      Modeling 3D origami pieces using conventional software is laborious due to the geometric constraints imposed by the complicated layered structure. Targeting origami models used in visual content such as CG illustrations ...
    • Specular Highlight Removal for Real-world Images 

      Fu, Gang; Zhang, Qing; Song, Chengfang; Lin, Qifeng; Xiao, Chunxia (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Removing specular highlight in an image is a fundamental research problem in computer vision and computer graphics. While various methods have been proposed, they typically do not work well for real-world images due to the ...
    • A Stationary SVBRDF Material Modeling Method Based on Discrete Microsurface 

      Zhu, Junqiu; Xu, Yanning; Wang, Lu (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Microfacet theory is commonly used to build reflectance models for surfaces. While traditional microfacet-based models assume that the distribution of a surface's microstructure is continuous, recent studies indicate that ...
    • Style Mixer: Semantic-aware Multi-Style Transfer Network 

      HUANG, Zixuan; ZHANG, Jinghuai; LIAO, Jing (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Recent neural style transfer frameworks have obtained astonishing visual quality and flexibility in Single-style Transfer (SST), but little attention has been paid to Multi-style Transfer (MST) which refers to simultaneously ...
    • Subdivision Schemes for Quadrilateral Meshes with the Least Polar Artifact in Extraordinary Regions 

      Ma, Yue; Ma, Weiyin (The Eurographics Association and John Wiley & Sons Ltd., 2019)

    • Succinct Palette and Color Model Generation and Manipulation Using Hierarchical Representation 

      Jeong, Taehong; Yang, Myunghyun; Shin, Hyun Joon (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We propose a new method to obtain the representative colors and their distributions of an image. Our intuition is that it is possible to derive the global model from the local distributions. Beginning by sampling pure ...
    • Surface Fairing towards Regular Principal Curvature Line Networks 

      Chu, Lei; Bo, Pengbo; Liu, Yang; Wang, Wenping (The Eurographics Association and John Wiley & Sons Ltd., 2019)
