  • Curve Density Estimates 

    Lampe, Ove Daae; Hauser, Helwig (Blackwell Publishing Ltd., 2011-06-28)
    In this work, we present a technique based on kernel density estimation for rendering smooth curves. With this approach, we produce uncluttered and expressive pictures, revealing frequency information about one, or, ...

  • Curve-Centric Volume Reformation for Comparative Visualization 

    Lampe, Ove Daae; Correa, Carlos; Ma, Kwan-Liu; Hauser, Helwig (IEEE, 2009-10-11)
    We present two visualization techniques for curve-centric volume reformation with the aim to create compelling comparative visualizations. A curve-centric volume reformation deforms a volume, with regards to a curve in ...

  • 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 ...

  • A Hierarchical Splitting Scheme to Reveal Insight into Highly Self-Occluded Integral Surfaces 

    Brambilla, Andrea; Viola, Ivan; Hauser, Helwig (Václav Skala - UNION Agency, 2012)
    In flow visualization, integral surfaces are of particular interest for their ability to describe trajectories of massless particles. In areas of swirling motion, integral surfaces can become very complex and difficult ...

  • Illustrative Flow Visualization: State of the Art, Trends and Challenges 

    Brambilla, Andrea; Carnecky, Robert; Peikert, Robert; Viola, Ivan; Hauser, Helwig (The Eurographics Association, 2012)
    Flow visualization is a well established branch of scientific visualization and it currently represents an invaluable resource to many fields, like automotive design, meteorology and medical imaging. Thanks to the ...

  • Integrated Multi-aspect Visualization of 3D Fluid Flows 

    Brambilla, Andrea; Andreassen, Øyvind; Hauser, Helwig (The Eurographics Association, 2013)
    The motion of a fluid is affected by several intertwined flow aspects. Analyzing one aspect at a time can only yield partial information about the flow behavior. More details can be revealed by studying their interactions. ...
  • Interactive Visualization of Streaming Data with Kernel Density Estimation 

    Lampe, Ove Daae; Hauser, Helwig (IEEE, 2011)
    In this paper, we discuss the extension and integration of the statistical concept of Kernel Density Estimation (KDE) in a scatterplotlike visualization for dynamic data at interactive rates. We present a line kernel ...

  • Interactively illustrating polymerization using three-level model fusion 

    Kolesar, Ivan; Parulek, Julius; Viola, Ivan; Bruckner, Stefan; Stavrum, Anne-Kristin; Hauser, Helwig (BioMed Central, 2014-10-14)
    Background: Research in cell biology is steadily contributing new knowledge about many aspects of physiological processes, both with respect to the involved molecular structures as well as their related function. Illustrations ...

  • 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 ...
