    • 3D Shape Matching based on Geodesic Distance Distributions 

      Martinek, Michael; Ferstl, Matthias; Grosso, Roberto (The Eurographics Association, 2012)
      In this work, we present a signature for 3D shapes which is based on the distribution of geodesic distances. Our shape descriptor is invariant with respect to rotation and scaling as well as articulations of the object. ...

    • Optimized Canonical Coordinate Frames for 3D Object Normalization 

      Martinek, Michael; Grosso, Roberto; Greiner, Günther (The Eurographics Association, 2012)
      In this paper, we describe a method to optimize an orthogonal system of axes for 3D objects in order to perform normalization with respect to orientation and scale. An energy function evaluates the quality of a system by ...

    • Resolving Twisted Surfaces within an Iterative Refinement Surface Reconstruction Approach 

      Annuth, Hendrik; Bohn, Christian-A. (The Eurographics Association, 2012)
      We present a method which resolves twisted surface regions within a surface reconstruction approach that uses local refinement operations to iteratively fit a surface into an unorganized point cloud. We show that this local ...

    • SOAR: Stochastic Optimization for Affine global point set Registration 

      Agus, Marco; Gobbetti, Enrico; Villanueva, Alberto Jaspe; Mura, Claudio; Pajarola, Renato (The Eurographics Association, 2014)
      We introduce a stochastic algorithm for pairwise affine registration of partially overlapping 3D point clouds with unknown point correspondences. The algorithm recovers the globally optimal scale, rotation, and translation ...
