a Distribution of Euclidean distance calculated between physically cleaned artwork and the virtually cleaned one using (a) physics-based model, b DGN (the first experiment) and c DGN (the second experiment). Distribution of spectral angle calculated between the physically cleaned artwork and the virtually cleaned one using d the physics-based model, e DGN (the first experiment) and f DGN (the second experiment)
