    • A Spectral BSSRDF for Shading Human Skin 

      Donner, Craig; Jensen, Henrik Wann (The Eurographics Association, 2006)
      We present a novel spectral shading model for human skin. Our model accounts for both subsurface and surface scattering, and uses only four parameters to simulate the interaction of light with human skin. The four parameters ...
    • Practical, Real-time Studio Matting using Dual Imagers 

      McGuire, Morgan; Matusik, Wojciech; Yerazunis, William (The Eurographics Association, 2006)
      This paper presents a practical system for capturing high-resolution video mattes using cameras that contain two imagers on one optical axis. The dual imagers capture registered frames that differ only by defocus or ...
    • Segmentation-Based 3D Artistic Rendering 

      Kolliopoulos, Alexander; Wang, Jack M.; Hertzmann, Aaron (The Eurographics Association, 2006)
      This paper introduces segmentation-based 3D non-photorealistic rendering, in which 3D scenes are rendered as a collection of 2D image segments. Segments abstract out unnecessary detail and provide a basis for defining new ...
    • Texture Replacement of Garments in Monocular Video 

      Scholz, Volker; Magnor, Marcus (The Eurographics Association, 2006)
      In this paper, we present a video processing algorithm for texture replacement of moving garments in monocular video recordings. We use a color-coded pattern which encodes texture coordinates within a local neighborhood ...
    • Efficient Wavelet Rotation for Environment Map Rendering 

      Wang, Rui; Ng, Ren; Luebke, David; Humphreys, Greg (The Eurographics Association, 2006)
      Real-time shading with environment maps requires the ability to rotate the global lighting to each surface point's local coordinate frame. Although extensive previous work has studied rotation of functions represented by ...
    • Relighting Human Locomotion with Flowed Reflectance Fields 

      Einarsson, Per; Chabert, Charles-Felix; Jones, Andrew; Ma, Wan-Chun; Lamond, Bruce; Hawkins, Tim; Bolas, Mark; Sylwan, Sebastian; Debevec, Paul (The Eurographics Association, 2006)
      We present an image-based approach for capturing the appearance of a walking or running person so they can be rendered realistically under variable viewpoint and illumination. In our approach, a person walks on a treadmill ...
    • Bidirectional Instant Radiosity 

      Segovia, Benjamin; Iehl, Jean Claude; Mitanchey, Richard; Péroche, Bernard (The Eurographics Association, 2006)
      This paper presents a new sampling strategy to achieve interactive global illumination on one commodity computer. The goal is to propose an efficient numerical stochastic scheme which can be well adapted to a fast rendering ...
    • Automatic Multiperspective Images 

      Román, Augusto; Lensch, Hendrik P. A. (The Eurographics Association, 2006)
      Multiperspective images generated from a collection of photographs or a videostream can be used to effectively summarize long, roughly planar scenes such as city streets. The final image will span a larger field of view ...
    • Spatio-Angular Resolution Tradeoffs in Integral Photography 

      Georgeiv, Todor; Zheng, Ke Colin; Curless, Brian; Salesin, David; Nayar, Shree; Intwala, Chintan (The Eurographics Association, 2006)
      An integral camera samples the 4D light field of a scene within a single photograph. This paper explores the fundamental tradeoff between spatial resolution and angular resolution that is inherent to integral photography. ...
    • A Novel Method for Fast and High-Quality Rendering of Hair 

      Xu, Songhua; Lau, Francis C. M.; Jiang, Hao; Pan, Yunhe (The Eurographics Association, 2006)
      This paper proposes a new rendering approach for hair. The model we use incorporates semantics-related information directly in the appearance modeling function which we call a Semantics-Aware Texture Function (SATF). This ...
    • Texture Transfer Using Geometry Correlation 

      Mertens, Tom; Kautz, Jan; Chen, Jiawen; Bekaert, Philippe; Durand, Frédo (The Eurographics Association, 2006)
      Texture variation on real-world objects often correlates with underlying geometric characteristics and creates a visually rich appearance. We present a technique to transfer such geometry-dependent texture variation from ...
    • Real-time Multi-perspective Rendering on Graphics Hardware 

      Hou, Xianyou; Wei, Li-Yi; Shum, Heung-Yeung; Guo, Baining (The Eurographics Association, 2006)
      Multi-perspective rendering has a variety of applications; examples include lens refraction, curved mirror re- flection, caustics, as well depiction and visualization. However, multi-perspective rendering is not yet practical ...
    • Two Stage Importance Sampling for Direct Lighting 

      Cline, David; Egbert, Parris K.; Talbot, Justin F.; Cardon, David L. (The Eurographics Association, 2006)
      We describe an importance sampling method to generate samples based on the product of a BRDF and an environment map or large light source. The method works by creating a hierarchical partition of the light source based on ...
    • Adaptive Visibility-Driven View Cell Construction 

      Mattausch, Oliver; Bittner, Jirí; Wimmer, Michael (The Eurographics Association, 2006)
      We present a new method for the automatic partitioning of view space into a multi-level view cell hierarchy. We use a cost-based model in order to minimize the average rendering time. Unlike previous methods, our model ...
    • Visual Chatter in the Real World 

      Nayar, Shree K.; Krishnan, Gurunandan G. (The Eurographics Association, 2006)
      When a scene is lit by a source of light, the radiance of each point in the scene can be viewed as having two components, namely, direct and global. Recently, an efFIcient separation method has been proposed that uses high ...
    • Handheld Pixels 

      Nordlund, Petri (The Eurographics Association, 2006)
      During this decade, pixels have become mobile. Cell phones, PDAs, handheld gaming consoles and other similar devices start to have color displays by standard and color displays are hungry for high-quality graphics. QVGA ...
    • Silhouette Texture 

      Wu, Hongzhi; Wei, Li-Yi; Wang, Xi; Guo, Baining (The Eurographics Association, 2006)
      Using coarse meshes with textures and/or normal maps to represent detailed meshes often results in poor visual quality along silhouettes. To tackle this problem, we introduce silhouette texture, a new data structure for ...
