours in individual members of a scalar ensemble field are a popular concept to visualize the data uncertainty. However, such plots do not allow inferring on the spatial cumulative probability ...
Determining and Visualizing Potential Sources of Floods
(The Eurographics Association, 2013)
In this paper, we visually analyze spatio-temporal patterns of different hydrologic parameters relevant for flooding. On the basis of data from climate simulations with a high resolution regional atmosphere model, several ...
Structure-aware Stylization of Mountainous Terrains
(The Eurographics Association, 2017)
We present a method for the stylization of mountainous terrains that allows creating abstract representations in different rendering styles. Our method consists of two major components: structure-aware terrain filtering ...
Power Efficiency of Volume Raycasting on Mobile Devices
(The Eurographics Association, 2017)
Power efficiency is one of the most important factors for the development of compute-intensive applications in the mobile domain. In this work, we evaluate and discuss the power consumption of a direct volume rendering app ...
Per-Fragment Image-based Flow Visualization using Interactive Surface Extraction from Unstructured Grids
(The Eurographics Association, 2014)
We present a method for image-based visualization of flow fields on unstructured grids. For interactive explorationof flow data from CFD simulations, we combine GPU-accelerated surface extraction methods and line ...
