      In this paper we target the problem of the retrieval of colour patterns over surfaces. We generalize to surface tessellations the well known Local Binary Pattern (LBP) descriptor for images. The key concept of the LBP is ...
    • Microshapes: Efficient Querying of 3D Object Collections based on Local Shape 

      Blokland, Bart Iver van; Theoharis, Theoharis (The Eurographics Association, 2018)
      Content-based querying of 3D object collections has the intrinsic difficulty of creating the query object and previous approaches have concentrated in producing global simplifications such as sketches. In contrast, in this ...

      Recent advances in consumer-grade depth sensors have enable the collection of massive real-world 3D objects. Together with the rise of deep learning, it brings great potential for large-scale 3D object retrieval. In this ...
    • Completion of Cultural Heritage Objects with Rotational Symmetry 

      Sipiran, Ivan (The Eurographics Association, 2018)
      Archaeological artifacts are an important part of our cultural heritage. They help us understand how our ancestors used to live. Unfortunately, many of these objects are badly damaged by the passage of time and need repair. ...
    • Automatic Extraction of Complex 3D Structures Application to the Inner Ear Segmentation from Cone Beam CT Digital Volumes 

      Beguet, Florian; Mari, Jean-Luc; Cresson, Thierry; Schmittbuhl, Matthieu; Guise, Jacques A. de (The Eurographics Association, 2018)
      We present an automatic approach for the retrieval of a complex structure within a 3D digital volume, using a generic deformable surface model. We apply this approach to the inner ear reconstruction of Cone Beam CT(CBCT) ...
