Po stanoven\u00ed mno\u017einy identifika\u010dn\u00edch komponent bylo nutn\u00e9 rozhodnout, kter\u00e9 pam\u00e1tky budou slou\u017eit k napln\u011bn\u00ed datov\u00e9 sady. S ohledem na p\u0159eshrani\u010dn\u00ed spolupr\u00e1ci jsme zvolili v \u010desko-bavorsk\u00e9m p\u0159\u00edhrani\u010d\u00ed celkem 130 kostel\u016f, kter\u00e9 by byly\n vhodn\u00e9 ke strojov\u00e9mu u\u010den\u00ed.<\/p>\n

Po f\u00e1zi zvolen\u00ed vhodn\u00fdch kostel\u016f, n\u00e1sledovala mnoham\u011bs\u00ed\u010dn\u00ed etapa fotografov\u00e1n\u00ed interi\u00e9r\u016f a exteri\u00e9r\u016f kostel\u016f. Celkem bylo takto po\u0159\u00edzeno 6821 fotografi\u00ed.

Filtrem kvality se k dal\u0161\u00edmu kroku zpracov\u00e1n\u00ed dostalo 4496 fotografi\u00ed.<\/p>\n

N\u00e1sledn\u011b bylo nutn\u00e9 v\u0161echny vhodn\u00e9 fotografie zpracovat a ru\u010dn\u011b na nich ozna\u010dit jednotliv\u00e9 komponenty.

Pomoc\u00ed t\u00e9to aplikace byly vyb\u00edr\u00e1ny na fotografi\u00edch jednotliv\u00e9 komponenty\n a aplikace je ukl\u00e1dala do samostatn\u00fdch obrazov\u00fdch soubor\u016f.
