    • Predicting Pigment Color Degradation with Time Series Models 

      Ciortan, Irina-Mihaela; Poulsson, Tina Grette; George, Sony; Hardeberg, Jon Yngve (Chapter, 2022)
      The colors of pigments and dyes are affected by light exposure. Light-induced color change has an impact on various industrial and artistic applications where colored materials are frequently exposed to light throughout ...

    • Tensor decomposition for painting analysis. Part 1: pigment characterization 

      Ciortan, Irina-Mihaela; Poulsson, Tina Grette; George, Sony; Hardeberg, Jon Yngve (Journal article; Peer reviewed, 2023)
      Photo-sensitive materials tend to change with exposure to light. Often, this change is visible when it affects the reflectance of the material in the visible range of the electromagnetic spectrum. In order to understand ...

    • Tensor decomposition for painting analysis. Part 2: spatio-temporal simulation 

      Ciortan, Irina-Mihaela; Poulsson, Tina Grette; George, Sony; Hardeberg, Jon Yngve (Journal article; Peer reviewed, 2023)
      In a previous article, we modelled the spectral and temporal dimensions of the photodegradation behaviour of pigments in the painting “A Japanese Lantern” by Oda Krohg. In particular, we extracted the endmembers and spectral ...
