  • Reich, Andreas; Günther, Tobias; Grosch, Thorsten (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    Progressive light transport simulations aspire a physically-based, consistent rendering to obtain visually appealing illumination effects, depth and realism. Thereby, the handling of large scenes is a difficult problem, ...
  • Kellnhofer, Petr; Ritschel, Tobias; Myszkowski, Karol; Eisemann, Elmar; Seidel, Hans-Peter (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    When human luminance perception operates close to its absolute threshold, i. e., the lowest perceivable absolute values, appearance changes substantially compared to common photopic or scotopic vision. In particular, most ...
  • Wang, Beibei; Meng, Xiangxu; Boubekeur, Tamy (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    Point-Based Global Illumination (PBGI) is a popular rendering method in special effects and motion picture productions. This algorithm provides a diffuse global illumination solution by caching radiance in a mesh-less ...

    Renderings of animation sequences with physics-based Monte Carlo light transport simulations are exceedingly costly to generate frame-by-frame, yet much of this computation is highly redundant due to the strong coherence ...
  • Gryaditskaya, Yulia; Pouli, Tania; Reinhard, Erik; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    Mobile phones and tablets are rapidly gaining significance as omnipresent image and video capture devices. In this context we present an algorithm that allows such devices to capture high dynamic range (HDR) video. The ...
  • Li, Han; Peers, Pieter (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    We present an example-based approach for radiometrically linearizing photographs that takes as input a radiometrically linear exemplar image and a target regular uncalibrated image of the same scene, possibly from a different ...
  • Sevilla-Lara, Laura; Wulff, Jonas; Sunkavalli, Kalyan; Shechtman, Eli (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    Converting unconstrained video sequences into videos that loop seamlessly is an extremely challenging problem. In this work, we take the first steps towards automating this process by focusing on an important subclass of ...
  • Hanika, Johannes; Droske, Marc; Fascione, Luca (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    We present manifold next event estimation (MNEE), a specialised technique for Monte Carlo light transport simulation to render refractive caustics by connecting surfaces to light sources (next event estimation) across ...
  • Popov, Stefan; Ramamoorthi, Ravi; Durand, Fredo; Drettakis, George (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    Bidirectional path tracing (BDPT) with Multiple Importance Sampling is one of the most versatile unbiased rendering algorithms today. BDPT repeatedly generates sub-paths from the eye and the lights, which are connected for ...
  • Hanika, Johannes; Kaplanyan, Anton; Dachsbacher, Carsten (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    In this paper, we present improvements to half vector space light transport (HSLT) [KHD14], which make this approach more practical, robust for difficult input geometry, and faster. Our first contribution is the computation ...
  • Okura, Fumio; Vanhoey, Kenneth; Bousseau, Adrien; Efros, Alexei A.; Drettakis, George (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    Recent color transfer methods use local information to learn the transformation from a source to an exemplar image, and then transfer this appearance change to a target image. These solutions achieve very successful results ...
  • Günther, Tobias; Grosch, Thorsten (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    Even though much research was dedicated to the acceleration of consistent, progressive light transport simulations, the computation of fully converged images is still very time-consuming. This is problematic, as for the ...
  • Meng, Johannes; Simon, Florian; Hanika, Johannes; Dachsbacher, Carsten (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    In photorealistic image synthesis the radiative transfer equation is often not solved by simulating every wavelength of light, but instead by computing tristimulus transport, for instance using sRGB primaries as a basis. ...
  • Dupuy, Jonathan; Heitz, Eric; Iehl, Jean-Claude; Poulin, Pierre; Ostromoukhov, Victor (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    We introduce a novel fitting procedure that takes as input an arbitrary material, possibly anisotropic, and automatically converts it to a microfacet BRDF. Our algorithm is based on the property that the distribution of ...
  • Bitterli, Benedikt; Novák, Jan; Jarosz, Wojciech (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    We present a technique to e ciently importance sample distant, all-frequency illumination in indoor scenes. Standard environment sampling is ine cient in such cases since the distant lighting is typically only visible ...
  • Liktor, Gabor; Spassov, Stanislav; Mückl, Gregor; Dachsbacher, Carsten (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    In this paper, we extend the concept of pre-filtered shadow mapping to stochastic rasterization, enabling real-time rendering of soft shadows from planar area lights. Most existing soft shadow mapping methods lose important ...
