      Li, Yuqi; Majumder, Aditi; Lu, Dongming; Gopi, Meenakshisundaram (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Many works focus on multi-spectral capture and analysis, but multi-spectral display still remains a challenge. Most prior works on multi-primary displays use ad-hoc narrow band primaries that assure a larger color gamut, ...
    • Continuous Matching via Vector Field Flow 

      Corman, Etienne; Ovsjanikov, Maks; Chambolle, Antonin (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a new method for non-rigid shape matching designed to enforce continuity of the resulting correspondence. Our method is based on the recently proposed functional map representation, which allows efficient ...
    • Contrast-Enhanced Black and White Images 

      Li, Hua; Mould, David (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      This paper investigates contrast enhancement as an approach to tone reduction, aiming to convert a photograph to black and white. Using a filter-based approach to strengthen contrast, we avoid making a hard decision about ...
    • Controller Design for Multi‐Skilled Bipedal Characters 

      Firmin, M.; Panne, M. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Developing motions for simulated humanoids remains a challenging problem. While there exists a multitude of approaches, few of these are reimplemented or reused by others. The predominant focus of papers in the area remains ...
    • Convolution Filtering of Continuous Signed Distance Fields for Polygonal Meshes 

      Sanchez, Mathieu; Fryazinov, Oleg; Fayolle, Pierre‐Alain; Pasko, Alexander (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Signed distance fields obtained from polygonal meshes are commonly used in various applications. However, they can have discontinuities causing creases to appear when applying operations such as blending or metamorphosis. ...
    • CPH: A Compact Representation for Hierarchical Meshes Generated by Primal Refinement 

      Untereiner, L.; Kraemer, P.; Cazier, D.; Bechmann, D. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present CPH (): a compact representation of the hierarchical connectivity of surface and volume manifold meshes generated through primal subdivision refinements. CPH is consistently defined in several dimensions and ...
    • A Cut-Cell Geometric Multigrid Poisson Solver for Fluid Simulation 

      Weber, Daniel; Mueller-Roemer, Johannes; Stork, André; Fellner, Dieter W. (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a novel multigrid scheme based on a cut-cell formulation on regular staggered grids which generates compatible systems of linear equations on all levels of the multigrid hierarchy. This geometrically motivated ...
    • Data-driven Evaluation of Visual Quality Measures 

      Sedlmair, Michael; Aupetit, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Visual quality measures seek to algorithmically imitate human judgments of patterns such as class separability, correlation, or outliers. In this paper, we propose a novel data-driven framework for evaluating such measures. ...
