Fig. 7From: Tensor decomposition for painting analysis. Part 2: spatio-temporal simulationAbundance maps, estimated with the least-square method, of endmembers 1–6 (previously extracted with the tensor decomposition model from the microfading data) in the hyperspectral image of the central lantern. Endmember 1 seems to be the pigment most uniformly distributed. This hints to its application as an underneath layer, beneath the rest of the colorsBack to article page
