    • Bilateral Filter Based Compositing for Variable Exposure Photography 

      Raman, Shanmuganathan; Chaudhuri, Subhasis (The Eurographics Association, 2009)
      Compositing a scene from multiple images is of considerable interest to graphics professionals. Typical compositing techniques involve estimation or explicit preparation of matte by an artist. In this article, we address ...
    • Continuous Search and Replace in Vector Graphics 

      Loviscach, Joern (The Eurographics Association, 2009)
      Many types of vector graphics comprise large numbers of almost identical partial shapes such as serifs in typeface design, ornaments in illustrations, and stylistic elements in icon design. As of today, later design changes ...
    • A Cost Metric for Scene-Interior Ray Origins 

      Fabianowski, Bartosz; Fowler, Colin; Dingliana, John (The Eurographics Association, 2009)
      Acceleration structures reducing the number of intersection tests are crucial for high ray tracing performance. The best acceleration structures are currently obtained using the surface area heuristic (SAH) which greedily ...
    • Dent Removal: Geodesic Curve-Based Mesh Fairing 

      Pinskiy, Dmitriy (The Eurographics Association, 2009)
      This paper presents a novel mesh fairing method to remove unwanted geometric artifacts such as dents. The key element of the proposed method is our unique algorithm for the assignment of weights in the discrete Laplacian. ...
    • Depth of Field in Plenoptic Cameras 

      Georgiev, Todor; Lumsdaine, Andrew (The Eurographics Association, 2009)
      Certain new algorithms used by plenoptic cameras require focused microlens images. The range of applicability of these algorithms therefore depends on the depth of field of the relay system comprising the plenoptic camera. ...
    • Does Brief Exposure to a Self-avatar Effect Common Human Behaviors in Immersive Virtual Environments? 

      Streuber, Stephan; Rosa, Stephan de la; Trutoiu, Laura; Bülthoff, Heinrich H.; Mohler, Betty J. (The Eurographics Association, 2009)
      A plausible assumption is that self-avatars increase the realism of immersive virtual environments (VEs), because self-avatars provide the user with a visual representation of his/her own body. Consequently having a ...
    • A Dynamic Caching System for Rendering an Animated Crowd in Real-Time 

      Lister, Wayne; Laycock, Robert G.; Day, Andrew M. (The Eurographics Association, 2009)
      We present a method to accelerate the rendering of large crowds of animated characters. Recent trends have seen matrix-palette skinning become the prevalent approach due to its low memory overhead and fully dynamic geometry. ...
    • Fast Approximation of Multiple Scattering in Inhomogeneous Participating Media 

      Szirmay-Kalos, László; Liktor, Gábor; Umenhoffer, Tamás; Tóth, Balázs (The Eurographics Association, 2009)
      This paper presents a fast approximation for the solution of the radiative transfer equation in inhomogeneous participating media. This scheme traces rays from the point light creating spherical wavefronts. While we march ...
    • Fast Rendering of Particle-Based Fluid by Utilizing Simulation Data 

      Yasuda, Ren; Harada, Takahiro; Kawaguchi, Yoichiro (The Eurographics Association, 2009)
      This paper presents a novel algorithm for efficiently visualizing of particle-based fluid simulation with multiple refractions, especially smoothed particle hydrodynamics(SPH), using data and result of simulation itself. ...
    • A Gaze-Contingent Display Compensating for Scotomata 

      Duchowski, Andrew T.; Eaddy, Tiras D. (The Eurographics Association, 2009)
      A Gaze-Contingent Display (GCD) is developed in GLSL to compensate for scotomata (loss of retinal visual acuity) such as brought on by Age-related Macular Degeneration (AMD). The compensatory GCD introduces a magnification ...
    • Importance Sampling with Floyd-Steinberg Halftoning 

      Szirmay-Kalos, László; Szécsi, László; Penzov, Anton (The Eurographics Association, 2009)
      This paper proposes a deterministic importance sampling algorithm for complex integrands. The idea is based on the recognition that halftoning algorithms are equivalent to importance sampling if the gray-scale image and a ...
    • Improving Interactive Image Segmentation via Appearance Propagation 

      Pan, Wei (The Eurographics Association, 2009)
      We present Propagate-and-Graphcut (PG), a system that improves interactive image segmentation by leveraging the appearance propagation research. Users efforts are minimized, and inaccurate inputs are handled. We show ...
    • Levels of Real-Time Crowd Navigation Behaviour in Urban Environments 

      Haciomeroglu, Murat; Laycock, Robert G.; Day, Andrew M. (The Eurographics Association, 2009)
      Continuously increasing interest in real-time crowd simulations motivates researchers from multiple disciplines to investigate more realistic and efficient simulations. Often real-time crowd simulation systems are developed ...
    • Multisampled Antialiasing of Per-pixel Geometry 

      Schwarz, Michael; Stamminger, Marc (The Eurographics Association, 2009)
      Many algorithms exist which generate per-pixel geometry by selectively discarding fragments generated for a simple bounding geometry. On the other hand, multisampling support has become ubiquitous and is almost free in ...
    • A new Projection Method for Point Set Surfaces 

      Kalbe, Thomas; Fuhrmann, Simon; Uhrig, Stefan; Zeilfelder, Frank; Kuijper, Arjan (The Eurographics Association, 2009)
      A successful approach in triangulating point set surfaces is to apply operations, like a projection operator for advancing front algorithms, directly to Moving-Least Squares (MLS) surfaces. The MLS method naturally handles ...
    • Noise Robust Surface Reconstruction by Combining PU and Graph-cut 

      Nagai, Yukie; Ohtake, Yutaka; Suzuki, Hiromasa (The Eurographics Association, 2009)
      We present a novel method of reconstructing surfaces from 3D scattered points by combining Partition of Unity (PU) and a Graph-cut approach. PU is a local approximation technique, meaning that the surfaces obtained have ...
