    • A 3D Perceptual Metric using Just-Noticeable-Difference 

      Cheng, Irene; Boulanger, Pierre (The Eurographics Association, 2005)
      In multimedia applications, it is essential to distribute resources efficiently among different types of data in order to optimize overall quality. We propose a perceptual metric using Just-Noticeable-Difference (JND) to ...

    • Carving, Painting, and Printing with a Pen Tablet 

      Mizuno, Shinji; Kobayashi, Daigo; Okada, Minoru; Toriwaki, Junichiro; Yamamoto, Shinji (The Eurographics Association, 2005)
      We discuss on an interactive CG system with a pressure sensitive pen tablet. This system is based on the virtual sculpting and printing method which are simulations of real sculpting and woodblock printing. In the sculpting ...

    • Constriction Computation using Surface Curvature 

      Hétroy, F. (The Eurographics Association, 2005)
      This paper provides a curvature-based algorithm to compute locally shortest geodesics on closed triangulated surfaces. These curves, which are called "constrictions", are useful for shape segmentation. The key idea of the ...

    • Differential Photon Mapping - Consistent Augmentation of Photographs with Correction of all Light Paths 

      Grosch, Thorsten (The Eurographics Association, 2005)
      Augmenting images with consistent lighting is possible with differential rendering. This composition technique requires two lighting simulations, one simulation with only real geometry and another one with additional virtual ...

    • Efficient, Physically Plausible Finite Elements 

      Nesme, Matthieu; Payan, Yohan; Faure, François (The Eurographics Association, 2005)
      This paper discusses FEM-based simulations of soft bodies in terms of speed and robustness. To be physically plausible, three fundamental laws must be respected: rotational invariance, Newton's law and Euler's law. We show ...

    • Estimating Mobile Memory Requirements and Rendering Time for Remote Execution of the Graphics Pipeline 

      Banerjee, Kutty; Wu, Fan; Agu, Emmanuel (The Eurographics Association, 2005)
      Mobile devices have limited processing power, memory and battery power. Remote execution, wherein part or entire graphics pipeline is offloaded to a powerful surrogate server, is an attractive solution for low end mobile ...

    • Facial Motion Cloning Using Global Shape Deformation 

      Fratarcangeli, Marco; Schaerf, Marco (The Eurographics Association, 2005)
      We present a novel Facial Motion Cloning method relying on the combination of the radial basis functions (RBF) based scattered data interpolation with the encoding capabilities of the MPEG-4 Facial and Body Animation (FBA) ...

    • Fast and Controllable 3D Modelling From Silhouettes 

      Prasad, Mukta; Fitzgibbon, Andrew; Zisserman, Andrew (The Eurographics Association, 2005)
      We show how a 3D model of a complex curved object can be easily extracted from a single 2D image. A userdefined silhouette is the key input; and we show that finding the smoothest 3D surface which projects exactly to this ...

    • Fast Body-Cloth simulation with moving humanoids 

      Rodriguez-Navarro, Javier; Sainz, Miguel; Susin, Antonio (The Eurographics Association, 2005)
      In this paper we present a very fast method for body-cloth animation. The usual bottle-neck in cloth simulation performance is collision detection, which becomes more difficult to solve when a complex geometry, like a human ...

    • Image Reconstruction Invariant to Relighting 

      Georgiev, Todor (The Eurographics Association, 2005)
      This paper describes an improvement to the Poisson image editing method for seamless cloning. Our approach is based on minimizing an energy expression invariant to relighting. The improved method reconstructs seamlessly ...

    • Improving the Experience of Scenes with a Large Field of View using Shift Lens Perspective 

      Hoeben, Aldo; Stappers, Pieter Jan (The Eurographics Association, 2005)
      In interactive computer graphics such as games and interactive panoramic photos, users are often presented a view with a larger field of view than would correspond to the distance to and size of the screen on which the ...

    • Interactive Manipulation Of Projections With a Curved Perspective 

      Sudarsanam, Nisha; Grimm, Cindy M; Singh, Karan (The Eurographics Association, 2005)
      The concept of curved perspective has been used by artists such as M.C. Escher in order effectively convey a sense of three dimensional space while being restricted to a two dimensional canvas. We present an interactive ...

    • Leaf Cluster Impostors for Tree Rendering with Parallax 

      Garcia, Ismael; Sbert, Mateu; Szirmay-Kalos, László (The Eurographics Association, 2005)
      This paper presents a simple method to render complex trees on high frame rates while maintaining parallax effects. Based on the recognition that a planar impostor is accurate if the represented polygon is in its plane, ...

    • Model-driven Virtual Mezzotint Techniques 

      Tasaki, Daisuke; Mizuno, Shinji; Okada, Minoru (The Eurographics Association, 2005)
      Mezzotint is a traditional printing technique that is categorized into copperplate printing where an entire plate surface is roughened by some steel tools. In this paper the authors propose a method to realize two mezzotint ...

    • Path Planning for Crowds: From Shared Goals to Individual Behaviors 

      Pettre, Julien; Thalmann, Daniel (The Eurographics Association, 2005)
      This paper presents a novel approach for path planning in the context of crowds animation. The solution produces several paths joining each user-defined pair of locations in the environment. Pairs are possible initial/goal ...

    • Perception-Based Rendering: Eyes Wide Bleached 

      Gutierrez, Diego; Anson, Oscar; Munoz, Adolfo; Seron, Francisco J. (The Eurographics Association, 2005)
      Perception issues are a key factor in rendering Vision-Realistic images. This paper develops a novel spectral sensitive model of the Human Visual System (HVS) in order to simulate the bleaching effect in retinal photopigments. ...
