  • Pintus, Ruggero; Yang, Ying; Rushmeier, Holly; Gobbetti, Enrico (2017)
    Massive digital acquisition and preservation of deteriorating historical and artistic documents is of particular importance due to their value and fragile condition. The study and browsing of such digital libraries is ...
  • Pintus, Ruggero; Giachetti, Andrea; Pintore, Giovanni; Gobbetti, Enrico (British Machine Vision Association, 2017-09)
    The generation of a basic matte model is at the core of many multi-light reflectance processing approaches, such as Photometric Stereo or Reflectance Transformation Imaging. To recover information on objects’ shape and ...
  • Giachetti, Andrea; Ciortan, Irina; Daffara, Claudia; Rizzon, Federico; Pintus, Ruggero; Gobbetti, Enrico (the Eurographics Association, 2017-09)
    We propose a novel multi-spectral reflectance transformation imaging (MS-RTI) framework for the acquisition and direct analysis of the reflectance behavior of heterogeneous artworks. Starting from free-form acquisitions, ...
  • Giachetti, Andrea; Ciortan, Irina; Daffara, Claudia; Marchioro, Giacomo; Pintus, Ruggero; Gobbetti, Enrico (Elsevier, 2017-05-30)
    We propose a novel pipeline and related software tools for processing the multi-light image collections (MLICs) acquired in different application contexts to obtain shape and appearance information of captured surfaces, ...
  • Pintus, Ruggero; Ciortan, Irina; Giachetti, Andrea; Gobbetti, Enrico (the Eurographics Association, 2016-10)
    We present an automated light calibration pipeline for free-form acquisition of shape and reflectance of objects using common off-the-shelf illuminators, such as LED lights, that can be placed arbitrarily close to the ...
  • Ciortan, Irina; Pintus, Ruggero; Marchioro, Giacomo; Daffara, Claudia; Giachetti, Andrea; Gobbetti, Enrico (the Eurographics Association, 2016-10)
    We present a practical acquisition and processing pipeline to characterize the surface structure of cultural heritage objects. Using a free-form Reflectance Transformation Imaging (RTI) approach, we acquire multiple digital ...
  • Pintus, Ruggero; Gobbetti, Enrico; Callieri, Marco; Dellepiane, Matteo (Springer, 2017-04-12)
    Today’s most widely used 3D digitization approach is a combination of active geometric sensing, mainly using laser scanning, with active or passive color sensing, mostly using digital photography. Producing a seamless ...
