    • ScribbleBoost: Adding Classification to Edge-Aware Interpolation of Local Image and Video Adjustments 

      Li, Y.; Adelson, E.; Agarwala, A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      One of the most common tasks in image and video editing is the local adjustment of various properties (e.g., saturation or brightness) of regions within an image or video. Edge-aware interpolation of user-drawn scribbles ...

    • Combining Confocal Imaging and Descattering 

      Fuchs, Christian; Heinz, Michael; Levoy, Marc; Seidel, Hans-Peter; Lensch, Hendrik P. A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In translucent objects, light paths are affected by multiple scattering, which is polluting any observation. Confocal imaging reduces the influence of such global illumination effects by carefully focusing illumination and ...

    • ReduceM: Interactive and Memory Efficient Ray Tracing of Large Models 

      Lauterbach, Christian; Yoon, Sung-eui; Tang, Ming; Manocha, Dinesh (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a novel representation and algorithm, ReduceM, for memory efficient ray tracing of large scenes. ReduceM exploits the connectivity between triangles in a mesh and decomposes the model into triangle strips. We ...

    • Accelerating Ray Tracing using Constrained Tetrahedralizations 

      Lagae, Ares; Dutre, Philip (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we introduce the constrained tetrahedralization as a new acceleration structure for ray tracing. A constrained tetrahedralization of a scene is a tetrahedralization that respects the faces of the scene geometry. ...

    • Fast Soft Self-Shadowing on Dynamic Height Fields 

      Snydre, John; Nowrouzezahrai, Derek (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a new, real-time method for rendering soft shadows from large light sources or lighting environments on dynamic height fields. The method first computes a horizon map for a set of azimuthal directions. To reduce ...

    • Sample Based Visibility for Soft Shadows using Alias-free Shadow Maps 

      Sintorn, Erik; Eisemann, Elmar; Assarsson, Ulf (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper introduces an accurate real-time soft shadow algorithm that uses sample based visibility. Initially, we present a GPU-based alias-free hard shadow map algorithm that typically requires only a single render pass ...

    • Free Form Incident Light Fields 

      Unger, J.; Gustavson, S.; Larsson, P.; Ynnerman, A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents methods for photo-realistic rendering using strongly spatially variant illumination captured from real scenes. The illumination is captured along arbitrary paths in space using a high dynamic range, ...
