    • Coverage Axis: Inner Point Selection for 3D Shape Skeletonization 

      Dou, Zhiyang; Lin, Cheng; Xu, Rui; Yang, Lei; Xin, Shiqing; Komura, Taku; Wang, Wenping (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      In this paper, we present a simple yet effective formulation called Coverage Axis for 3D shape skeletonization. Inspired by the set cover problem, our key idea is to cover all the surface points using as few inside medial ...

    • Robust Computation of 3D Apollonius Diagrams 

      Wang, Peihui; Yuan, Na; Ma, Yuewen; Xin, Shiqing; He, Ying; Chen, Shuangmin; Xu, Jian; Wang, Wenping (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Apollonius diagrams, also known as additively weighted Voronoi diagrams, are an extension of Voronoi diagrams, where the weighted distance is defined by the Euclidean distance minus the weight. The bisectors of Apollonius ...

    • SRF-Net: Spatial Relationship Feature Network for Tooth Point Cloud Classification 

      Ma, Qian; Wei, Guangshun; Zhou, Yuanfeng; Pan, Xiao; Xin, Shiqing; Wang, Wenping (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      3D scanned point cloud data of teeth is popular used in digital orthodontics. The classification and semantic labelling for point cloud of each tooth is a key and challenging task for planning dental treatment. Utilizing ...
