    • Performance evaluation of no-reference image quality metrics for face biometric images 

      Liu, Xinwei; Pedersen, Marius; Charrier, Christophe; Bours, Patrick (Journal article; Peer reviewed, 2018)
      The accuracy of face recognition systems is significantly affected by the quality of face sample images. The recent established standardization proposed several important aspects for the assessment of face sample quality. ...

    • Preferred image quality metric for shifted superimposition-based resolution-enhanced images 

      Hansen, Svein Arne Jervell; Akram, Muhammad Nadeem; Hardeberg, Jon Yngve; Pedersen, Marius (Journal article; Peer reviewed, 2018)
      Shifted superimposition is a resolution-enhancement method that has gained popularity in the projector industry the last couple of years. This method consists of shifting every other projected frame spatially with subpixel ...

    • Termite retinex: A new implementation based on a colony of intelligent agents 

      Simone, Gabriele; Audino, Giuseppe; Farup, Ivar; Albregtsen, Fritz; Rizzi, Alessandro (Journal article; Peer reviewed, 2014)
      Abstract. The original presentation of Retinex, a spatial color correction and image enhancement algorithm modeling the human vision system, as proposed by Land and McCann in 1964, uses paths to explore the image in search ...

    • Visual and data stationarity of texture images 

      Conni, Michele; Deborah, Hilda; Nussbaum, Peter; Green, Philip John (Peer reviewed; Journal article, 2021)
      The stationarity of a texture can be considered a fundamental property of images, although the property of stationarity is difficult to define precisely. We propose a stationarity test based on multiscale, locally stationary, ...
