Using X-rays, artificial intelligence and 3D printing, two UCL researchers reproduced a “lost” work of art by renowned Dutch painter Vincent Van Gogh, 135 years after he painted over it.

PhD researchers Anthony Bourached (UCL Queen Square Institute of Neurology) and George Cann (UCL Space and Climate Physics), working with artist Jesper Eriksson, used cutting edge technology to recreate a long-concealed Van Gogh painting.

Researchers train AI to attribute paintings based on detailed brushstroke analysis

Art historians may have a new tool for settling the attribution of disputed paintings using artificial intelligence (AI) thanks to research by a cross-disciplinary team led by physicists at Case Western Reserve University in Cleveland, Ohio. The research, published in November in the journal Heritage Science, shows how machine learning analysis of small sections of topographical scans of paintings—some as tiny as half a millimeter—was able to attribute the works to the correct artist with up to 96% accuracy.
