    • Path-space Motion Estimation and Decomposition for Robust Animation Filtering 

      Zimmer, Henning; Rousselle, Fabrice; Jakob, Wenzel; Wang, Oliver; Adler, David; Jarosz, Wojciech; Sorkine-Hornung, Olga; Sorkine-Hornung, Alexander (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      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 ...

    • Physically Meaningful Rendering using Tristimulus Colours 

      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. ...

    • Portal-Masked Environment Map Sampling 

      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 ...

    • Probabilistic Connections for Bidirectional Path Tracing 

      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 ...

    • Radiometric Transfer: Example-based Radiometric Linearization of Photographs 

      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 ...

    • Smooth Loops from Unconstrained Video 

      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 ...

    • Stochastic Soft Shadow Mapping 

      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 ...

    • Unifying Color and Texture Transfer for Predictive Appearance Manipulation 

      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 ...

    • Wavelet Point-Based Global Illumination 

      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 ...
