    • Fast Ray Tracing of Arbitrary Implicit Surfaces with Interval and Affine Arithmetic 

      Knoll, A.; Hijazi, Y.; Kensler, A.; Schott, M.; Hansen, C.; Hagen, H. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Existing techniques for rendering arbitrary-form implicit surfaces are limited, either in performance, correctness or flexibility. Ray tracing algorithms employing interval arithmetic (IA) or affine arithmetic (AA) for ...

    • A Psychophysical Evaluation of Inverse Tone Mapping Techniques 

      Banterle, Francesco; Ledda, Patrick; Debattista, Kurt; Bloj, Marina; Artusi, Alessandro; Chalmers, Alan (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In recent years inverse tone mapping techniques have been proposed for enhancing low-dynamic range (LDR) content for a high-dynamic range (HDR) experience on HDR displays, and for image based lighting. In this paper, we ...

    • Compression of Human Motion Capture Data Using Motion Pattern Indexing 

      Gu, Qin; Peng, Jingliang; Deng, Zhigang (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In this work, a novel scheme is proposed to compress human motion capture data based on hierarchical structure construction and motion pattern indexing. For a given sequence of 3D motion capture data of human body, the 3D ...

    • Efficient Geometry Compression for GPU-based Decoding in Realtime Terrain Rendering 

      Dick, Christian; Schneider, Jens; Westermann, Ruediger (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We present a geometry compression scheme for restricted quadtree meshes and use this scheme for the compression of adaptively triangulated digital elevation models (DEMs). A compression factor of 8-9 is achieved by employing ...

    • BTF-CIELab: A Perceptual Difference Measure for Quality Assessment and Compression of BTFs 

      Guthe, Michael; Mueller, Gero; Schneider, Martin; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Driven by the advances in lossy compression of bidirectional texture functions (BTFs), there is a growing need for reliable methods to numerically measure the visual quality of the various compressed representations. Based ...

    • Tangential Distance Fields for Mesh Silhouette Problems 

      Olson, M.; Zhang, H. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We consider a tangent-space representation of surfaces that maps each point on a surface to the tangent plane of the surface at that point. Such representations are known to facilitate the solution of several visibility ...

    • Editorial 

      Scopigno, Roberto; Groeller, Eduard (The Eurographics Association and Blackwell Publishing Ltd, 2009)

    • Resolution Independent NPR-Style 3D Line Textures 

      Potter, Kristin; Gooch, Amy; Gooch, Bruce; Willemsen, Peter; Kniss, Joe; Riesenfeld, Richard; Shirley, Peter (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      This work introduces a technique for interactive walk-throughs of non-photorealistically rendered (NPR) scenes using three-dimensional (3D) line primitives to define architectural features of the model, as well as indicate ...

    • Partial 3D Shape Retrieval by Reeb Pattern Unfolding 

      Tierny, Julien; Vandeborre, Jean-Philippe; Daoudi, Mohamed (The Eurographics Association and Blackwell Publishing Ltd, 2009)

    • Out-of-Core and Dynamic Programming for Data Distribution on a Volume Visualization Cluster 

      Frank, S.; Kaufman, A. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Ray directed volume-rendering algorithms are well suited for parallel implementation in a distributed cluster environment. For distributed ray casting, the scene must be partitioned between nodes for good load balancing, ...

    • Shape Context Preserving Deformation of 2D Anatomical Illustrations 

      Chen, Wei; Liang, Xiao; Maciejewski, Ross; Ebert, David S. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In this paper, we present a novel two-dimensional (2D) shape context preserving image manipulation approach which constructs and manipulates a 2D mesh with a new differential mesh editing algorithm. We introduce a novel ...

    • Exposure Fusion: A Simple and Practical Alternative to High Dynamic Range Photography 

      Mertens, T.; Kautz, J.; Van Reeth, F. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We propose a technique for fusing a bracketed exposure sequence into a high quality image, without converting to High dynamic range (HDR) first. Skipping the physically based HDR assembly step simplifies the acquisition ...

    • Visual-Quality Optimizing Super Resolution 

      Liu, F.; Wang, J.; Zhu, S.; Gleicher, M.; Gong, Y. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In this paper, we propose a robust image super-resolution (SR) algorithm that aims to maximize the overall visual quality of SR results. We consider a good SR algorithm to be fidelity preserving, image detail enhancing and ...

    • A Comparison of Tabular PDF Inversion Methods 

      Cline, D.; Razdan, A.; Wonka, P. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      The most common form of tabular inversion used in computer graphics is to compute the cumulative distribution table of a probability distribution (PDF) and then search within it to transform points, using an O(logA n) ...
