    • Towards Spectral Mathematical Morphology 

      Deborah, Hilda (Doctoral theses at NTNU;2016:372, Doctoral thesis, 2016)
      Providing not only spatial information but also spectral measures as a function of wavelength, hyperspectral imaging boasts a much greater accuracy than traditional grayscale and color imaging. For this capability, ...
    • Unsupervised clustering for works of art using hyperspectral imaging: A case study on Edvard Munch's Self-Portrait (1905) 

      Mandal, Dipendra Jee; Deborah, Hilda; George, Sony; Hardeberg, Jon Yngve (Journal article; Peer reviewed, 2023)
      The study of pigments in historical works of art is of significant value for conservators and art historians, providing insight into artistic techniques and the preservation of cultural heritage. Hyperspectral imaging aids ...
    • 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, ...
