    • Appearance Manipulation in Spatial Augmented Reality using Image Differences 

      Gigilashvili, Davit; Trumpy, Giorgio (Peer reviewed; Journal article, 2022)
      Rapidly emerging augmented reality technologies enable us to virtually alter appearance of objects and materials in a fast and efficient way. The state-of-the-art research shows that the human visual system has a poor ...

    • Digital Unfading of Chromogenic Film Informed by Its Spectral Densities 

      Chatterjee, Sreya; Trumpy, Giorgio; Ruedel, Ulrich (Peer reviewed; Journal article, 2023)
      A material-based approach for the digital restoration of chromogenic photographic and film materials affected by dye fading is proposed. Through a digital reconstruction of the original optical properties, the proposed ...

    • Effect of Luminance Adaptation on Contrast Threshold in HVS 

      Harijan, Akash (Master thesis, 2023)
      A psychophysical experiment was conducted to investigate the effect of surround luminance i.e. luminance out of 10 degrees visual angle of the retina, on luminance contrast in foveal view by the human visual system (HVS) ...

    • High Dynamic range imaging for dual-RGB system for cultural heritage 

      Syed, Ali Raza (Master thesis, 2023)
      This thesis work explores the usage of a dual-RGB multispectral imaging setup for enhancing the colour accuracy of photographic films capture. A dual-RGB multispectral imaging system captures two images from a trichromatic ...

    • Mapping Quantitative Observer Metamerism of Displays 

      Trumpy, Giorgio; Andersen, Casper Find; Farup, Ivar; Elezabi, Omar (Journal article; Peer reviewed, 2023)
      Observer metamerism (OM) is the name given to the variability between the color matches that individual observers consider accurate. The standard color imaging approach, which uses color-matching functions of a single ...

    • Using Spatial Augmented Reality to Increase Perceived Translucency of Real 3D Objects 

      Trumpy, Giorgio; Gigilashvili, Davit (Journal article, 2023)
      Translucency is an important optical and perceptual attribute that has a significant impact on the appearance of objects and materials. Expensive and time-consuming manufacturing process is required to produce a translucent ...
