    • Semi-sharp Creases on Subdivision Curves and Surfaces 

      Kosinka, Jiri; Sabin, Malcolm A.; Dodgson, Neil A. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We explore a method for generalising Pixar semi-sharp creases from the univariate cubic case to arbitrary degree subdivision curves. Our approach is based on solving simple matrix equations. The resulting schemes allow for ...

    • 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), ...

    • Supervised Learning of Bag-of-features Shape Descriptors Using Sparse Coding 

      Litman, Roee; Bronstein, Alex; Bronstein, Michael; Castellani, Umberto (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present a method for supervised learning of shape descriptors for shape retrieval applications. Many contentbased shape retrieval approaches follow the bag-of-features (BoF) paradigm commonly used in text and image ...

    • Transductive 3D Shape Segmentation using Sparse Reconstruction 

      Xu, Weiwei; Shi, Zhouxu; Xu, Mingliang; Zhou, Kun; Wang, Jingdong; Zhou, Bin; Wang, Jinrong; Yuan, Zhenming (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We propose a transductive shape segmentation algorithm, which can transfer prior segmentation results in database to new shapes without explicitly specification of prior category information. Our method first partitions ...

    • 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. ...

    • What Makes London Work Like London? 

      AlHalawani, Sawsan; Yang, Yong-Liang; Wonka, Peter; Mitra, Niloy J. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      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 ...
