    • Incremental Labelling of Voronoi Vertices for Shape Reconstruction 

      Peethambaran, J.; Parakkat, A.D.; Tagliasacchi, A.; Wang, R.; Muthuganapathy, R. (© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We present an incremental Voronoi vertex labelling algorithm for approximating contours, medial axes and dominant points (high curvature points) from 2D point sets. Though there exist many number of algorithms for ...

    • Selective Padding for Polycube‐Based Hexahedral Meshing 

      Cherchi, G.; Alliez, P.; Scateni, R.; Lyon, M.; Bommes, D. (© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Hexahedral meshes generated from polycube mapping often exhibit a low number of singularities but also poor‐quality elements located near the surface. It is thus necessary to improve the overall mesh quality, in terms of ...

    • A Survey of Simple Geometric Primitives Detection Methods for Captured 3D Data 

      Kaiser, Adrien; Ybanez Zepeda, Jose Alonso; Boubekeur, Tamy (© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
      The amount of captured 3D data is continuously increasing, with the democratization of consumer depth cameras, the development of modern multi‐view stereo capture setups and the rise of single‐view 3D capture based on ...

    • A Variational Approach to Registration with Local Exponential Coordinates 

      Paman, Ashish; Rangarajan, Ramsharan (© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We identify a novel parameterization for the group of finite rotations (SO), consisting of an atlas of exponential maps defined over local tangent planes, for the purpose of computing isometric transformations in registration ...
