HOW DOES A COM­PUTER BE­COME REM­BRANDT?

A com­puter spent 1.5 years learn­ing the tech­niques of Rem­brandt. In the end it was able to pro­duce a new im­age that looks like an orig­i­nal. Be­low are the five steps to a gen­er­ated mas­ter­piece:

DATA SCAN

Each of Rem­brandt’s works is scanned three-di­men­sion­ally. In this way a to­tal of 150 gi­ga­bytes of data are col­lected.

DIVI­SION

The soft­ware then par­ti­tions all the scanned im­ages into more than 60 dif­fer­ent ar­eas, like ears, eyes, etc.

ANAL­Y­SIS

By com­par­ing the data the com­puter “learns” how Rem­brandt paints noses, for ex­am­ple, and this gives rise to al­go­rithms.

CRE­ATION

Mouth, fore­head, cloth­ing— each in­di­vid­ual fea­ture is “in­vented” by the com­puter in a 500-hour process.

PRINT

A 3-D printer brings 148 mil­lion pix­els to life by de­posit­ing 13 pig­ment lay­ers onto a pad. (See the im­age at top right.) The fin­ished prod­uct is like oil on can­vas.
