X-rays, AI and 3D printing bring lost Van Gogh Artwork to life

by University College London

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.

Ph.D. 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.

It's the latest in their "NeoMasters" series of recreations, a project they've been working on since 2019 to bring lost works of art to life.

They developed a process to recreate lost works that uses X-ray imaging to see through every layer of paint, AI to extrapolate the artist's style, and 3D printing to fabricate the final piece.

This newest effort, dubbed "The Two Wrestlers," depicts two shirtless wrestlers grappling in front of an abstract background. It recreates a painting originally by Van Gogh who covered over the two figures when he reused the canvas for an unrelated painting of flowers.

Bourached, who is researching Machine Learning and Behavioral Neuroscience at UCL, says that "how much it is like the original painting is impossible to tell at this point because the information doesn't exist. I think it's very convincing—by far the best guess we can get with current technology."

The obscured image was first discovered in 2012 when art experts at the University of Antwerp investigated whether the work "Still Life with Meadow Flowers and Roses" was an authentic Van Gogh. The researchers examining the artwork used X-rays to peer through the layers of paint and discovered two ghostly figures that had been painted over.

The covered-over wrestlers displayed brush strokes and pigments that were consistent with Van Gogh, and the subject matter was also a common theme at the Antwerp Art Academy where Van Gogh was studying in 1886, authenticating the work. ... '

Restoring Notre-Dame with VR

Very impressive imagery on current state and progress of Notre-Dame Damage and restoration. Certainly a model for future work of this kind.  Includes video describing work.

Cathédrale Notre-Dame Rescue Is Buttressed by Digital Wizardry  By Financial Times, February 17, 2021  in ACM

Art historians, architects, computer scientists, and digital designers from around the world are leveraging virtual reality (VR), three-dimensional modeling, and cloud computing technologies to create a "virtual twin" of the Notre-Dame cathedral in Paris, France, as part of its reconstruction following a 2019 fire.

The simulated cathedral will display the progress in real time using images streamed from inside the cathedral by robot-sentries outfitted with cameras. Engineers and experts on medieval architecture can move through the simulation while wearing VR headsets. Architectural drawings, post-fire scientific reports, and the provenance of specific building components can be accessed by clicking on any detail.

Artificial intelligence agents also are moving quickly through pre- and post-fire images to identify surviving sculpted and limestone elements that could be reintegrated into the site.

These techniques could be used to preserve ancient architecture virtually, reconstruct centuries-old sites, or create virtual museums for iconic cultural sites.
