      Urban data ranging from images and laser scans to traffic flows are regularly analyzed and modeled leading to better scene understanding. Commonly used computational approaches focus on geometric descriptors, both for ...
    • Pattern-Based Quadrangulation for N-Sided Patches 

      Takayama, Kenshi; Panozzo, Daniele; Sorkine-Hornung, Olga (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We propose an algorithm to quadrangulate an N-sided patch with prescribed numbers of edge subdivisions at its boundary. Our algorithm is guaranteed to succeed for arbitrary valid input, which is proved using a canonical ...
    • SUPER 4PCS: Fast Global Pointcloud Registration via Smart Indexing 

      Mellado, Nicolas; Aiger, Dror; Mitra, Niloy J. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Data acquisition in large-scale scenes regularly involves accumulating information across multiple scans. A common approach is to locally align scan pairs using Iterative Closest Point (ICP) algorithm (or its variants), ...
    • A Variational Taxonomy for Surface Reconstruction from Oriented Points 

      Schroers, Christopher; Setzer, Simon; Weickert, Joachim (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      The problem of reconstructing a watertight surface from a finite set of oriented points has received much attention over the last decades. In this paper, we propose a general higher order framework for surface reconstruction. ...
    • Functional Fluids on Surfaces 

      Azencot, Omri; Weißmann, Steffen; Ovsjanikov, Maks; Wardetzky, Max; Ben-Chen, Mirela (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Fluid simulation plays a key role in various domains of science including computer graphics. While most existing work addresses fluids on bounded Euclidean domains, we consider the problem of simulating the behavior of an ...
    • Pseudo-Spline Subdivision Surfaces 

      Deng, Chongyang; Hormann, Kai (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Pseudo-splines provide a rich family of subdivision schemes with a wide range of choices that meet various demands for balancing the approximation power, the length of the support, and the regularity of the limit functions. ...
