      Danelakis, Antonios; Theoharis, Theoharis; Pratikakis, Ioannis (The Eurographics Association, 2014)
      Recently, a lot of research has been dedicated to address the problem of facial expression recognition in dynamic sequences of 3D face scans. On the contrary, no research has been conducted on facial expression retrieval ...

    • Symmetry and Fourier Descriptor: A Hybrid Feature For NURBS based B-Rep Models Retrieval 

      Dang, Quoc Viet; Morin, Geraldine; Mouysset, Sandrine (The Eurographics Association, 2014)
      As the number of models in 3D databases grows, an efficient 3D models indexing mechanism and a similarity measure to ease model retrieval are necessary. In this paper, we present a query-by-model framework for NURBS based ...

    • Similarity of Deforming Meshes Based on Spatio-temporal Segmentation 

      Luo, Guoliang; Cordier, Frederic; Seo, Hyewon (The Eurographics Association, 2014)
      In this study, we investigate a similarity metric for comparing two deforming meshes. While there have been a large body of works on computing the similarity of static shapes, similarity judgments on deforming meshes are ...

    • Coulomb Shapes: Using Electrostatic Forces for Deformation-invariant Shape Representation 

      Boscaini, Davide; Girdziusas, Ramunas; Bronstein, Michael M. (The Eurographics Association, 2014)
      Canonical shape analysis is a popular method in deformable shape matching, trying to bring the shape into a canonical form that undoes its non-rigid deformations, thus reducing the problem of non-rigid matching into a rigid ...

    • Retrieval and Classification on Textured 3D Models 

      Biasotti, S.; Cerri, A.; Abdelrahman, M.; Aono, M.; Hamza, A. Ben; El-Melegy, M.; Farag, A.; Garro, V.; Giachetti, A.; Giorgi, D.; Godil, A.; Li, C.; Liu, Y.-J.; Martono, H. Y.; Sanada, C.; Tatsuma, A.; Velasco-Forero, S.; Xu, C.-X. (The Eurographics Association, 2014)
      This paper reports the results of the SHREC'14 track: Retrieval and classification on textured 3D models, whose goal is to evaluate the performance of retrieval algorithms when models vary either by geometric shape or ...

    • Towards the Extraction of Hierarchical Building Descriptions from 3D Indoor Scans 

      Ochmann, Sebastian; Vock, Richard; Wessel, Raoul; Klein, Reinhard (The Eurographics Association, 2014)
      We present a new method for the hierarchical decomposition of 3D indoor scans and the subsequent generation of an according hierarchical graph-based building descriptor. The hierarchy consists of four basic levels with ...

    • Temporal Ensemble of Shape Functions 

      Brkic, Karla; Aldomà, Aitor; Vincze, Markus; Segvic, Sinisa; Kalafatic, Zoran (The Eurographics Association, 2014)
      This paper proposes novel descriptors that integrate information from multiple views of a 3D object, called Temporal Ensemble of Shape Functions (TESF) descriptors. The TESF descriptors are built by combining per-view ...

    • Shape Retrieval of Non-Rigid 3D Human Models 

      Pickup, D.; Sun, X.; Rosin, P. L.; Martin, R. R.; Cheng, Z.; Lian, Z.; Aono, M.; Hamza, A.
