    • Detecting and Visualizing Rip Current Using Optical Flow 

      Philip, Shweta; Pang, Alex (The Eurographics Association, 2016)
      Rip current are fast moving and narrow currents that are strongest near the beach. They are dangerous not only for novice but also experienced swimmers. Once caught in the current, the flow of the water pulls the person ...
    • Using Icicle Trees to Encode the Hierarchical Structure of Source Code 

      Bacher, Ivan; Namee, Brian Mac; Kelleher, John D. (The Eurographics Association, 2016)
      This paper presents a study which evaluates the use of a tree visualisation (icicle tree) to encode the hierarchical structure of source code. The tree visualisation was combined with a source code editor in order to ...
    • CompaRing: Reducing Costs of Visual Comparison 

      Tominski, Christian (The Eurographics Association, 2016)
      Comparison is a frequent task when analyzing data. In visualization, comparison tasks are naturally carried out based on a visual representation of the data. Visual comparison allows us to gain insight where plain computations ...
    • LMML: Initial Developments of an Integrated Environment for Forensic Data Visualization

      Fighting against crime is paramount to any society, maybe more today than ever before. Tools to fight and elucidate crime are rooted in forensic science. Through the autopsy of a body, we can answer a whole range of questions ...
    • Crystal Glyph: Visualization of Directional Distributions Based on the Cube Map 

      Tong, Xin; Zhang, Huijie; Jacobsen, Chris; Shen, Han-Wei; McCormick, Patrick (The Eurographics Association, 2016)
      High resolution simulations are capable of generating very large vector fields that are expensive to store and analyze. In ad- dition, the velocity fields generated from some particle simulations are not stored on spatial ...
    • Fast 3D Thinning of Medical Image Data based on Local Neighborhood Lookups 

      Post, Tobias; Gillmann, Christina; Wischgoll, Thomas; Hagen, Hans (The Eurographics Association, 2016)
      Three-dimensional thinning is an important task in medical image processing when performing quantitative analysis on structures, such as bones and vessels. For researchers of this domain a fast, robust and easy to access ...
    • Error Estimates for Lagrangian Flow Field Representations 

      Hummel, Mathias; Bujack, Roxana; Joy, Kenneth I.; Garth, Christoph (The Eurographics Association, 2016)
      Computing power outpaces I/O bandwidth in modern high performance computers, which leads to temporal sparsity in flow simulation data. Experiments show that Lagrangian flow representations (where pathlines are retrieved ...
    • Visualization for Understanding Uncertainty in Activation Volumes for Deep Brain Stimulation 

      Hollister, Brad E.; Duffley, Gordon; Butson, Chris; Johnson, Chris; Rosen, Paul (The Eurographics Association, 2016)
      We have created the Neurostimulation Uncertainty Viewer (nuView or nView) tool for exploring data arising from deep brain stimulation (DBS). Simulated volume of tissue activated (VTA), using clinical electrode placements, ...
    • Visualizing Flow Fields Using Fractal Dimensions 

      Shen, Han-Wei; Vasko, Ross; Wenger, Rephael (The Eurographics Association, 2016)
      Streamlines are a popular way of visualizing flow in vector fields. A major challenge in flow field visualization is selecting the streamlines to view. Rendering too many streamlines clutters the visualization and makes ...
    • Interactive Web-based Visualization for Accessibility Mapping of Transportation Networks 

      Schoedon, Alexander; Trapp, Matthias; Hollburg, Henning; Döllner, Jürgen (The Eurographics Association, 2016)
      Accessibility is a fundamental aspect in transportation, routing, and spare-time activity planning concerning traveling in modern cities. In this context, interactive web-based accessibility-map visualization techniques ...
    • VarVis: Visualizing Anatomical Variation in Branching Structures 

      Smit, Noeska; Kraima, Annelot; Jansma, Daniel; deRuiter, Marco; Eisemann, Elmar; Vilanova, Anna (The Eurographics Association, 2016)
      Anatomical variations are naturally-occurring deviations from typical human anatomy. While these variations are considered normal and non-pathological, they are still of interest in clinical practice for medical specialists ...
    • Visualizing Time-Dependent Data Using Dynamic t-SNE 

      Rauber, Paulo E.; Falcão, Alexandre X.; Telea, Alexandru C. (The Eurographics Association, 2016)
      Many interesting processes can be represented as time-dependent datasets. We define a time-dependent dataset as a sequence of datasets captured at particular time steps. In such a sequence, each dataset is composed of ...
    • Space Bundling for Continuous Parallel Coordinates 

      Palmas, Gregorio; Weinkauf, Tino (The Eurographics Association, 2016)
      Continuous Parallel Coordinates (CPC) are a visualization technique used to perform multivariate analysis of different scalar fields defined on the same domain. While classic Parallel Coordinates draws a line for each ...
    • Manifold Visualization via Short Walks 

      Zhao, Yang; Tasoulis, Sotirios; Roos, Teemu (The Eurographics Association, 2016)
      Visualizing low-dimensional non-linear manifolds underlying high-dimensional data is a challenging data analysis problem. Different manifold visualization methods can be characterized by the associated definitions of ...
    • SpaceCuts: Making Room for Visualizations on Maps 

      Buchmüller, Juri; Jäckle, Dominik; Stoffel, Florian; Keim, Daniel A. (The Eurographics Association, 2016)
      Visual map features like streets, rail tracks, or rivers do not provide enough space to visualize multiple attributes on them. Related approaches to solve space issues distort the map with lenses, apply distortion techniques ...
    • Towards Visual Mega-Analysis of Voxel-based Measurement in Brain Cohorts 

      Zhang, Guohao; Kochunov, Peter; Hong, Elliot; Carr, Hamish; Chen, Jian (The Eurographics Association, 2016)
