    • Crack Detection in Single- and Multi-Light Images of Painted Surfaces using Convolutional Neural Networks 

      Dulecha, Tinsae; Giachetti, Andrea; Pintus, Ruggero; Ciortan, Irina-Mihaela; Jaspe Villanueva, Alberto; Gobbetti, Enrico (Chapter, 2019)
      Cracks represent an imminent danger for painted surfaces that needs to be alerted before degenerating into more severe aging effects, such as color loss. Automatic detection of cracks from painted surfaces' images would ...

    • Fluorescence Transformation Imaging 

      Ciortan, Irina-Mihaela; Giachetti, Andrea; George, Sony; Hardeberg, Jon Yngve (Chapter, 2021)
      Fluorescence is a photoluminescence phenomenon where light is absorbed at lower wavelengths and re-emitted at longer wavelengths. For classic artworks, fluorescence gives useful information about varnish and retouches. At ...

    • State-of-the-art in Multi-Light Image Collections for Surface Visualization and Analysis 

      Pintus, Ruggero; Dulecha, Tinsae; Ciortan, Irina-Mihaela; Gobbetti, Enrico; Giachetti, Andrea (Peer reviewed; Journal article, 2019)
      Multi‐Light Image Collections (MLICs), i.e., stacks of photos of a scene acquired with a fixed viewpoint and a varying surface illumination, provide large amounts of visual and geometric information. In this survey, we ...
