    • Maximum Entropy Summary Trees 

      Karloff, Howard; Shirley, Kenneth E. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Given a very large, node-weighted, rooted tree on, say, n nodes, if one has only enough space to display a knode summary of the tree, what is the most informative way to draw the tree? We define a type of weighted tree ...
    • Evaluation of Attention-Guiding Video Visualization 

      Kurzhals, Kuno; Höferlin, Markus; Weiskopf, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We investigate four different variants of attention-guiding video visualization techniques that aim to help users distribute their attention equally among potential objects of interest: bounding box visualization, ...

      Analysis of chemical constituents from mass spectrometry of aerosols involves non-negative matrix factorization, an approximation of high-dimensional data in lower-dimensional space. The associated optimization problem is ...
    • Mass-Dependent Integral Curves in Unsteady Vector Fields 

      Günther, Tobias; Kuhn, Alexander; Kutz, Benjamin; Theisel, Holger (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 

      Ferreira, Nivan; Klosowski, James T.; Scheidegger, Carlos E.; Silva, Cláudio T. (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 ...
    • EvalBench: A Software Library for Visualization Evaluation 

      Aigner, Wolfgang; Hoffmann, Stephan; Rind, Alexander (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      It is generally acknowledged in visualization research that it is necessary to evaluate visualization artifacts in order to provide empirical evidence on their effectiveness and efficiency as well as their usability and ...
    • Progressive High-Quality Response Surfaces for Visually Guided Sensitivity Analysis 

      Demir, Ismael; Westermann, Rüdiger (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper we present a technique which allows us to perform high quality and progressive response surface prediction from multidimensional input samples in an efficient manner. We utilize kriging interpolation to ...
    • Evolutionary Visual Exploration: Evaluation With Expert Users 

      Boukhelifa, Nadia; Cancino, Waldo; Bezerianos, Anastasia; Lutton, Evelyne (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present an Evolutionary Visual Exploration (EVE) system that combines visual analytics with stochastic optimisation to aid the exploration of multidimensional datasets characterised by a large number of possible views ...
    • Constructing Isosurfaces with Sharp Edges and Corners using Cube Merging 

      Bhattacharya, Arindam; Wenger, Rephael (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      A number of papers present algorithms to construct isosurfaces with sharp edges and corners from hermite data, i.e. the exact surface normals at the exact intersection of the surface and grid edges. We discuss some fundamental ...
    • Complexity Plots 

      Thiyagalingam, Jeyarajan; Walton, Simon; Duffy, Brian; Trefethen, Anne; Chen, Min (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 ...
    • Nonparametric Models for Uncertainty Visualization 

      Pöthkow, Kai; Hege, Hans-Christian (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, ...
    • HiFiVE: A Hilbert Space Embedding of Fiber Variability Estimates for Uncertainty Modeling and Visualization 

      Schultz, Thomas; Schlaffke, Lara; Schölkopf, Bernhard; Schmidt-Wilcke, Tobias (The Eurographics Association and Blackwell Publishing Ltd., 2013)

    • Visualizing Large-scale Parallel Communication Traces Using a Particle Animation Technique 

      Sigovan, Carmen M.; Muelder, Chris W.; Ma, Kwan-Liu (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 ...
