Rembrandtovo van Rijnovo ikonick\u00e9 d\u00edlo “No\u010dn\u00ed hl\u00eddka” zachycuje dynamickou sc\u00e9nu amsterdamsk\u00fdch milicion\u00e1\u0159\u016f p\u0159ipravuj\u00edc\u00edch se k boji.

Av\u0161ak v roce 1715 byly \u010d\u00e1sti pl\u00e1tna od\u0159\u00edznuty, aby se obraz ve\u0161el do amsterdamsk\u00e9 radnice. Tyto ztracen\u00e9 okraje z\u016fst\u00e1valy po stalet\u00ed z\u00e1hadou.<\/p>\n\n
V roce 2019 zah\u00e1jilo Rijksmuseum mnohamilionov\u00fd restaura\u010dn\u00ed projekt s n\u00e1zvem “Operace No\u010dn\u00ed hl\u00eddka” s c\u00edlem obnovit p\u016fvodn\u00ed velikost obrazu. Odborn\u00edci pou\u017eili kombinaci pokro\u010dil\u00fdch technologi\u00ed, v\u010detn\u011b skener\u016f, rentgenov\u00fdch paprsk\u016f a 528 digit\u00e1ln\u00edch sn\u00edmk\u016f.<\/p>\n\n
Kl\u00ed\u010dovou inovac\u00ed v procesu restaurov\u00e1n\u00ed bylo pou\u017eit\u00ed um\u011bl\u00e9 inteligence (AI).

Krom\u011b um\u011bl\u00e9 inteligence odborn\u00edci tak\u00e9 studovali Gerritovu Lundensovu kopii “No\u010dn\u00ed hl\u00eddky” ze 17. stolet\u00ed, kter\u00e1 slou\u017eila jako vod\u00edtko p\u0159i restaurov\u00e1n\u00ed.
