• A Lightweight Payload for Hyperspectral Remote Sensing using Small UAVS 

      Fortuna, João; Johansen, Tor Arne (Journal article; Peer reviewed, 2018)
      In this paper we describe a lightweight hyperspectral imaging payload consisting of a push-broom imager, GPS and IMU sensors as well as data synchronization and acquisition systems. The payload is developed in a modular ...
    • Fully Constrained Least Squares Linear Spectral Unmixing of The Scream (Verso, 1893) 

      Deborah, Hilda; Ulfarsson, Magnus Orn; Sigurdsson, Jakob (Peer reviewed; Journal article, 2021)
      Taking insights from the remote sensing field, in the recent decade, the advantages of hyperspectral imaging technology has been exploited for painting conservation. The estimation of pigment proportion in painting is a ...
    • A Metrological Framework for Hyperspectral Texture Analysis Using Relative Spectral Difference Occurrence Matrix 

      Chu, Rui Jian; Richard, Noel; Ghorbel, Faouzi; Fernandez-Maloigne, Christine; Hardeberg, Jon Yngve (Peer reviewed; Journal article, 2019)
      A new hyperspectral texture descriptor, Relative Spectral Difference Occurrence Matrix (RSDOM) is proposed. Developed in a metrological framework, it simultaneously considers the distribution of spectra and their spatial ...
    • Morphological Texture Description For Hyperspectral Images: Pattern Spectrum 

      Deborah, Hilda; Richard, Noël (Peer reviewed; Journal article, 2021)
      A metrological extension of morphological granulometry for the hyperspectral domain is introduced in this work. This development is enabled by the latest study of a suitable ordering relation for hyperspectral images. With ...
    • Real-time Corrections for a Low-cost Hyperspectral Instrument 

      Henriksen, Marie Bøe; Garrett, Joseph; Prentice, Elizabeth Frances; Sigernes, Fred; Stahl, Annette; Johansen, Tor Arne (Journal article; Peer reviewed, 2019)
      The development of a hyperspectral imager (HSI) made from commercial off-the-shelf (COTS) parts enables the use of hyperspectral imaging on smaller low-cost platforms such as cubesats, drones, or other autonomous vehicles. ...
    • Simulation tool for hyper-spectral imaging from a satellite 

      Lapadatu, Monica; Bakken, Sivert; Grøtte, Mariusz Eivind; Alver, Morten; Johansen, Tor Arne (Journal article; Peer reviewed, 2019)
      This paper presents a tool created for simulating the expected radiance from oceanic geophysical parameters through the atmosphere as perceived by a hyperspectral remote sensing satellite. The effects of varying off-nadir ...
