      Fried, Ohad; Avidan, Shai; Cohen-Or, Daniel (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Many image editing applications rely on the analysis of image patches. In this paper, we present a method to analyze patches by embedding them to a vector space, in which the Euclidean distance reflects patch similarity. ...
    • Performance-Based Biped Control using a Consumer Depth Camera 

      Lee, Yoonsang; Kwon, Taesoo (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a technique for controlling physically simulated characters using user inputs from an off-the-shelf depth camera. Our controller takes a real-time stream of user poses as input, and simulates a stream of target ...
    • A Phase‐Based Approach for Animating Images Using Video Examples 

      Prashnani, Ekta; Noorkami, Maneli; Vaquero, Daniel; Sen, Pradeep (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a novel approach for animating static images that contain objects that move in a subtle, stochastic fashion (e.g. rippling water, swaying trees, or flickering candles). To do this, our algorithm leverages example ...
    • Photometric Stabilization for Fast-forward Videos 

      Zhang, Xuaner; Lee, Joon-Young; Sunkavalli, Kalyan; Wang, Zhaowen (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Videos captured by consumer cameras often exhibit temporal variations in color and tone that are caused by camera autoadjustments like white-balance and exposure. When such videos are sub-sampled to play fast-forward, as ...
    • Point Cloud Denoising via Moving RPCA 

      Mattei, E.; Castrodad, A. (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present an algorithm for the restoration of noisy point cloud data, termed Moving Robust Principal Components Analysis (MRPCA). We model the point cloud as a collection of overlapping two‐dimensional subspaces, and ...
    • Practical Capture and Reproduction of Phosphorescent Appearance 

      Nalbach, Oliver; Seidel, Hans-Peter; Ritschel, Tobias (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper proposes a pipeline to accurately acquire, efficiently reproduce and intuitively manipulate phosphorescent appearance. In contrast to common appearance models, a model of phosphorescence needs to account for ...
    • Practical Path Guiding for Efficient Light-transport Simulation 

      Müller, Thomas; Gross, Markus; Novák, Jan (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a robust, unbiased technique for intelligent light-path construction in path-tracing algorithms. Inspired by existing path-guiding algorithms, our method learns an approximate representation of the scene's ...
    • Predicting Visual Perception of Material Structure in Virtual Environments 

      Filip, J.; Vávra, R.; Havlíček, M.; Krupička, M. (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      One of the most accurate yet still practical representation of material appearance is the Bidirectional Texture Function (BTF). The BTF can be viewed as an extension of Bidirectional Reflectance Distribution Function (BRDF) ...
    • Primal‐Dual Optimization for Fluids
