    • InK‐Compact: In‐Kernel Stream Compaction and Its Application to Multi‐Kernel Data Visualization on General‐Purpose GPUs 

      Hughes, D. M.; Lim, I. S.; Jones, M. W.; Knoll, A.; Spencer, B. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Stream compaction is an important parallel computing primitive that produces a reduced (compacted) output stream consisting of only valid elements from an input stream containing both invalid and valid elements. Computing ...

    • Real‐Time Defocus Rendering With Level of Detail and Sub‐Sample Blur 

      Jeong, Yuna; Kim, Kangtae; Lee, Sungkil (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      This paper presents a GPU‐based rendering algorithm for real‐time defocus blur effects, which significantly improves the accumulation buffering. The algorithm combines three distinctive techniques: (1) adaptive discrete ...

    • Enhancing Bayesian Estimators for Removing Camera Shake 

      Wang, C.; Yue, Y.; Dong, F.; Tao, Y.; Ma, X.; Clapworthy, G.; Ye, X. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      The aim of removing camera shake is to estimate a sharp version x from a shaken image y when the blur kernel k is unknown. Recent research on this topic evolved through two paradigms called MAP(k) and MAP(x,k). MAP(k) only ...

    • Robust Fitting on Poorly Sampled Data for Surface Light Field Rendering and Image Relighting 

      Vanhoey, K.; Sauvage, B.; Génevaux, O.; Larue, F.; Dischler, J.‐M. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Two‐dimensional (2D) parametric colour functions are widely used in Image‐Based Rendering and Image Relighting. They make it possible to express the colour of a point depending on a continuous directional parameter: the ...

    • Curve Style Analysis in a Set of Shapes 

      Li, H.; Zhang, H.; Wang, Y.; Cao, J.; Shamir, A.; Cohen‐Or, D. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      The word ‘style’ can be interpreted in so many different ways in so many different contexts. To provide a general analysis and understanding of styles is a highly challenging problem. We pose the open question ‘how to ...

    • Efficient Non‐linear Optimization via Multi‐scale Gradient Filtering 

      Martin, Tobias; Joshi, Pushkar; Bergou, Miklós; Carr, Nathan (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present a method for accelerating the convergence of continuous non‐linear shape optimization algorithms. We start with a general method for constructing gradient vector fields on a manifold, and we analyse this method ...

    • Quad‐Mesh Generation and Processing: A Survey 

      Bommes, David; Lévy, Bruno; Pietroni, Nico; Puppo, Enrico; Silva, Claudio; Tarini, Marco; Zorin, Denis (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Triangle meshes have been nearly ubiquitous in computer graphics, and a large body of data structures and geometry processing algorithms based on them has been developed in the literature. At the same time, quadrilateral ...

    • Full Wave Modelling of Light Propagation and Reflection 

      Musbach, A.; Meyer, G. W.; Reitich, F.; Oh, S. H. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      The propagation and reflection of electromagnetic waves in a three‐dimensional environment is simulated, and realistic images are produced using the resulting light distributions and reflectance functions. A finite difference ...

    • Visualization Mosaics for Multivariate Visual Exploration 

      MacNeil, S.; Elmqvist, N. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present a new model for creating composite visualizations of multidimensional data sets using simple visual representations such as point charts, scatterplots and parallel coordinates as components. Each visual ...

    • Symmetry in 3D Geometry: Extraction and Applications 

      Mitra, Niloy J.; Pauly, Mark; Wand, Michael; Ceylan, Duygu (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      The concept of symmetry has received significant attention in computer graphics and computer vision research in recent years. Numerous methods have been proposed to find, extract, encode and exploit geometric symmetries ...

    • Issue Information 

      Holly Rushmeier and Oliver Deussen (The Eurographics Association and Blackwell Publishing Ltd., 2013)

    • Watertight Scenes from Urban LiDAR and Planar Surfaces 

      Kreveld, Marc van; Lankveld, Thijs van; Veltkamp, Remco C. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      The demand for large geometric models is increasing, especially of urban environments. This has resulted in production of massive point cloud data from images or LiDAR. Visualization and further processing generally require ...

    • Noise-Adaptive Shape Reconstruction from Raw Point Sets 

      Giraudot, Simon; Cohen-Steiner, David; Alliez, Pierre (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We propose a noise-adaptive shape reconstruction method specialized to smooth, closed shapes. Our algorithm takes as input a defect-laden point set with variable noise and outliers, and comprises three main steps. First, ...

    • Consolidation of Low-quality Point Clouds from Outdoor Scenes 

      Wang, Jun; Xu, Kai; Liu, Ligang; Cao, Junjie; Liu, Shengjun; Yu, Zeyun; Gu, Xianfeng David (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      The emergence of laser/LiDAR sensors, reliable multi-view stereo techniques and more recently consumer depth cameras have brought point clouds to the forefront as a data format useful for a number of applications. ...

    • Dirichlet Energy for Analysis and Synthesis of Soft Maps 

      Solomon, Justin; Guibas, Leonidas; Butscher, Adrian (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Soft maps taking points on one surface to probability distributions on another are attractive for representing surface mappings in the presence of symmetry, ambiguity, and combinatorial complexity. Few techniques, however, ...

    • Dynamic Maps for Exploring and Browsing Shapes 

      Kleiman, Yanir; Fish, Noa; Lanir, Joel; Cohen-Or, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2013)
