| Researchers from TU Delft discover real Van Gogh using artificial intelligence |
Snow-Covered Field with a Harrow
One of the paintings the TU Delft researcher Jan van der Lubbe regularly refers to when this subject is discussed, is Snow-Covered Field with a Harrow (after Millet)
which can be seen in the Van Gogh Museum. ‘That work’s colours have
faded. The edges of the painting, which were protected by the frame,
show that the dominant green was originally more purple,’ explains Van
der Lubbe. ‘In collaboration with various partners, the museum is trying
to digitally reconstruct changes like these. This applies to drawings
too. And we're helping them.’...
Voyage of Discovery
The
research focuses, amongst other things, on the reconstruction of a Van
Gogh drawing. Van der Lubbe explains: ‘You could start off with an
explicit model, but this would be like working with a mathematical
formula: you feed it something, and it spits out something. Neural
networks, however, are implicit. You make observations and then allow a
learning method to work out the relationships between various
parameters. All this data allows a method like CNN to predict what an
old drawing would have looked like years ago. It's a way of going back
from the present to the original year of manufacture of the drawing,
using knowledge from the past. What we do is actually a voyage of
discovery. We want to understand to what extent a reconstruction like
this can be arrived at using a learning method.’
