      Digital landscape realism often comes from the multitude of details that are hard to model such as fallen leaves, rock piles or entangled fallen branches. In this article, we present a method for augmenting natural scenes ...
    • Flow Curves: an Intuitive Interface for Coherent Scene Deformation 

      Ciccone, Loïc; Guay, Martin; Sumner, Robert W. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Effective composition in visual arts relies on the principle of movement, where the viewer's eye is directed along subjective curves to a center of interest. We call these curves subjective because they may span the edges ...
    • Re-Compositable Panoramic Selfie with Robust Multi-Frame Segmentation and Stitching 

      Li, Kai; Wang, Jue; Liu, Yebin; Xu, Li; Dai, Qionghai (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      It is a challenging task for ordinary users to capture selfies with a good scene composition, given the limited freedom to position the camera. Creative hardware (e.g., selfie sticks) and software (e.g., panoramic selfie ...
    • Skeleton-driven Adaptive Hexahedral Meshing of Tubular Shapes 

      Livesu, Marco; Muntoni, Alessandro; Puppo, Enrico; Scateni, Riccardo (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We propose a novel method for the automatic generation of structured hexahedral meshes of articulated 3D shapes. We recast the complex problem of generating the connectivity of a hexahedral mesh of a general shape into the ...
    • Non-Local Sparse and Low-Rank Regularization for Structure-Preserving Image Smoothing

      This paper presents a new image smoothing method that better preserves prominent structures. Our method is inspired by the recent non-local image processing techniques on the patch grouping and filtering. Overall, it has ...
    • Image Recoloring with Valence-Arousal Emotion Model 

      Kim, Hye-Rin; Kang, Henry; Lee, In-Kwon (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We introduce an affective image recoloring method for changing the overall mood in the image in a numerically measurable way. Given a semantically segmented source image and a target emotion, our system finds reference ...
    • Anisotropic Superpixel Generation Based on Mahalanobis Distance 

      Cai, Yiqi; Guo, Xiaohu (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Superpixels have been widely used as a preprocessing step in various computer vision tasks. Spatial compactness and color homogeneity are the two key factors determining the quality of the superpixel representation. In ...
    • Appearance Harmonization for Single Image Shadow Removal 

      Ma, Li-Qian; Wang, Jue; Shechtman, Eli; Sunkavalli, Kalyan; Hu, Shi-Min (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Shadow removal is a challenging problem and previous approaches often produce de-shadowed regions that are visually inconsistent with the rest of the image. We propose an automatic shadow region harmonization approach that ...
