    • Fast and Exact (Poisson) Solvers on Symmetric Geometries 

      Kazhdan, Misha (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In computer graphics, numerous geometry processing applications reduce to the solution of a Poisson equation. When considering geometries with symmetry, a natural question to consider is whether and how the symmetry can ...

    • Hierarchical Multiview Rigid Registration 

      Tang, Yizhi; Feng, Jieqing (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Registration is a key step in the 3D reconstruction of real-world objects. In this paper, we propose a hierarchical method for the rigid registration of multiple views. The multiview registration problem is solved via ...

    • Stable Topological Signatures for Points on 3D Shapes 

      Carrière, Mathieu; Oudot, Steve Y.; Ovsjanikov, Maks (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Comparing points on 3D shapes is among the fundamental operations in shape analysis. To facilitate this task, a great number of local point signatures or descriptors have been proposed in the past decades. However, the ...
