      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 ...

    • Turning a Digital Camera into an Absolute 2D Tele‐Colorimeter 

      Guarnera, Giuseppe Claudio; Bianco, Simone; Schettini, Raimondo (Journal article; Peer reviewed, 2018)
      We present a simple and effective technique for absolute colorimetric camera characterization, invariant to changes in exposure/aperture and scene irradiance, suitable in a wide range of applications including image‐based ...
