      Bacteria and viruses are transmitted among patients in the hospital. Infection control experts develop strategies for infection control. Currently, this is done mostly manually, which is time-consuming and error-prone. ...
    • Visual Analysis of Advanced Manufacturing Simulations 

      Wörner, M.; Ertl, T. (The Eurographics Association, 2011)
      Today's manufacturing companies are faced with requests for highly customer-specific products that come in numerous variants but small numbers of units per variant. Therefore, their manufacturing processes need to be ...
    • Visual Analysis of Degree-of-Interest Functions to Support Selection Strategies for Instance Labeling 

      Bernard, Jürgen; Hutter, Marco; Ritter, Christian; Lehmann, Markus; Sedlmair, Michael; Zeppelzauer, Matthias (The Eurographics Association, 2019)
      Manually labeling data sets is a time-consuming and expensive task that can be accelerated by interactive machine learning and visual analytics approaches. At the core of these approaches are strategies for the selection ...
    • Visual Analysis of Expert Systems for Smart Grid Monitoring 

      Steiger, M.; May, T.; Davey, J.; Kohlhammer, J. (The Eurographics Association, 2013)
      This application paper introduces the combination of an expert system with a visualization system, specifically designed for SmartGrid control rooms. It supports operators in the efficient monitoring of electric grids with ...
    • Visual Analysis of Explicit Opinion and News Bias in German Soccer Articles 

      Oelke, Daniela; Geißelmann, Benno; Keim, Daniel A. (The Eurographics Association, 2012)
      Most state-of-the-art opinion and sentiment analysis techniques were developed for customer feedback data or reviews. Applying them to another domain is often not possible because the algorithms are based on the assumption ...
    • Visual Analysis of Geo-spatial Data in 3D Terrain Environments using Focus+Context 

      Richter, Christian; Dübel, Steve; Schumann, Heidrun (The Eurographics Association, 2017)
      Visual analysis of geo-spatial data represented within a three-dimensional frame of reference is a challenging task. Focus+ Context is a common concept that aids this process. This paper addresses the question, how ...
    • Visual Analysis of Optical Coherence Tomography Data in Ophthalmology 

      Röhlig, Martin; Rosenthal, Paul; Schmidt, Christoph; Schumann, Heidrun; Stachs, Oliver (The Eurographics Association, 2017)
      Optical coherence tomography (OCT) enables noninvasive high-resolution 3D imaging of the human retina and thus, plays a fundamental role in detecting a wide range of ocular diseases. Despite OCT's diagnostic value, managing ...
    • Visual Analysis of Public Transport Vehicle Movement 

      Wörner, Michael; Ertl, Thomas (The Eurographics Association, 2012)
      Public transport vehicles record detailed operational logs. In major networks, this quickly amounts to massive datasets. Traditionally, these are analysed only using statistical tools, yet they show great potential for the ...
    • Visual Analysis of Relations in Attributed Time-Series Data 

      Steiger, Martin; Bernard, Jürgen; Schader, Philipp; Kohlhammer, Jörn (The Eurographics Association, 2015)
      In this paper, we present visual-interactive techniques for revealing relations between two co-existing multivariate feature spaces. Such data is generated, for example, by sensor networks characterized by a set of ...
