    • SHREC'09 Track: Generic Shape Retrieval 

      Godil, A.; Dutagaci, H.; Akgül, C.; Axenopoulos, A.; Bustos, B.; Chaouch, M.; Daras, P.; Furuya, T.; Kreft, S.; Lian, Z.; Napoléon, T.; Mademlis, A.; Ohbuchi, R.; Rosin, P. L.; Sankur, B.; Schreck, Tobias; Sun, X.; Tezuka, M.; Verroust-Blondet, A.; Walter, M.; Yemez, Y. (The Eurographics Association, 2009)
      In this paper we present the results of the SHREC'09- Generic Shape Retrieval Contest. The aim of this track was to evaluate the performances of various 3D shape retrieval algorithms on the NIST generic shape benchmark. ...

    • SHREC'09 Track: Querying with Partial Models 

      Dutagaci, H.; Godil, A.; Axenopoulos, A.; Daras, P.; Furuya, T.; Ohbuchi, R. (The Eurographics Association, 2009)
      The objective of the SHREC'09 Querying with Partial Models is to compare the performances of algorithms that accept a range image as the query and retrieve relevant 3D models from a database. The use of a range scan as the ...

    • Template Based Shape Descriptor 

      Rustamov, Raif M. (The Eurographics Association, 2009)
      We introduce a new 3D shape descriptor which maps the surface features onto an arbitrary template surface using mean-value interpolation. A compact numerical shape descriptor is extracted using manifold harmonics on the ...

    • A 3D Shape Benchmark for Retrieval and Automatic Classification of Architectural Data 

      Wessel, Raoul; Blümel, Ina; Klein, Reinhard (The Eurographics Association, 2009)
      When drafting new buildings, architects make intensive use of existing 3D models including building elements, furnishing, and environment elements. These models are either directly included into the draft or serve as a ...

    • Multilevel Relevance Feedback for 3D Shape Retrieval 

      Giorgi, Daniela; Frosini, Patrizio; Spagnuolo, Michela; Falcidieno, Bianca (The Eurographics Association, 2009)
      Relevance feedback techniques are expected to play an important role in 3D search engines, as they help to bridge the semantic gap between the user and the system: similarity is a cognitive process, depending on the observer. ...

    • Retrieval of 3D Articulated Objects Using a Graph-based Representation 

      Agathos, Alexander; Pratikakis, Ioannis; Papadakis, Panagiotis; Perantonis, Stavros; Azariadis, Philip; Sapidis, Nickolas S. (The Eurographics Association, 2009)
      Most of the approaches which address the problem of 3D object retrieval, use global descriptors of the objects which fail to consistently compensate for the intra-class variability of articulated objects. In this paper, a ...

    • Automatic 3D Facial Region Retrieval from Multi-pose Facial Datasets 

      Perakis, Panagiotis; Theoharis, Theoharis; Passalis, Georgios; Kakadiaris, Ioannis A. (The Eurographics Association, 2009)
      The availability of 3D facial datasets is rapidly growing, mainly as a result of medical and biometric applications. These applications often require the retrieval of specific facial areas (such as the nasal region). The ...

    • SkelTre - Fast Skeletonisation for Imperfect Point Cloud Data of Botanic Trees 

      Bucksch, Alexander; Lindenbergh, Roderik C.; Menenti, M. (The Eurographics Association, 2009)
      Terrestrial laser scanners capture 3D geometry as a point cloud. This paper reports on a new algorithm aiming at the skeletonisation of a laser scanner point cloud, representing a botanical tree without leafs. The resulting ...

    • Visual Vocabulary Signature for 3D Object Retrieval and Partial Matching 

      Toldo, Roberto; Castellani, Umberto; Fusiello, Andrea (The Eurographics Association, 2009)
      In this paper a novel object signature is proposed for 3D object retrieval and partial matching. A part-based representation is obtained by partitioning the objects into subparts and by characterizing each segment with ...

    • Partial Matching for Real Textured 3D Objects using Color Cubic Higher-order Local Auto-Correlation Features 

      Kanezaki, Asako; Harada, T.; Kuniyoshi, Y. (The Eurographics Association, 2009)
      In recent years the need for the retrieval of real 3D objects is growing more and more. However, if the 3D models are obtained without the use of special equipment such as engineered environments or multi-camera systems, ...

    • SHREC'09 Track: Structural Shape Retrieval on Watertight Models 

      Hartveldt, J.; Spagnuolo, M.; Axenopoulos, A.; Biasotti, S.; Daras, P.; Dutagaci, H.; Furuya, T.; Godil, A.; Li, X.; Mademlis, A.; Marini, S.; Napoleon, T.; Ohbuchi, R.; Tezuka, M. (The Eurographics Association, 2009)
      The annual SHape REtrieval Contest (SHREC) measures the performance of 3D model retrieval methods for several different types of models and retrieval purposes. In this contest the structural shape retrieval track focuses ...

    • SHREC 2009 - Shape Retrieval Contest 

      Veltkamp, Remco. C.; Haar, Frank B. ter (The Eurographics Association, 2009)
      The general objective of the 3D Shape Retrieval Contest (see http://www.aimatshape.net/event/ SHREC) is to evaluate the effectiveness of 3D-shape retrieval algorithms. After three years of success, the contest is now ...
