      A person's emotions and state of mind are apparent in their face and eyes. As a Latin proverb states: ‘The face is the portrait of the mind; the eyes, its informers’. This presents a significant challenge for Computer ...
    • Specular Lobe‐Aware Filtering and Upsampling for Interactive Indirect Illumination 

      Tokuyoshi, Y. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Although geometry‐aware filtering and upsampling have often been used for interactive or real‐time rendering, they are unsuitable for glossy surfaces because shading results strongly depend on the bidirectional reflectance ...
    • Saliency‐Preserving Slicing Optimization for Effective 3D Printing 

      Wang, Weiming; Chao, Haiyuan; Tong, Jing; Yang, Zhouwang; Tong, Xin; Li, Hang; Liu, Xiuping; Liu, Ligang (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present an adaptive slicing scheme for reducing the manufacturing time for 3D printing systems. Based on a new saliency‐based metric, our method optimizes the thicknesses of slicing layers to save printing time and ...
    • Optimization‐Based Gradient Mesh Colour Transfer

      In vector graphics, gradient meshes represent an image object by one or more regularly connected grids. Every grid point has attributes as the position, colour and gradients of these quantities specified. Editing the ...
    • Forecast Verification and Visualization based on Gaussian Mixture Model Co‐estimation 

      Wang, Y. H.; Fan, C. R.; Zhang, J.; Niu, T.; Zhang, S.; Jiang, J. R. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Precipitation forecast verification is essential to the quality of a forecast. The Gaussian mixture model (GMM) can be used to approximate the precipitation of several rain bands and provide a concise view of the data, ...
    • Non‐Local Image Inpainting Using Low‐Rank Matrix Completion 

      Li, Wei; Zhao, Lei; Lin, Zhijie; Xu, Duanqing; Lu, Dongming (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      .In this paper, we propose a highly accurate inpainting algorithm which reconstructs an image from a fraction of its pixels. Our algorithm is inspired by the recent progress of non‐local image processing techniques following ...
    • Outdoor Human Motion Capture by Simultaneous Optimization of Pose and Camera Parameters 

      Elhayek, A.; Stoll, C.; Kim, K. I.; Theobalt, C. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a method for capturing the skeletal motions of humans using a sparse set of potentially moving cameras in an uncontrolled environment. Our approach is able to track multiple people even in front of cluttered and ...
