    • Reevaluating Reconstruction Filters for Path‐Searching Tasks in 3D 

      Roberts, D. A. T.; Ivrissimtzis, I. (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      In this paper, we present an experiment on stereoscopic direct volume rendering, aiming at understanding the relationship between the choice of reconstruction filter and participant performance on tasks requiring spatial ...

    • Scalable Feature‐Preserving Irregular Mesh Coding 

      El Sayeh Khalil, J.; Munteanu, A.; Denis, L.; Lambert, P.; Walle, R. (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper presents a novel wavelet‐based transform and coding scheme for irregular meshes. The transform preserves geometric features at lower resolutions by adaptive vertex sampling and retriangulation, resulting in more ...

    • Spectral Processing of Tangential Vector Fields 

      Brandt, Christopher; Scandolo, Leonardo; Eisemann, Elmar; Hildebrandt, Klaus (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We propose a framework for the spectral processing of tangential vector fields on surfaces. The basis is a Fourier‐type representation of tangential vector fields that associates frequencies with tangential vector fields. ...

    • Stress‐Constrained Thickness Optimization for Shell Object Fabrication 

      Zhao, Haiming; Xu, Weiwei; Zhou, Kun; Yang, Yin; Jin, Xiaogang; Wu, Hongzhi (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present an approach to fabricate shell objects with thickness parameters, which are computed to maintain the user‐specified structural stability. Given a boundary surface and user‐specified external forces, we optimize ...

    • Structure‐Texture Decomposition of Images with Interval Gradient 

      Lee, Hyunjoon; Jeon, Junho; Kim, Junho; Lee, Seungyong (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper presents a novel filtering‐based method for decomposing an image into structures and textures. Unlike previous filtering algorithms, our method adaptively smooths image gradients to filter out textures from ...

    • A Survey of Cardiac 4D PC‐MRI Data Processing 

      Köhler, Benjamin; Born, Silvia; van Pelt, Roy F. P.; Hennemuth, Anja; Preim, Uta; Preim, Bernhard (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Cardiac four‐dimensional phase‐contrast magnetic resonance imaging (4D PC‐MRI) acquisitions have gained increasing clinical interest in recent years. They allow to non‐invasively obtain extensive information about ...

    • Time‐Continuous Quasi‐Monte Carlo Ray Tracing 

      Gribel, C.J.; Akenine‐Möller, T. (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Domain‐continuous visibility determination algorithms have proved to be very efficient at reducing noise otherwise prevalent in stochastic sampling. Even though they come with an increased overhead in terms of geometrical ...

    • Visual Quantification of the Circle of Willis: An Automated Identification and Standardized Representation 

      Miao, H.; Mistelbauer, G.; Našel, C.; Gröller, M. E. (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper presents a method for the visual quantification of cerebral arteries, known as the Circle of Willis (CoW). It is an arterial structure with the responsibility of supplying the brain with blood, however, dysfunctions ...

    • Visual Text Analysis in Digital Humanities 

      Jänicke, S.; Franzini, G.; Cheema, M. F.; Scheuermann, G. (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      In 2005, Franco Moretti introduced Distant Reading to analyse entire literary text collections. This was a rather revolutionary idea compared to the traditional Close Reading, which focuses on the thorough interpretation ...

    • A Visualization‐Based Analysis System for Urban Search & Rescue Mission Planning Support 

      Bock, Alexander; Svensson, Åsa; Kleiner, Alexander; Lundberg, Jonas; Ropinski, Timo (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We propose a visualization system for incident commanders (ICs) in urban search and rescue scenarios that supports path planning in post‐disaster structures. Utilizing point cloud data acquired from unmanned robots, we ...

    • Visualizing Group Structures in Graphs: A Survey 

      Vehlow, Corinna; Beck, Fabian; Weiskopf, Daniel (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Graph visualizations encode relationships between objects. Abstracting the objects into group structures provides an overview of the data. Groups can be disjoint or overlapping, and might be organized hierarchically. ...
