    • Extracting Microfacet-based BRDF Parameters from Arbitrary Materials with Power Iterations 

      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 ...

    • Modeling Luminance Perception at Absolute Threshold 

      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 ...

    • Motion Aware Exposure Bracketing for HDR Video 

      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 ...

    • 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 ...
