  • Experimental Similarity Assessment for a Collection of Fragmented Artifacts 

    Biasotti, Silvia; Thompson, Elia Moscoso; Spagnuolo, Michela (The Eurographics Association, 2018)
    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 ...
  • Performing Image-like Convolution on Triangular Meshes 

    Tortorici, Claudio; Werghi, Naoufel; Berretti, Stefano (The Eurographics Association, 2018)
    Image convolution with a filtering mask is at the base of several image analysis operations. This is motivated by Mathematical foundations and by the straightforward way the discrete convolution can be computed on a grid-like ...
  • Completion of Cultural Heritage Objects with Rotational Symmetry 

    Sipiran, Ivan (The Eurographics Association, 2018)
    Archaeological artifacts are an important part of our cultural heritage. They help us understand how our ancestors used to live. Unfortunately, many of these objects are badly damaged by the passage of time and need repair. ...
  • Person Re-Identification from Depth Cameras using Skeleton and 3D Face Data 

    Pala, Pietro; Seidenari, Lorenzo; Berretti, Stefano; Bimbo, Alberto Del (The Eurographics Association, 2018)
    In the typical approach, person re-identification is performed using appearance in 2D still images or videos, thus invalidating any application in which a person may change dress across subsequent acquisitions. For example, ...
