      As the number of 3D models is growing on the internet and other domain-specific datasets, the search and retrieval of such models are attracting a lot of attention. A shape descriptor it plays critical roles in the retrieval ...

    • Automatic Shape Expansion with Verification to Improve 3D Retrieval, Classification and Matching 

      Knopp, Jan; Prasad, Mukta; Gool, Luc Van (The Eurographics Association, 2013)
      The goal of this paper is to retrieve 3D object models from a database, that are similar to a single 3D object model, given as a query. The system has no prior models of any object class and is class-generic. The approach ...

    • Compact Vectors of Locally Aggregated Tensors for 3D Shape Retrieval 

      Tabia, Hedi; Picard, David; Laga, Hamid; Gosselin, Philippe-Henri (The Eurographics Association, 2013)
      During the last decade, a significant attention has been paid, by the computer vision and the computer graphics communities, to three dimensional (3D) object retrieval. Shape retrieval methods can be divided into three ...

    • Geometric Histograms of 3D Keypoints for Face Identification with Missing Parts 

      Berretti, Stefano; Werghi, Naoufel; Bimbo, Alberto del; Pala, Pietro (The Eurographics Association, 2013)
      In this work, an original solution to 3D face identification is proposed, which supports recognition also in the case of probes with missing parts. Distinguishing traits of the face are captured by first extracting 3D ...

    • SHREC'13 Track: Retrieval on Textured 3D Models
