PARIS: The hypercolour image of a dark hill and lava flow is pretty enough — but its high-tech artificial intelligence origins make it special.

It is the product of the brainwaves of one member of French art collective Obvious, collected in an MRI machine at the Brain Institute of the Pitie Salpetriere hospital in Paris. “I was thinking very hard about a volcano,” said Pierre Fautrel, one of the trio.

He admits the resulting work was not exactly what he had in mind, “but it has kept the basic elements: a flaming mountain with flowing lava and a landscape on a light background”.

The trio of thirty-somethings, Fautrel, Hugo Caselles-Dupre and Gauthier Vernier, already gained international attention in 2018 by selling an AI-generated artwork at Christie’s in New York for more than 400,000 euros.

For the latest project, “Mind to Image”, they used an open-source programme, MindEye, which is able to retrieve and reconstruct viewed images from brain activity, combining it with their own AI programme to create artworks.

They tried two different versions — one in which they looked at pictures and tried to replicate them simply through their brainwaves captured in the MRI. They also tried recreating their invented images based on written descriptions.

For each, they repeated the process many times over 10 hours to create a database for their AI.

“We’ve known for around 10 years that it’s possible to reconstruct a viewed image from the activity of the visual cortex,” said Alizee Lopez-Persem, a researcher at the Brain Institute.
