    An Automatic Approach for the Classification of Ancient Clay Statuettes Based on Heads Features Recognition
    (The Eurographics Association, 2019) Scalas, Andreas; Vassallo, Valentina; Mortara, Michela; Spagnuolo, Michela; Hermon, Sorin; Rizvic, Selma and Rodriguez Echavarria, Karina
    In recent years, quantitative approaches based on mathematical theories and ICT tools, known under the terms of digital, computational, and virtual archaeology, are more and more involved in the traditional archaeological research. In this paper, we apply shape analysis techniques to 3D digital replicas of archaeological findings to support their interpretation. In particular, our study focuses on a collection of small terracotta figurines from the ancient sanctuary of Ayia Irini, Cyprus, and it aims at re-analysing the material utilising a quantitative approach. We experiment state of the art techniques (meshSIFT and DBSCAN) to cluster statuettes according to the similarity of their heads, to investigate their production process.

    Shape Analysis Techniques for the Ayia Irini Case Study
    (The Eurographics Association, 2018) Scalas, Andreas; Vassallo, Valentina; Mortara, Michela; Spagnuolo, Michela; Hermon, Sorin; Sablatnig, Robert and Wimmer, Michael
    The typical approach for archaeological analysis is mainly qualitative and, as such, subjective. Even when some measures are reported in the documentation of artefacts, they are often approximate or ambiguous. Conversely, the quantitative approach is based on objective metrics to produce replicable results and, coupled with digital tools, can assist the qualitative analysis in archaological research with no risk of damage. In this paper, we present a geometric-quantitative approach for the analysis of archaeological finds and the preliminary results of an ongoing joint research project of two doctoral students within the frame of the EU GRAVITATE project.
