Abstract

Izgudrojums attiecas uz digitālo krāsu attēlu apstrādes paņēmienu, konkrēti – uz vairāk kā triju atšķirīgām spektra joslām atbilstošu attēlu selekciju no viena RGB attēla datu masīva. Piedāvātajā paņēmienā multispektrālu attēlu iegūšanai objektu apgaismo vienlaikus vairākās spektra joslās un identificē katrā attēla pikselī „i” reģistrētās Ri-, Gi- un Bi-signālu vērtības. Tālāk tās salīdzina gan savā starpā, gan ar ārēji uzdotu signālu diskriminācijas līmeni S, kurš pie jebkura viļņu garuma sensora spektrālās jūtības apgabalā pieļauj tikai vienas vai divu R, G un/vai B joslu reģistrāciju. Spektrālo attēlu skaita palielināšanas nolūkos S vērtības tiek nepārtraukti mainītas līdz visaugstākajai no iespējamām R, G vai B joslu signālu vērtībām pie nosacījuma, ka šajā intervālā tiek nodrošināta sensora fotojutības linearitāte. Atkarībā no S vērtības tiek analizētas divas situācijas – kad i-pikselī ir reģistrēti signāli vienlaikus divās krāsu joslās (B un G, G un R vai B un R) vai kad tie ir reģistr&ema
