    • Reflectance Transformation Imaging as a Tool for Computer-Aided Visual Inspection 

      Zendagui, Abir; Le Goïc, Gaëtan; Chatoux, Hermine; Thomas, Jean Baptiste; Jochum, Pierre; Maniglier, Stéphane; Mansouri, Alamin (Peer reviewed; Journal article, 2022)
      This work investigates the use of Reflectance Transformation Imaging (RTI) rendering for visual inspection. This imaging technique is being used more and more often for the inspection of the visual quality of manufactured ...

    • Reflectance-based surface saliency 

      Pitard, Gilles; Le Goïc, Gaëtan; Mansouri, Alamin; Favreliére, Hugues; Pillet, Maurice; George, Sony; Hardeberg, Jon Yngve (Journal article; Peer reviewed, 2018)
      In this paper, we propose an original methodology allowing the computation of the saliency maps for high dimensional RTI data (Reflectance Transformation Imaging). Unlike most of the classical methods, our approach aims ...

    • Robust Anomaly Detection Using Reflectance Transformation Imaging for Surface Quality Inspection 

      Pitard, Gilles; Le Goïc, Gaëtan; Mansouri, Alamin; Favreliére, Hugues; Pillet, Maurice; George, Sony; Hardeberg, Jon Yngve (Chapter, 2017)
      We propose a novel methodology for the detection and analysis of visual anomalies on challenging surfaces (metallic). The method is based on a local assessment of the reflectance across the inspected surface, using Reflectance ...
