AOI Rivers for Visualizing Dynamic Eye Gaze Frequencies
(The Eurographics Association and Blackwell Publishing Ltd., 2013)It is difficult to explore and analyze eye gaze trajectories for commonly applied visual task solution strategies because such data shows complex spatio-temporal structure. In particular, the traditional eye gaze plots of ... -
Visualizing Interchange Patterns in Massive Movement Data
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Massive amount of movement data, such as daily trips made by millions of passengers in a city, are widely available nowadays. They are a highly valuable means not only for unveiling human mobility patterns, but also for ... -
Spatially Efficient Design of Annotated Metro Maps
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Annotating metro maps with thumbnail photographs is a commonly used technique for guiding travelers. However, conventional methods usually suffer from small labeling space around the metro stations, especially when they ... -
AmniVis - A System for Qualitative Exploration of Near-Wall Hemodynamics in Cerebral Aneurysms
(The Eurographics Association and Blackwell Publishing Ltd., 2013)The qualitative exploration of near-wall hemodynamics in cerebral aneurysms provides important insights for risk assessment. For instance, a direct relation between complex flow patterns and aneurysm formation could be ... -
Comparative Visualization of Tracer Uptake in In Vivo Small Animal PET/CT Imaging of the Carotid Arteries
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Cardiovascular diseases are the main cause of death in the western world. Medical research on atherosclerosis is therefore of great interest and a very active research topic. We present a visualization system that supports ... -
Vessel Visualization using Curvicircular Feature Aggregation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Radiological investigations are common medical practice for the diagnosis of peripheral vascular diseases. Existing visualization methods such as Curved Planar Reformation (CPR) depict calcifications on vessel walls to ... -
Visualizing Robustness of Critical Points for 2D Time-Varying Vector Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Analyzing critical points and their temporal evolutions plays a crucial role in understanding the behavior of vector fields. A key challenge is to quantify the stability of critical points: more stable points may represent ... -
Mass-Dependent Integral Curves in Unsteady Vector Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Recent research in flow visualization is focusing on the analysis of time-dependent, but mass-less particles. However, in many application scenarios, the mass of particles - and their resulting inertia - is essential in ... -
Vector Field k-Means: Clustering Trajectories by Fitting Multiple Vector Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Scientists study trajectory data to understand trends in movement patterns, such as human mobility for traffic analysis and urban planning. In this paper, we introduce a novel trajectory clustering technique whose central ... -
Small Multiples, Large Singles: A New Approach for Visual Data Exploration
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a novel visual exploration method based on small multiples and large singles for effective and efficient data analysis. Users are enabled to explore the state space by offering multiple alternatives from the ... -
Gestaltlines
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose a general technique to visualize multivariate data sequences. It is based on a symbiotic combination of three powerful concepts from information visualization: sparklines, glyphs and gestalt theory. By visualizing ... -
Scale-Stack Bar Charts
(The Eurographics Association and Blackwell Publishing Ltd., 2013)It is difficult to create appropriate bar charts for data that cover large value ranges. The usual approach for these cases employs a logarithmic scale, which, however, suffers from issues inherent to its non-linear mapping: ... -
TAMRESH - Tensor Approximation Multiresolution Hierarchy for Interactive Volume Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Interactive visual analysis of large and complex volume datasets is an ongoing and challenging problem. We tackle this challenge in the context of state-of-the-art out-of-core multiresolution volume rendering by introducing ... -
A Visual Approach to Investigating Shared and Global Memory Behavior of CUDA Kernels
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present an approach to investigate the memory behavior of a parallel kernel executing on thousands of threads simultaneously within the CUDA architecture. Our top-down approach allows for quickly identifying any significant ... -
Visualizing Large-scale Parallel Communication Traces Using a Particle Animation Technique
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Large-scale scientific simulations require execution on parallel computing systems in order to yield useful results in a reasonable time frame. But parallel execution adds communication overhead. The impact that this ... -
Nonparametric Models for Uncertainty Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)An uncertain (scalar, vector, tensor) field is usually perceived as a discrete random field with a priori unknown probability distributions. To compute derived probabilities, e.g. for the occurrence of certain features, ... -
Complexity Plots
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In this paper, we present a novel visualization technique for assisting the observation and analysis of algorithmic complexity. In comparison with conventional line graphs, this new technique is not sensitive to the units ... -
HiFiVE: A Hilbert Space Embedding of Fiber Variability Estimates for Uncertainty Modeling and Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Obtaining reproducible fiber direction estimates from diffusion MRI is crucial for successful fiber tracking. Modeling and visualizing the probability distribution of the inferred fiber directions is an important step in ... -
