    Experimental Similarity Assessment for a Collection of Fragmented Artifacts
    (The Eurographics Association, 2018) Biasotti, Silvia; Thompson, Elia Moscoso; Spagnuolo, Michela; Telea, Alex and Theoharis, Theoharis and Veltkamp, Remco
    In the Visual Heritage domain, search engines are expected to support archaeologists and curators to address cross-correlation and searching across multiple collections. Archaeological excavations return artifacts that often are damaged with parts that are fragmented in more pieces or totally missing. The notion of similarity among fragments cannot simply base on the geometric shape but style, material, color, decorations, etc. are all important factors that concur to this concept. In this work, we discuss to which extent the existing techniques for 3D similarity matching are able to approach fragment similarity, what is missing and what is necessary to be further developed.

    Recognition of Geometric Patterns Over 3D Models
    (The Eurographics Association, 2018) Biasotti, S.; Moscoso Thompson, E.; Barthe, L.; Berretti, S.; Giachetti, A.; Lejemble, T.; Mellado, N.; Moustakas, K.; Manolas, Iason; Dimou, Dimitrios; Tortorici, C.; Velasco-Forero, S.; Werghi, N.; Polig, M.; Sorrentino, G.; Hermon, S.; Telea, Alex and Theoharis, Theoharis and Veltkamp, Remco
    This track of the SHREC 2018 originally aimed at recognizing relief patterns over a set of triangle meshes from laser scan acquisitions of archaeological fragments. This track approaches a lively and very challenging problem that remains open after the end of the track. In this report we discuss the challenges to face to successfully address geometric pattern recognition over surfaces; how the existing techniques can go further in this direction, what is currently missing and what is necessary to be further developed.
