    • SAFE: Structure-aware Facade Editing 

      Dang, Minh; Ceylan, Duygu; Neubert, Boris; Pauly, Mark (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Many man-made objects, in particular building facades, exhibit dominant structural relations such as symmetry and regularity. When editing these shapes, a common objective is to preserve these relations. However, often ...

      Schedl, David C.; Birklbauer, Clemens; Bimber, Oliver (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Capturing exposure sequences to compute high dynamic range (HDR) images causes motion blur in cases of camera movement. This also applies to light-field cameras: frames rendered from multiple blurred HDR lightfield ...
    • Crowd Sculpting: A Space-time Sculpting Method for Populating Virtual Environments

      This paper proposes an interactive rendering method of cloth fabrics under environment lighting. The outgoing radiance from cloth fabrics in the microcylinder model is calculated by integrating the product of the distant ...
    • 4D Video Textures for Interactive Character Appearance 

      Casas, Dan; Volino, Marco; Collomosse, John; Hilton, Adrian (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      animation from a database of 4D actor performance captured in a multiple camera studio. 4D performance capture reconstructs dynamic shape and appearance over time but is limited to free-viewpoint video replay of the same ...
    • Adaptive Texture Space Shading for Stochastic Rendering 

      Andersson, Magnus; Hasselgren, Jon; Toth, Robert; Akenine-Möller, Tomas (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      When rendering effects such as motion blur and defocus blur, shading can become very expensive if done in a naïve way, i.e. shading each visibility sample. To improve performance, previous work often decouple shading from ...
    • Thumbnail Galleries for Procedural Models 

      Lienhard, Stefan; Specht, Matthias; Neubert, Boris; Pauly, Mark; Müller, Pascal (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Procedural modeling allows for the generation of innumerable variations of models from a parameterized, conditional or stochastic rule set. Due to the abstractness, complexity and stochastic nature of rule sets, it is often ...
    • Efficient Monte Carlo Rendering with Realistic Lenses 

      Hanika, Johannes; Dachsbacher, Carsten (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In this paper we present a novel approach to simulate image formation for a wide range of real world lenses in the Monte Carlo ray tracing framework. Our approach sidesteps the overhead of tracing rays through a system of ...
    • Optimizing BRDF Orientations for the Manipulation of Anisotropic Highlights 

      Raymond, Boris; Guennebaud, Gaël; Barla, Pascal; Pacanowski, Romain; Granier, Xavier (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      This paper introduces a system for the direct editing of highlights produced by anisotropic BRDFs, which we call anisotropic highlights. We first provide a comprehensive analysis of the link between the direction of ...
    • Laplacian Colormaps: a Framework for Structure-preserving Color Transformations 

      Eynard, Davide; Kovnatsky, Artiom; Bronstein, Michael M. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Mappings between color spaces are ubiquitous in image processing problems such as gamut mapping, decolorization, and image optimization for color-blind people. Simple color transformations often result in information loss ...
    • A Randomized Algorithm for Natural Object Colorization 

      Jin, Sou-Young; Choi, Ho Jin; Tai, Yu-Wing (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Natural objects often contain vivid color distribution with wide variety of colors. Conventional colorization techniques, on the other hand, produce colors that are relatively flat with little color variation. In this ...
    • Interactive Motion Mapping for Real-time Character Control 

      Rhodin, Helge; Tompkin, James; Kim, Kwang In; Varanasi, Kiran; Seidel, Hans-Peter; Theobalt, Christian (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Abstract It is now possible to capture the 3D motion of the human body on consumer hardware and to puppet in real time skeleton-based virtual characters. However, many characters do not have humanoid skeletons. Characters ...

      Vasa, Libor; Brunnett, Guido (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Lossy compression of motion capture data can alleviate the problems of efficient storage and transmission by exploiting the redundancy and the superfluous precision of the data. When considering the acceptable amount of ...
