  • Energy-scale Aware Feature Extraction for Flow Visualization 

    Pobitzer, Armin; Tutkun, Murat; Anreassen, Øyvind; Fuchs, Raphael; Peikert, Ronald; Hauser, Helwig (Blackwell Publishing Ltd., 2011)
    In the visualization of flow simulation data, feature detectors often tend to result in overly rich response, making some sort of filtering or simplification necessary to convey meaningful images. In this paper we present ...

  • Filtering of FTLE for Visualizing Spatial Separation in Unsteady 3D Flow 

    Pobitzer, Armin; Peikert, Ronald; Fuchs, Raphael; Theisel, Holger; Hauser, Helwig (Springer, 2012)
    In many cases, feature detection for flow visualization is structured in two phases: first candidate identification, and then filtering. With this paper, we propose to use the directional information contained in the ...

  • Interactive Visual Analysis of Time-dependent Flows: Physics- and Statistics-based Semantics 

    Pobitzer, Armin (The University of Bergen, 2012-06-22)
    With the increasing use of numerical simulations in the fluid mechanics community in recent years flow visualization increasingly gains importance as an advanced analysis tool for the simulation output. Up to now, ...

  • The State of the Art in Topology-based Visualization of Unsteady Flow 

    Pobitzer, Armin; Peikert, Ronald; Fuchs, Raphael; Schindler, Benjamin; Kuhn, Alexander; Theisel, Holger; Matković, Krešimir; Hauser, Helwig (Blackwell Publishing Ltd., 2011)
    Vector fields are a common concept for the representation of many different kinds of flow phenomena in science and engineering. Methods based on vector field topology are known for their convenience for visualizing and ...

  • A Statistics-based Dimension Reduction of the Space of Path Line Attributes for Interactive Visual Flow Analysis 

    Pobitzer, Armin; Lež, Alan; Matković, Krešimir; Hauser, Helwig (IEEE, 2012)
    Recent work has shown the great potential of interactive flow analysis by the analysis of path lines. The choice of suitable attributes, describing the path lines, is, however, still an open question. This paper addresses ...
