• Curve Density Estimates 

      Lampe, Ove Daae; Hauser, Helwig (Peer reviewed; Journal article, 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, multiple ...
    • Curve-Centric Volume Reformation for Comparative Visualization 

      Lampe, Ove Daae; Correa, Carlos; Ma, Kwan-Liu; Hauser, Helwig (Peer reviewed; Journal article, 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 (Peer reviewed; Journal article, 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 (Peer reviewed; Journal article, 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 multi-faceted scientific data 

      Kehrer, Johannes (Doctoral thesis, 2011-05-27)
      Visualization plays an important role in exploring, analyzing and presenting large and heterogeneous scientific data that arise in many disciplines of medicine, research, engineering, and others. We can see that model and ...
    • Interactive Visual Analysis of Process Data 

      Lampe, Ove Daae (Doctoral thesis, 2011-11-30)
      Data gathered from processes, or process data, contains many different aspects that a visualization system should also convey. Aspects such as, temporal coherence, spatial connectivity, streaming data, and the need for ...
    • Interactive Visual Analysis of Time-dependent Flows: Physics- and Statistics-based Semantics 

      Pobitzer, Armin (Doctoral thesis, 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, flow ...
    • Interactive Visualization of Streaming Data with Kernel Density Estimation 

      Lampe, Ove Daae; Hauser, Helwig (Chapter; Peer reviewed, 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 for ...
    • 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 (Peer reviewed; Journal article, 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 (Peer reviewed; Journal article, 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 ...
