Computer program reveals artists' influences

Program designers started with a close look at 1,710 paintings. For each work, the program logged the everyday items depicted, such as chairs and stoves, as well as features including color, composition and brushstroke. By comparing lists of these features with lists made from reference paintings, the program figured out the style of unknown paintings about 70 percent of the time, computer scientist Ahmed Elgammal and colleagues at Rutgers University in Piscataway, N.J.,report August 19 in Multimedia Tools and Applications.

The program’s analyses could offer historians a new way to look at artists’ influences, Elgammal says. Among other links, the program proposed a connection between French impressionist Frédéric Bazille and American painting icon Norman Rockwell.

As the titles suggest, Diego Velázquez’s 1650 Portrait of Pope Innocent X (left) figured prominently in Francis Bacon’s 1953 Study After Velázquez’s Portrait of Pope Innocent X (right).

Bazille’s 1870 Studio 9 Rue de la Condamine (at left in slideshow above) and Rockwell’s 1950 Shuffleton’s Barbershop (at right in slideshow above) look alike to the program. The two paintings have similar compositions (red lines) and objects (circled), along with a similarly positioned window (blue rectangles).

But the likeness may just be a coincidence, says Princeton art historian Emily Spratt. Two stylistically similar paintings don’t ensure the artists are historically related, she says. Still, she can imagine a program that looks at a painting and spits out information about the image and its place in history: “Maybe in the future, with computer vision technology, you could actually have a pocket art historian.”
