  • Practical Free-form RTI Acquisition with Local Spot Lights 
    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 ...
  • A Practical Reflectance Transformation Imaging Pipeline for Surface Characterization in Cultural Heritage 
    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 ...
  • Techniques for seamless color registration and mapping on dense 3D models 
    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 ...
