  • Mohan, Ankit; Raskar, Ramesh; Tumblin, Jack (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We advocate the use of quickly-adjustable, computer-controlled color spectra in photography, lighting and displays. We present an optical relay system that allows mechanical or electronic color spectrum control and use it ...
  • Mantiuk, Rafal; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    Although several new tone-mapping operators are proposed each year, there is no reliable method to validate their performance or to tell how different they are from one another. In order to analyze and understand the ...
  • Kim, Min H.; Kautz, Jan (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    In this paper we present a new practical camera characterization technique to improve color accuracy in high dynamic range (HDR) imaging. Camera characterization refers to the process of mapping device-dependent signals, ...
  • Clarberg, Petrik; Akenine-Moeller, Tomas (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We present a practical algorithm for sampling the product of environment map lighting and surface reflectance. Our method builds on wavelet-based importance sampling, but has a number of important advantages over previous ...
  • Yuksel, Cem; Keyser, John (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We present a new method for rapidly computing shadows from semi-transparent objects like hair. Our deep opacity maps method extends the concept of opacity shadow maps by using a depth map to obtain a per pixel distribution ...
  • Forest, Vincent; Barthe, Loic; Paulin, Mathias (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    The accurate generation of soft shadows is a particularly computationally intensive task. In order to reduce rendering time, most real-time and offline applications decorrelate the generation of shadows from the computation ...
  • Guennebaud, Gael; Germann, Marcel; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    Algebraic Point Set Surfaces (APSS) define a smooth surface from a set of points using local moving least-squares (MLS) fitting of algebraic spheres. In this paper we first revisit the spherical fitting problem and provide ...
  • Castellani, U.; Cristani, M.; Fantoni, S.; Murino, V. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    This paper proposes new methodology for the detection and matching of salient points over several views of an object. The process is composed by three main phases. In the first step, detection is carried out by adopting a ...
  • Bogomjakov, Alexander; Gotsman, Craig; Isenburg, Martin (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We present a technique for steganography in polygonal meshes. Our method hides a message in the indexed rep-resentation of a mesh by permuting the order in which faces and vertices are stored. The permutation is relative ...
  • Nguyen, Minh Hoai; Lalonde, Jean-Francois; Efros, Alexei A.; De la Torre, Fernando (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    Many categories of objects, such as human faces, can be naturally viewed as a composition of several different layers. For example, a bearded face with glasses can be decomposed into three layers: a layer for glasses, a ...
  • Xuey, Su; Wang, Jiaping; Tong, Xin; Dai, Qionghai; Guo, Baining (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    The appearance manifold [WTL*06] is an efficient approach for modeling and editing time-variant appearance of materials from the BRDF data captured at single time instance. However, this method is difficult to apply in ...
  • Hubball, Daniel; Chen, Min; Grant, Phil W. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    Aging has considerable visual effects on the human face and is difficult to simulate using a universally-applicable global model. In this paper, we focus on the hypothesis that the patterns of age progression (and regression) ...
  • Adams, Andrew; Gelfand, Natasha; Pulli, Kari (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    The viewfinder of a digital camera has traditionally been used for one purpose: to display to the user a preview of what is seen through the camera s lens. High quality cameras are now available on devices such as mobile ...
  • Boettger, Joachim; Preiser, Martin; Balzer, Michael; Deussen, Oliver (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We use the complex logarithm as a transformation for the visualization and navigation of highly complex satellite and aerial imagery. The resulting depictions show details and context with greatly different scales in one ...
  • Ropinski, Timo; Meyer-Spradow, Jennis; Diepenbrock, Stefan; Mensmann, Joerg; Hinrichs, Klaus (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We propose a method for rendering volumetric data sets at interactive frame rates while supporting dynamic ambient occlusion as well as an approximation to color bleeding. In contrast to ambient occlusion approaches for ...
  • Shor, Yael; Lischinski, Dani (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    In this paper we propose a novel method for detecting and removing shadows from a single image thereby obtaining a high-quality shadow-free image. With minimal user assistance, we first identify shadowed and lit areas on ...
  • Jarosz, Wojciech; Zwicker, Matthias; Jensen, Henrik Wann (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We present a new method for efficiently simulating the scattering of light within participating media. Using a theoretical reformulation of volumetric photon mapping, we develop a novel photon gathering technique for ...
  • Gutierrez, Diego; Seron, Francisco J.; Munoz, Adolfo; Anson, Oscar (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    Simulating the in-water ocean light field is a daunting task. Ocean waters are one of the richest participating media, where light interacts not only with water molecules, but with suspended particles and organic matter ...
  • Shesh, Amit; Chen, Baoquan (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    In this paper we present a pipeline for rendering dynamic 2D/3D line drawings efficiently. Our main goal is to create efficient static renditions and coherent animations of line drawings in a setting where lines can be ...
  • Rump, Martin; Mueller, Gero; Sarlette, Ralf; Koch, Dirk; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    State-of-the-art car paint shows not only interesting and subtle angular dependency but also significant spatial variation. Especially in sunlight these variations remain visible even for distances up to a few meters and ...
