    • Planar Shape Detection and Regularization in Tandem 

      Oesau, Sven; Lafarge, Florent; Alliez, Pierre (Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a method for planar shape detection and regularization from raw point sets. The geometric modelling and processing of man‐made environments from measurement data often relies upon robust detection of planar ...

    • Practical Low‐Cost Recovery of Spectral Power Distributions 

      Alvarez‐Cortes, Sara; Kunkel, Timo; Masia, Belen (Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Measuring the spectral power distribution of a light source, that is, the emission as a function of wavelength, typically requires the use of spectrophotometers or multi‐spectral cameras. Here, we propose a low‐cost system ...

    • Projective Blue‐Noise Sampling 

      Reinert, Bernhard; Ritschel, Tobias; Seidel, Hans‐Peter; Georgiev, Iliyan (Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We propose projective blue‐noise patterns that retain their blue‐noise characteristics when undergoing one or multiple projections onto lower dimensional subspaces. These patterns are produced by extending existing methods, ...

    • Real‐Time Rendering Techniques with Hardware Tessellation 

      Nießner, M.; Keinert, B.; Fisher, M.; Stamminger, M.; Loop, C.; Schäfer, H. (Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Graphics hardware has progressively been optimized to render more triangles with increasingly flexible shading. For highly detailed geometry, interactive applications restricted themselves to performing transforms on fixed ...

    • Robust Cardiac Function Assessment in 4D PC‐MRI Data of the Aorta and Pulmonary Artery 

      Köhler, Benjamin; Preim, Uta; Grothoff, Matthias; Gutberlet, Matthias; Fischbach, Katharina; Preim, Bernhard (Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Four‐dimensional phase‐contrast magnetic resonance imaging (4D PC‐MRI) allows the non‐invasive acquisition of time‐resolved, 3D blood flow information. Stroke volumes (SVs) and regurgitation fractions (RFs) are two of the ...

    • State of the Art in Artistic Editing of Appearance, Lighting and Material 

      Schmidt, Thorsten‐Walther; Pellacini, Fabio; Nowrouzezahrai, Derek; Jarosz, Wojciech; Dachsbacher, Carsten (Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Mimicking the appearance of the real world is a longstanding goal of computer graphics, with several important applications in the feature film, architecture and medical industries. Images with well‐designed shading are ...

    • The State‐of‐the‐Art of Set Visualization 

      Alsallakh, Bilal; Micallef, Luana; Aigner, Wolfgang; Hauser, Helwig; Miksch, Silvia; Rodgers, Peter (Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Sets comprise a generic data model that has been used in a variety of data analysis problems. Such problems involve analysing and visualizing set relations between multiple sets defined over the same collection of elements. ...

    • A Survey of Geometric Analysis in Cultural Heritage 

      Pintus, Ruggero; Pal, Kazim; Yang, Ying; Weyrich, Tim; Gobbetti, Enrico; Rushmeier, Holly (Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a review of recent techniques for performing geometric analysis in cultural heritage (CH) applications. The survey is aimed at researchers in the areas of computer graphics, computer vision and CH computing, as ...

    • Variational Image Fusion with Optimal Local Contrast 

      Hafner, David; Weickert, Joachim (Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In this paper, we present a general variational method for image fusion. In particular, we combine different images of the same subject to a single composite that offers optimal exposedness, saturation and local contrast. ...
