  • 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 ...
