    • Global Selection of Stream Surfaces 

      Esturo, Janick Martinez; Schulze, Maik; Rössl, Christian; Theisel, Holger (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Stream surfaces are well-known and widely-used structures for 3D flow visualization. A single surface can be sufficient to represent important global flow characteristics. Unfortunately, due to the huge space of possible ...

    • Removing the Noise in Monte Carlo Rendering with General Image Denoising Algorithms 

      Kalantari, Nima Khademi; Sen, Pradeep (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Monte Carlo rendering systems can produce important visual effects such as depth of field, motion blur, and area lighting, but the rendered images suffer from objectionable noise at low sampling rates. Although years of ...

    • Stochastic Depth Buffer Compression using Generalized Plane Encoding 

      Andersson, Magnus; Munkberg, Jacob; Akenine-Möller, Tomas (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper, we derive compact representations of the depth function for a triangle undergoing motion or defocus blur. Unlike a static primitive, where the depth function is planar, the depth function is a rational ...

    • Photon Parameterisation for Robust Relaxation Constraints 

      Spencer, Ben; Jones, Mark W. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      This paper presents a novel approach to detecting and preserving fine illumination structure within photon maps. Data derived from each photon's primal trajectory is encoded and used to build a high-dimensional kd-tree. ...

    • Locally Adaptive Products for All-Frequency Relighting 

      Inger, Yaron; Farbman, Zeev; Lischinski, Dani (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Triple product integrals evaluate the shading at a point by factoring the reflection equation into incident illumination, visibility, and BRDF. By densely sampling the space of incident directions, this approach is capable ...

    • Path Space Regularization for Holistic and Robust Light Transport 

      Kaplanyan, Anton S.; Dachsbacher, Carsten (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We propose a simple yet powerful regularization framework for robust light transport simulation. It builds on top of existing unbiased methods and resorts to a consistent estimation using regularization only for paths which ...

    • Accurate Binary Image Selection from Inaccurate User Input 

      Subr, Kartic; Paris, Sylvain; Soler, Cyril; Kautz, Jan (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Selections are central to image editing, e.g., they are the starting point of common operations such as copy-pasting and local edits. Creating them by hand is particularly tedious and scribble-based techniques have been ...

    • DuctTake: Spatiotemporal Video Compositing 

      Rüegg, Jan; Wang, Oliver; Smolic, Aljoscha; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      DuctTake is a system designed to enable practical compositing of multiple takes of a scene into a single video. Current industry solutions are based around object segmentation, a hard problem that requires extensive manual ...

    • Finite Element Image Warping 

      Kaufmann, Peter; Wang, Oliver; Sorkine-Hornung, Alexander; Sorkine-Hornung, Olga; Smolic, Aljoscha; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We introduce a single unifying framework for a wide range of content-aware image warping tasks using a finite element method (FEM). Existing approaches commonly define error terms over vertex finite differences and can be ...

    • Exploring Local Modifications for Constrained Meshes 

      Deng, Bailin; Bouaziz, Sofien; Deuss, Mario; Zhang, Juyong; Schwartzburg, Yuliy; Pauly, Mark (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Mesh editing under constraints is a challenging task with numerous applications in geometric modeling, industrial design, and architectural form finding. Recent methods support constraint-based exploration of meshes with ...

    • Mutable Elastic Models for Sculpting Structured Shapes 

      Milliez, Antoine; Wand, Michael; Cani, Marie-Paule; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper, we propose a new paradigm for free-form shape deformation. Standard deformable models minimize an energy measuring the distance to a single target shape. We propose a new, ''mutable'' elastic model. It ...

    • Circular Arc Snakes and Kinematic Surface Generation 

      Barton, Michael; Shi, Ling; Kilian, Martin; Wallner, Johannes; Pottmann, Helmut (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We discuss the theory, discretization, and numerics of curves which are evolving such that part of their shape, or at least their curvature as a function of arc length, remains unchanged. The discretization of a curve as ...

    • Preface and Table of Contents 

      I. Navazo, P. Poulin (The Eurographics Association and Blackwell Publishing Ltd., 2013)
