      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 ...
    • 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 ...
    • 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 ...
    • An Image Degradation Model for Depth-augmented Image Editing 

      Hennessey, James W.; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Images remain the most popular medium to capture our surroundings. Although significant advances have been made in developing image editing tools, the key challenge is to intelligently account for missing depth information. ...
    • Dynamic SfM: Detecting Scene Changes from Image Pairs 

      Wang, Tuanfeng Y.; Kohli, Pushmeet; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Detecting changes in scenes is important in many scene understanding tasks. In this paper, we pursue this goal simply from a pair of image recordings. Specifically, our goal is to infer what the objects are, how they are ...
    • Quaternion Julia Set Shape Optimization 

      Kim, Theodore (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present the first 3D algorithm capable of answering the question: what would a Mandelbrot-like set in the shape of a bunny look like? More concretely, can we find an iterated quaternion rational map whose potential field ...
    • Robust Articulated-ICP for Real-Time Hand Tracking 

      Tagliasacchi, Andrea; Schröder, Matthias; Tkach, Anastasia; Bouaziz, Sofien; Botsch, Mario; Pauly, Mark (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a robust method for capturing articulated hand motions in realtime using a single depth camera. Our system is based on a realtime registration process that accurately reconstructs hand poses by fitting a 3D ...
    • Reforming Shapes for Material-aware Fabrication 

      Yang, Yong-Liang; Wang, Jun; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      As humans, we regularly associate shape of an object with its built material. In the context of geometric modeling, however, this inter-relation between form and material is rarely explored. In this work, we propose a novel ...
    • Analysis and Synthesis of 3D Shape Families via Deep-learned Generative Models of Surfaces 

      Huang, Haibin; Kalogerakis, Evangelos; Marlin, Benjamin (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a method for joint analysis and synthesis of geometrically diverse 3D shape families. Our method first learns part-based templates such that an optimal set of fuzzy point and part correspondences is computed ...
    • Example Based Repetitive Structure Synthesis 

      Roveri, Riccardo; Öztireli, A. Cengiz; Martin, Sebastian; Solenthaler, Barbara; Gross, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present an example based geometry synthesis approach for generating general repetitive structures. Our model is based on a meshless representation, unifying and extending previous synthesis methods. Structures in the ...
    • Sparse Non-rigid Registration of 3D Shapes 

      Yang, Jingyu; Li, Ke; Li, Kun; Lai, Yu-Kun (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Non-rigid registration of 3D shapes is an essential task of increasing importance as commodity depth sensors become more widely available for scanning dynamic scenes. Non-rigid registration is much more challenging than ...
    • LeSSS: Learned Shared Semantic Spaces for Relating Multi-Modal Representations of 3D Shapes 

      Herzog, Robert; Mewes, Daniel; Wand, Michael; Guibas, Leonidas; Seidel, Hans-Peter (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In this paper, we propose a new method for structuring multi-modal representations of shapes according to semantic relations. We learn a metric that links semantically similar objects represented in different modalities. ...
    • Continuous Matching via Vector Field Flow 

      Corman, Etienne; Ovsjanikov, Maks; Chambolle, Antonin (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a new method for non-rigid shape matching designed to enforce continuity of the resulting correspondence. Our method is based on the recently proposed functional map representation, which allows efficient ...
    • Tight Relaxation of Quadratic Matching 

      Kezurer, Itay; Kovalsky, Shahar Z.; Basri, Ronen; Lipman, Yaron (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Establishing point correspondences between shapes is extremely challenging as it involves both finding sets of semantically persistent feature points, as well as their combinatorial matching.We focus on the latter and ...
    • Texture Mapping Real-World Objects with Hydrographics 

      Panozzo, Daniele; Diamanti, Olga; Paris, Sylvain; Tarini, Marco; Sorkine, Evgeni; Sorkine-Hornung, Olga (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In the digital world, assigning arbitrary colors to an object is a simple operation thanks to texture mapping. However, in the real world, the same basic function of applying colors onto an object is far from trivial. One ...
    • A One-dimensional Homologically Persistent Skeleton of an Unstructured Point Cloud in any Metric Space 

      Kurlin, Vitaliy (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Real data are often given as a noisy unstructured point cloud, which is hard to visualize. The important problem is to represent topological structures hidden in a cloud by using skeletons with cycles. All past skeletonization ...
