    • Colorization by Example 

      Irony, Revital; Cohen-Or, Daniel; Lischinski, Dani (The Eurographics Association, 2005)
      We present a new method for colorizing grayscale images by transferring color from a segmented example image. Rather than relying on a series of independent pixel-level decisions, we develop a new strategy that attempts ...

    • A Dual Light Stage 

      Hawkins, Tim; Einarsson, Per; Debevec, Paul (The Eurographics Association, 2005)
      We present a technique for capturing high-resolution 4D reflectance fields using the reciprocity property of light transport. In our technique we place the object inside a diffuse spherical shell and scan a laser across ...

    • Estimation of 3D Faces and Illumination from Single Photographs Using A Bilinear Illumination Model 

      Lee, Jinho; Pfister, Hanspeter; Moghaddam, Baback; Machiraju, Raghu (The Eurographics Association, 2005)
      3D Face modeling is still one of the biggest challenges in computer graphics. In this paper we present a novel framework that acquires the 3D shape, texture, pose and illumination of a face from a single photograph. ...

    • Experimental Analysis of BRDF Models 

      Ngan, Addy; Durand, Frédo; Matusik, Wojciech (The Eurographics Association, 2005)
      The Bidirectional Reflectance Distribution Function (BRDF) describes the appearance of a material by its interaction with light at a surface point. A variety of analytical models have been proposed to represent BRDFs. ...

      Bittner, Jiri; Wonka, Peter; Wimmer, Michael (The Eurographics Association, 2005)
      We present a fast exact from-region visibility algorithm for 2.5D urban scenes. The algorithm uses a subdivision of line space for identifying visibility interactions in a 2D footprint of the scene. Visibility in the ...

    • Geometric Clustering for Line Drawing Simplification 

      Barla, Pascal; Thollot, Joelle; Sillion, François X. (The Eurographics Association, 2005)
      We present a new approach to the simplification of line drawings, in which a smaller set of lines is created to represent the geometry of the original lines. An important feature of our method is that it maintains the ...

    • A Hybrid Monte Carlo Method for Accurate and Efficient Subsurface Scattering 

      Li, Hongsong; Pellacini, Fabio; Torrance, Kenneth E. (The Eurographics Association, 2005)
      Subsurface scattering is a fundamental aspect of surface appearance responsible for the characteristic look of many materials. Monte Carlo path tracing techniques can be employed with high accuracy to simulate the scattering ...

    • Importance Resampling for Global Illumination 

      Talbot, Justin; Cline, David; Egbert, Parris (The Eurographics Association, 2005)
      This paper develops importance resampling into a variance reduction technique for Monte Carlo integration. Importance resampling is a sample generation technique that can be used to generate more equally weighted samples ...

    • Inferring Reflectance Functions from Wavelet Noise 

      Peers, Pieter; Dutré, Philip (The Eurographics Association, 2005)
      This paper presents a novel method for acquiring a wavelet representation of the reflectance field of real objects. Key to our method is the use of wavelet noise illumination to infer a reflectance function for each pixel. ...

    • Interactive System for Dynamic Scene Lighting using Captured Video Environment Maps 

      Havran, Vlastimil; Smyk, Miloslaw; Krawczyk, Grzegorz; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association, 2005)
      We present an interactive system for fully dynamic scene lighting using captured high dynamic range (HDR) video environment maps. The key component of our system is an algorithm for efficient decomposition of HDR video ...

    • A Low Dimensional Framework for Exact Polygon-to-Polygon Occlusion Queries 

      Haumont, Denis; Makinen, Otso; Nirenstein, Shaun (The Eurographics Association, 2005)
      Despite the importance of from-region visibility computation in computer graphics, efficient analytic methods are still lacking in the general 3D case. Recently, different algorithms have appeared that maintain occlusion ...

    • Metropolis Photon Sampling with Optional User Guidance 

      Fan, Shaohua; Chenney, Stephen; Lai, Yu-chi (The Eurographics Association, 2005)
      We present Metropolis Photon Sampling (MPS), a visual importance-driven algorithm for populating photon maps. Photon Mapping and other particle tracing algorithms fail if the photons are poorly distributed. Our approach ...

    • Motion Blur for Textures by Means of Anisotropic Filtering 

      Loviscach, Joern (The Eurographics Association, 2005)
      The anisotropic filtering offered by current graphics hardware can be employed to apply motion blur to textures. The solution proposed here uses a standard texture together with a vertex and a pixel shader acting on a mesh ...

      Tan, Ping; Lin, Stephen; Quan, Long; Guo, Baining; Shum, Heung-Yeung (The Eurographics Association, 2005)
      Physically-based reflectance models typically represent light scattering as a function of surface geometry at the pixel level. With changes in viewing resolution, the geometry imaged within a pixel can undergo significant ...
