    • Analysis of individual quality scores of different image distortions 

      Cherepkova, Olga; Amirshahi, Seyed Ali; Pedersen, Marius (Peer reviewed; Journal article, 2022)
      In this paper, we study individual quality scores given by different observers for various image distortions (saturation, contrast, and color quantization) at different levels. We created a database that contains a total ...

    • Benchmarking modern gloss correlators with established ISO 2813 standard and visual judgement of gloss 

      Saric, Donatela; Kraushaar, Andreas; Mattuschka, Marco; Green, Philip John (Journal article; Peer reviewed, 2021)

    • Colourlab Image Database: Geometric Distortions 

      Pedersen, Marius; Amirshahi, Seyed Ali (Peer reviewed; Journal article, 2021)
      Over the years, a high number of different objective image quality metrics have been proposed. While some image quality metrics show a high correlation with subjective scores provided in different datasets, there still ...

    • Estimation of BRDF Measurements for Printed Colour Samples 

      Habib, Syeda Tanzima; Green, Philip John; Nussbaum, Peter (Journal article; Peer reviewed, 2021)
      In this paper, we describe a method to estimate BRDF measurements for different printed colours, using just the BRDF measurements of the substrate and the primary inks. A model is trained using the BRDF measurements of the ...

    • How Good is Too Good? A Subjective Study on Over Enhancement of Images 

      Azimian, Sahar; Torkamani-Azar, Farah; Amirshahi, Seyed Ali (Peer reviewed; Journal article, 2021)
      For a long time different studies have focused on introducing new image enhancement techniques. While these techniques show a good performance and are able to increase the quality of images, little attention has been paid ...

    • Image-based goniometric appearance characterisation of bronze patinas 

      Kiyomoto Arteaga, Isabel Yoko; Boust, Clotilde; Dequier, Angèle; Hardeberg, Jon Yngve (Journal article; Peer reviewed, 2021)
      Patinas are a form of metal polychromy used to decorate metallic artworks. Due to the nature of the metallic surface, their colour and gloss is perceived differently when the illumination and viewing directions vary. Sparkle ...

    • Perceived Translucency at Different Spatial Scales in Color and Grayscale Images 

      Hassan, Aqsa; Gigilashvili, Davit (Peer reviewed; Journal article, 2023)
      Many objects and materials in our daily lives are translucent. Translucency is an important attribute of appearance together with color, gloss, and texture. However, it remains largely unexplored whether and how these ...

    • Perceptual Navigation in Absorption-Scattering Space 

      Gigilashvili, Davit; Urban, Philipp; Thomas, Jean Baptiste; Pedersen, Marius; Hardeberg, Jon Yngve (Peer reviewed; Journal article, 2021)
      Translucency optically results from subsurface light transport and plays a considerable role in how objects and materials appear. Absorption and scattering coefficients parametrize the distance a photon travels inside the ...

    • Radiometric spectral fusion of VNIR and SWIR hyperspectral cameras 

      Grillini, Federico; Thomas, Jean Baptiste; George, Sony (Peer reviewed; Journal article, 2021)
      When two hyperspectral cameras are sensitive to complementary portions of the electromagnetic spectrum it is fundamental that the calibration processes conducted independently lead to comparable radiance values, especially ...

    • Reflectance estimation from snapshot multispectral images captured under unknown illumination 

      Kitanovski, Vlado; Thomas, Jean Baptiste; Hardeberg, Jon Yngve (Peer reviewed; Journal article, 2021)
      Multispectral images contain more spectral information of the scene objects compared to color images. The captured information of the scene reflectance is affected by several capture conditions, of which the scene illuminant ...

    • The Role of Shape in Modeling Gloss 

      Gigilashvili, Davit; Islam, Akib Jayed (Peer reviewed; Journal article, 2022)
      Gloss is an important appearance attribute, and its exact perceptual mechanisms are yet to be fully understood. Previous works attempted to model the relationship between optical and perceptual gloss. The state-of-the-art ...

    • Standard representation space for spectral imaging 

      Thomas, Jean-Baptiste Denis; Lapray, Pierre-Jean; Derhak, Max; Farup, Ivar (Peer reviewed; Journal article, 2023)
