    • Unsharp Masking, Countershading and Halos: Enhancements or Artifacts? 

      Trentacoste, Matthew; Mantiuk, Rafal; Heidrich, Wolfgang; Dufrot, Florian (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      Countershading is a common technique for local image contrast manipulations, and is widely used both in automatic settings, such as image sharpening and tonemapping, as well as under artistic control, such as in paintings ...
    • Unstructured Light Fields 

      Davis, Abe; Levoy, Marc; Durand, Fredo (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      We present a system for interactively acquiring and rendering light fields using a hand-held commodity camera. The main challenge we address is assisting a user in achieving good coverage of the 4D domain despite the ...
    • Using Signposts for Navigation in Large Graphs 

      May, Thorsten; Steiger, Martin; Davey, James; Kohlhammer, Jörn (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      In this paper we present a new Focus & Context technique for the exploration of large, abstract graphs. Most Focus & Context techniques present context in a visual way. In contrast, our technique uses a symbolic representation: ...
    • Video Panorama for 2D to 3D Conversion 

      Ribera, Roger Blanco i; Choi, Sungwoo; Kim, Younghui; Lee, JungJin; Noh, Junyong (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Accurate depth estimation is a challenging, yet essential step in the conversion of a 2D image sequence to a 3D stereo sequence. We present a novel approach to construct a temporally coherent depth map for each image in a ...
    • Vismon: Facilitating Analysis of Trade-Offs, Uncertainty, and Sensitivity In Fisheries Management Decision Making 

      Booshehrian, Maryam; Möller, Torsten; Peterman, Randall M.; Munzner, Tamara (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      In this design study, we present an analysis and abstraction of the data and task in the domain of fisheries management, and the design and implementation of the Vismon tool to address the identified requirements. Vismon ...
    • Visualization for the Physical Sciences 

      Lipşa, Dan R.; Laramee, Robert S.; Cox, Simon J.; Roberts, Jonathan C.; Walker, Rick; Borkin, Michelle A.; Pfister, Hanspeter (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Close collaboration with other scientific fields is an important goal for the visualization community. Yet engaging in a scientific collaboration can be challenging. The physical sciences, namely astronomy, chemistry, earth ...
    • Visualization of 4D Blood-Flow Fields by Spatiotemporal Hierarchical Clustering 

      Pelt, Roy van; Jacobs, Sander; Romeny, Bart ter Haar; Vilanova, Anna (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Advancements in the acquisition and modeling of flow fields result in unsteady volumetric flow fields of unprecedented quality. An important example is found in the analysis of unsteady blood-flow data. Preclinical research ...
    • Visualization of Advection-Diffusion in Unsteady Fluid Flow 

      Karch, Grzegorz Karol; Sadlo, Filip; Weiskopf, Daniel; Munz, Claus-Dieter; Ertl, Thomas (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Advection has been the standard transport mechanism in flow visualization. Diffusion, in contrast, has not been considered important in visual flow field analysis so far, although it is inherent to many physical processes. ...
    • Visualization of Global Correlation Structures in Uncertain 2D Scalar Fields 

      Pfaffelmoser, Tobias; Westermann, Rüdiger (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Visualizing correlations, i.e., the tendency of uncertain data values at different spatial positions to change contrarily or according to each other, allows inferring on the possible variations of structures in the data. ...
    • Visualizing Motion Data in Virtual Reality: Understanding the Roles of Animation, Interaction, and Static Presentation 

      Coffey, Dane; Korsakov, Fedor; Ewert, Marcus; Hagh-Shenas, Heleh; Thorson, Lauren; Ellingson, Arin; Nuckley, David; Keefe, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present a study of interactive virtual reality visualizations of scientific motions as found in biomechanics experiments. Our approach is threefold. First, we define a taxonomy of motion visualizations organized by the ...
    • Vortex Analysis in Uncertain Vector Fields 

      Otto, Mathias; Theisel, Holger (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present an approach to extract and visualize vortex structures in uncertain vector fields. For this, we generalize the concepts of the most common vortex detectors to uncertain vector fields, namely the λ ...
    • Wake Synthesis For Shallow Water Equation 

      Pan, Zherong; Huang, Jin; Tong, Yiying; Bao, Hujun (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      In fluid animation, wake is one of the most important phenomena usually seen when an object is moving relative to the flow. However, in current shallow water simulation for interactive applications, this effect is greatly ...
    • Wetting Effects in Hair Simulation 

      Rungjiratananon, Witawat; Kanamori, Yoshihiro; Nishita, Tomoyuki (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      There is considerable recent progress in hair simulations, driven by the high demands in computer animated movies. However, capturing the complex interactions between hair and water is still relatively in its infancy. Such ...
    • The World's Languages Explorer: Visual Analysis of Language Features in Genealogical and Areal Contexts 

      Rohrdantz, Christian; Hund, Michael; Mayer, Thomas; Wälchli, Bernhard; Keim, Daniel A. (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      This paper presents a novel Visual Analytics approach that helps linguistic researchers to explore the world's languages with respect to several important tasks: (1) The comparison of manually and automatically extracted ...
