‘Lost’ Picasso nude re-created, with help from AI

Before he became famous, Pablo Picasso didn’t always have money for art materials, so, like other struggling artists, he’d paint over existing canvases to create new works, thus concealing the earlier images.  

One such painting, cloaked under another for more than a century, has gotten new life, thanks to AI.   

It’s a painting of a nude woman, dubbed The Lonesome Crouching Nude. In 2010, X-rays revealed it hidden beneath Picasso’s 1903 oil painting The Blind Man’s Meal, considered one of the most important works from the artist’s expressionist Blue Period. During that time, he painted somber monochromatic works in blue and blue-green hues, with occasional highlights of warm tones like rust or gold. 

Picasso rendered the crouching nude woman in characteristic Blue Period tones, as is evidenced by a full-size, full-color re-creation that replicates the painting down to 3D brushstrokes. It’s on display through Sunday at the inaugural Deeep AI art fair from the London-based Morf Gallery, which describes itself as a futuristic online gallery showcasing limited-edition fine art. 

Researchers from University College London re-created the painting using an original algorithm that studied dozens of Picasso’s paintings and trained itself in the Spanish artist’s style.  

“It’s quite eerie seeing the brushstrokes, the color and the way in which lights reflects off the work,” said George Cann, one of two UCL Ph.D. researchers who brought the 20th century piece back to life with modern tools. “It’s a beautiful piece.”

It was also likely significant to the artist. The crouching woman appears in the background of another famous Picasso Blue Period piece, La Vie (The Life). 

“The fact that the woman within The Lonesome Crouching Nude is also within La Vie and a few of Picasso’s sketches suggests that Picasso may have had an affinity towards this woman,” Cann said in a statement.   

Cann and fellow UCL doctoral candidate Anthony Bourached have created a system for reproducing art that’s been painted over. The tools include X-ray and/or infrared imagery to reveal the hidden work; a neural network that can reproduce the work after studying the artist’s cache; a heightmap for elevation modeling; and a 3D printer for printing a textured piece. Cann and Bourached call their art reconstruction initiative Oxia Palus, and they’ve applied it to works including another hidden Picasso, La Femme Perdue, as well as a lost Modigliani. 

“I believe Picasso actively welcomed such forensics,” Bourached said, “since he himself said, ‘I just painted the images that rose before my eyes. It is for other people to find the hidden meanings.'”  

The Lonesome Crouching Nude isn’t the first hidden painting from Picasso’s Blue Period to be revealed. In 2014, infrared imaging unveiled a portrait of a bearded man underneath another Blue Period work, The Blue Room, which depicts a woman bathing.
