  • Probabilistic Visibility Evaluation using Geometry Proxies 

    Billen, Niels; Lagae, Ares; Dutré, Philip (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Evaluating the visibility between two points is a fundamental problem for ray-tracing and path-tracing algorithms. Ideally, visibility computations are organized such that a minimum number of geometric primitives need to ...
  • Hero Wavelength Spectral Sampling 

    Wilkie, Alexander; Nawaz, Sehera; Droske, Marc; Weidlich, Andrea; Hanika, Johannes (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present a spectral rendering technique that offers a compelling set of advantages over existing approaches. The key idea is to propagate energy along paths for a small, constant number of changing wavelengths. The first ...
  • A Physically-Based BSDF for Modeling the Appearance of Paper 

    Papas, Marios; Mesa, Krystle de; Jensen, Henrik Wann (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present a novel appearance model for paper. Based on our appearance measurements for matte and glossy paper, we find that paper exhibits a combination of subsurface scattering, specular reflection, retroreflection, and ...
  • Spectral Ray Differentials 

    Elek, Oskar; Bauszat, Pablo; Ritschel, Tobias; Magnor, Marcus; Seidel, Hans-Peter (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Light refracted by a dispersive interface leads to beautifully colored patterns that can be rendered faithfully with spectral Monte-Carlo methods. Regrettably, results often suffer from chromatic noise or banding, requiring ...
  • Importance Sampling Microfacet-Based BSDFs using the Distribution of Visible Normals 

    Heitz, Eric; d'Eon, Eugene (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present a new approach to microfacet-based BSDF importance sampling. Previously proposed sampling schemes for popular analytic BSDFs typically begin by choosing a microfacet normal at random in a way that is independent ...
  • Error Analysis of Estimators that use Combinations of Stochastic Sampling Strategies for Direct Illumination 

    Subr, Kartic; Nowrouzezahrai, Derek; Jarosz, Wojciech; Kautz, Jan; Mitchell, Kenny (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present a theoretical analysis of error of combinations of Monte Carlo estimators used in image synthesis. Importance sampling and multiple importance sampling are popular variance-reduction strategies. Unfortunately, ...
  • Layered Reconstruction for Defocus and Motion Blur 

    Munkberg, Jacob; Vaidyanathan, Karthik; Hasselgren, Jon; Clarberg, Petrik; Akenine-Möller, Tomas (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Light field reconstruction algorithms can substantially decrease the noise in stochastically rendered images. Recent algorithms for defocus blur alone are both fast and accurate. However, motion blur is a considerably more ...
  • Interactive Parameter Retrieval for Two-Tone Procedural Textures 

    Gieseke, Lena; Koch, Sebastian; Hahn, Jens Uwe; Fuchs, Martin (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    The choice of parameters for procedural textures to achieve a desired appearance poses a challenging problem even for experienced artists. We propose a method to automatically determine such parameters to reproduce the ...
  • User-Assisted Video Stabilization 

    Bai, Jiamin; Agarwala, Aseem; Agrawala, Maneesh; Ramamoorthi, Ravi (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present a user-assisted video stabilization algorithm that is able to stabilize challenging videos when stateof- the-art automatic algorithms fail to generate a satisfactory result. Current methods do not give the user ...
  • Semi-Automated Video Morphing 

    Liao, Jing; Lima, Rodolfo S.; Nehab, Diego; Hoppe, Hugues; Sander, Pedro V. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We explore creating smooth transitions between videos of different scenes. As in traditional image morphing, good spatial correspondence is crucial to prevent ghosting, especially at silhouettes. Video morphing presents ...
  • C-LOD: Context-aware Material Level-of-Detail applied to Mobile Graphics 

    Koulieris, George Alex; Drettakis, George; Cunningham, Douglas; Mania, Katerina (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Attention-based Level-Of-Detail (LOD) managers downgrade the quality of areas that are expected to go unnoticed by an observer to economize on computational resources. The perceptibility of lowered visual fidelity is ...
  • AutoStyle: Automatic Style Transfer from Image Collections to Users' Images 

    Liu, Yiming; Cohen, Michael; Uyttendaele, Matt; Rusinkiewicz, Szymon (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Stylizing photos, to give them an antique or artistic look, has become popular in recent years. The available stylization filters, however, are usually created manually by artists, resulting in a narrow set of choices. ...
  • Bilinear Accelerated Filter Approximation 

    Manson, Josiah; Schaefer, Scott (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Our method approximates exact texture filtering for arbitrary scales and translations of an image while taking into account the performance characteristics of modern GPUs. Our algorithm is fast because it accesses textures ...
  • Vectorising Bitmaps into Semi-Transparent Gradient Layers 

    Richardt, Christian; Lopez-Moreno, Jorge; Bousseau, Adrien; Agrawala, Maneesh; Drettakis, George (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present an interactive approach for decompositing bitmap drawings and studio photographs into opaque and semi-transparent vector layers. Semi-transparent layers are especially challenging to extract, since they require ...
  • Color Me Noisy: Example-based Rendering of Hand-colored Animations with Temporal Noise Control 

    Fi er, Jakub; Lukác, Michal; Jamri ka, Ondrej; Cadik, Martin; Gingold, Yotam; Asente, Paul; Sykora, Daniel (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present an example-based approach to rendering hand-colored animations which delivers visual richness comparable to real artwork while enabling control over the amount of perceived temporal noise. This is important both ...
