HOW DOES A COM­PUTER BE­COME REM­BRANDT?

World of Knowledge (Australia) - - Technology -

A com­puter spent one and a half years study­ing Rem­brandt’s tech­nique. The re­sult? A brand new im­age that looks like an old mas­ter. The five steps to a gen­er­ated mas­ter­piece are: DATA SCAN Ev­ery Rem­brandt art­work is scanned in 3D, pro­duc­ing 160 gi­ga­bytes of data in to­tal. DE­TAILS The soft­ware analy­ses the im­ages in more than 60 dif­fer­ent ar­eas like the ears and eyes.

ANAL­Y­SIS By com­par­ing data and cre­at­ing al­go­rithms the com­puter learns how Rem­brandt painted the nose. CRE­ATION Mouth, fore­head, cloth­ing – ev­ery in­di­vid­ual char­ac­ter­is­tic is ‘ren­dered’ by the com­puter. This process alone took 500 hours.

PRINT A 3D printer lays down 13 lay­ers of ink to cre­ate tex­ture (top right). This makes the im­age look like oil painted on can­vas.
