    • Quantitative Comparison of Hole Filling Methods for 3D Object Search 

      Rojas, Mario A.; Sukno, Federico M.; Waddington, John L.; Whelan, Paul F. (The Eurographics Association, 2014)
      Retrieval of 3D models has become an important issue due to the increase in the number of digitized objects that are available in many different fields. When stored data present defects such as holes, accurate and reliable ...
    • 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 ...
    • 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. Ben; Bronstein, A.; Bronstein, M.; Bu, S.; Castellani, U.; Cheng, S.; Garro, V.; Giachetti, A.; Godil, A.; Han, J.; Johan, H.; Lai, L.; Li, B.; Li, C.; Li, H.; Litman, R.; Liu, X.; Liu, Z.; Lu, Y.; Tatsuma, A.; J.Ye, (The Eurographics Association, 2014)
      We have created a new benchmarking dataset for testing non-rigid 3D shape retrieval algorithms, one that is much more challenging than existing datasets. Our dataset features exclusively human models, in a variety of body ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • TreeSha: 3D Shape Retrieval with a Tree Graph Representation based on the Autodiffusion Function Topology 

      Garro, Valeria; Giachetti, Andrea (The Eurographics Association, 2014)
      In this paper we present a new method for shape description and matching based on a tree representation built upon the scale space analysis of maxima of the Autodiffusion function (ADF). The use of the Heat Kernel based ...
