Rembrandt created one of these portraits, a computer created the other. Can you tell which is which?

In Amsterdam this month, a team of computer scientists and Rembrandt experts unveiled a new portrait that looks alarmingly similar to the work of the famed Dutch artist.

The portrait of a man wearing a broad hat is the latest example of how advanced computer methods are making it increasingly easy to mimic the style of history’s most acclaimed artists. Art that hangs in museums, sells for millions and that has endured for generations is being emulated by computer wizards without the pedigree of Rembrandt and kin.

When lined up against Rembrandt’s work, it can be difficult to tell which portrait a machine created and which the Dutch painter created roughly 400 years ago.

The creators of the “new Rembrandt” used computers to 3D scan and analyze 346 Rembrandt paintings. Next, they used facial recognition software to identify the most common geometric patterns Rembrandt used. Once their computer system had learned this, it could replicate the style and create new facial features.

The process relies on a hot field in technology, deep learning, in which machines are fed massive amounts of data and are able to suss out patterns and then mimic them in new creations.

The team decided to create a portrait of a white male in his 30s with facial hair, dark clothes and a white collar, because those traits were so common in Rembrandt’s work. They generated the facial features individually and then assembled them into a face. The distance between features were based off calculations of what was typical in Rembrandt’s other works.
