    • Spatio–Temporal Retinex–Inspired Envelopes with Anisotropic Diffusion 

      Sagvold, Petter; Farup, Ivar; Pedersen, Marius (Peer reviewed; Journal article, 2023)
      Since the introduction of the Retinex theory by Land and McCann in 1971, a multitude of different families, versions, interpretations, implementations, and applications have been proposed. The applications for image ...

    • Spectral Adaptation Transform for Multispectral Constancy 

      Khan, Haris Ahmad; Thomas, Jean-Baptiste; Hardeberg, Jon Yngve; Laligant, Olivier (Journal article; Peer reviewed, 2018)
      The spectral reflectance of an object surface provides valuable information of its characteristics. Reflectance reconstruction from multispectral image data is typically based on certain assumptions. One of the common ...

    • Spectral Estimation: Its Behaviour as a SAT and Implementation in Colour Management 

      Habib, Tanzima; Green, Philip John; Nussbaum, Peter Stefan (Peer reviewed; Journal article, 2023)
      Methods for estimating spectral reflectance from XYZ colorimetry were evaluated using a range of different types of training datasets. The results show that when a measurement dataset with similar primary colorants (and ...

    • Statistical Analysis of Sparkle in Snow Images 

      Nguyen, Mathieu; Thomas, Jean Baptiste; Farup, Ivar (Peer reviewed; Journal article, 2022)
      Sparkle from snow is a common phenomenon in Nature but not well studied in the literature. We perform a statistical study on digital snow images captured in-situ to analyze sparkle events by using contrast and density of ...

    • Toward Solving a Puzzle of Fragmented Archeological Textiles 

      Gigilashvili, Davit; Gulbrandsen, Casper Fabian; Nguyen, Ha Thu; Havgar, Margrethe; Vedeler, Marianne; Hardeberg, Jon Yngve (Peer reviewed; Journal article, 2024)
      Archeological textiles can provide invaluable insight into the past. However, they are often highly fragmented, and a puzzle has to be solved to re-assemble the object and recover the original motifs. Unlike common jigsaw ...

    • Using a Behavioral Match-to-Sample Method to Evaluate Color Vision Deficiency Simulation Methods 

      Simon-Liedtke, Joschua Thomas; Farup, Ivar (Journal article; Peer reviewed, 2016)
      Color vision deficiency (CVD) simulation methods are used both to simulate color vision of color-deficient people and as input for image enhancement methods for the color-deficient. However, a standardized method to compare ...
