    Toward BxDF Display Using Multilayer Diffraction

    We introduce diffractive multilayer BxDF displays to overcome limitations of existing approaches to BxDF display. To this end, we derive forward and inverse methods to generate diffractive patterns that are printed on stacked, high-resolution transparencies and reproduce prescribed BxDFs with unprecedented degrees of freedom.

    Improving Visual Quality of View Transitions in Automultiscopic Displays

    Despite of the widespread use of automultiscopic screens, the image quality is highly affected by the limited angular coverage by the displayed views. We analyze this effect, and reveal artifacts caused by this limitation. We also propose a new idea of modifying the 3D content to minimize these problems.

    Appearance-from-Motion: Recovering Spatially Varying Surface Reflectance under Unknown Lighting

    We present "appearance-from-motion'', a novel method for recovering the spatially varying isotropic surface reflectance from a video of a rotating subject, with known geometry, under unknown natural illumination.

    AppIm: Linear Spaces for Image-based Appearance Editing

    We define non-linear transformations for material parameters such that applying linear operations on them respects their inherent meaning of the parameters. Using these editing spaces, we can apply most imaging operations unmodified in material editing for BRDFs, BSSRDFs and local frames.

    Local Random-Phase Noise for Procedural Texturing

    We present a fast noise model encompassing Gabor noise and noise by Fourier series for interactive procedural texturing. It can not only generate Gaussian patterns from exemplars but also reproduce structured features using a parameter controlling the ratio "structure versus noise".
