    • Curve-Based Classification Approach for Hyperspectral Dermatologic Data Processing 

      Uteng, Stig; Quevedo, Eduardo; Callico, Gustavo M.; Castaño, Irene; Carretero, Gregorio; Almeida, Pablo; Garcia, Aday; Hernandez, Javier A.; Godtliebsen, Fred (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-20)
      This paper shows new contributions in the detection of skin cancer, where we present the use of a customized hyperspectral system that captures images in the spectral range from 450 to 950 nm. By choosing a 7 × 7 sub-image of each channel in the hyperspectral image (HSI) and then taking the mean and standard deviation of these sub-images, we were able to make fits of the resulting curves. These ...

    • Early Detection of Change by Applying Scale-Space Methodology to Hyperspectral Images 

      Uteng, Stig; Johansen, Thomas Haugland; Zaballos, Jose Ignacio; Ortega, Samuel; Holmström, Lasse; Callico, Gustavo M.; Fabelo, Himar; Godtliebsen, Fred (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-27)
      Given an object of interest that evolves in time, one often wants to detect possible changes in its properties. The first changes may be small and occur in different scales and it may be crucial to detect them as early as possible. Examples include identification of potentially malignant changes in skin moles or the gradual onset of food quality deterioration. Statistical scale-space methodologies ...
