    • Shape Segmentation and Matching from Noisy Point Clouds 

      Dey, Tamal K.; Giesen, Joachim; Goswami, Samrat (The Eurographics Association, 2004)
      We present the implementation results of a shape segmentation technique and an associated shape matching method whose input is a point sample from the shape. The sample is allowed to be noisy in the sense that they may ...

    • Stratified Point Sampling of 3D Models 

      Nehab, Diego; Shilane, Philip (The Eurographics Association, 2004)
      Point sampling is an important intermediate step for a variety of computer graphics applications, and specialized sampling strategies have been developed to satisfy the requirements of each problem. In this article, we ...

    • Topological estimation using witness complexes 

      Silva, Vin de; Carlsson, Gunnar (The Eurographics Association, 2004)
      This paper tackles the problem of computing topological invariants of geometric objects in a robust manner, using only point cloud data sampled from the object. It is now widely recognised that this kind of topological ...

    • Uncertainty and Variability in Point Cloud Surface Data 

      Pauly, Mark; Mitra, Niloy J.; Guibas, Leonidas J. (The Eurographics Association, 2004)
      We present a framework for analyzing shape uncertainty and variability in point-sampled geometry. Our representation is mainly targeted towards discrete surface data stemming from 3D acquisition devices, where a finite ...
