Researchers use AI and 3D printing to recreate paintings from photographs

Researchers at the MIT Computer and Artificial Intelligence Laboratory have created a system capable of reproducing paintings from a single photograph, thus enabling museums and art enthusiasts alike. art to take their favorite photos and print new copies with paint textures.

Called RePaint, the project uses machine learning to recreate the exact colors of each painting, and then prints it with the help of a high-end 3D printer that can generate thousands half-tone colors.

However, researchers have found a better way to capture a more complete spectrum of Degas and Dali. They used a special technique that they developed, called "color-contoning," which involves using a 3D printer and 10 different transparent inks stacked in very thin layers, much like wafers and chocolate. a Kit-Kat bar. They combined their method with a decades-old technique called "half-tones", in which an image is created by tons of small dots of ink, rather than continuous tones. According to the team, combining these elements makes it easier to capture the nuances of the colors.

"If you simply reproduce the color of a painting as it appears in the gallery, its appearance might be different at home," said researcher Changil Kim. "Our system works in all lighting conditions, which shows a much higher color reproduction capacity than almost any previous work."

Unfortunately, the prints have barely the size of a business card. The system can not yet support matte finishes and detailed surface textures, but the team is working on improving algorithms and 3D printing technology so you can finally recreate that image of dogs playing on 3D plastic poker.
