Ukuhlukaniswa kwesikhumba kukaFitzpatrick ukuhlukaniswa kombala wesikhumba ngezinhlobo I-VI ngokuya ngezici zokusabela kokusha noma ukushiswa kwesikhumba ngemva kokuchayeka elangeni:
Uhlobo I: Omhlophe; omhlophe kakhulu; izinwele ezibomvu noma ezimhloshana; amehlo aluhlaza okwesibhakabhaka; amabala
Uhlobo II: Okumhlophe; okukhanyayo; izinwele ezibomvu noma ezimhloshana, amehlo aluhlaza okwesibhakabhaka, aluhlaza okwesibhakabhaka, noma aluhlaza okwesibhakabhaka
Uhlobo III: Okumhlophe okukhilimu; okukhanyayo nanoma yimuphi umbala wamehlo noma wezinwele; kuvame kakhulu
Uhlobo IV: Onsundu; abantu baseMedithera abavamile, izinhlobo zesikhumba saseNdiya/sase-Asia
Uhlobo V: Izinhlobo zesikhumba ezinsundu kakhulu, eziphakathi nendawo
Uhlobo VI: Omnyama
Ngokuvamile kukholelwa ukuthi abantu baseYurophu nabaseMelika banokuqukethwe okuncane kwe-melanin esikhumbeni esiyisisekelo, futhi isikhumba singesohlobo I nolwesi-II; isikhumba esiphuzi eNingizimu-mpumalanga ye-Asia siwuhlobo III, IV, kanti okuqukethwe kwe-melanin esikhumbeni esiyisisekelo kuphakathi; isikhumba esinsundu-esimnyama sase-Afrika siwuhlobo V, VI, kanti okuqukethwe kwe-melanin esikhumbeni esiyisisekelo kuphezulu kakhulu.
Ngokwelashwa nge-laser yesikhumba kanye ne-photon, i-chromophore eqondiwe yi-melanin, futhi imishini kanye nemingcele yokwelashwa kufanele kukhethwe ngokuya ngohlobo lwesikhumba.
Uhlobo lwesikhumba luyisisekelo esibalulekile semfundiso yenkolo se-algorithmisihlaziyi sesikhumbaNgokwethiyori, abantu abanemibala yesikhumba ehlukene badinga ukusebenzisa ama-algorithm ahlukene lapho bebona inkinga yokushintsha umbala, okungasusa umehluko emiphumeleni ebangelwa imibala yesikhumba ehlukene ngangokunokwenzeka.
Kodwa-ke, okwamanjeumshini wokuhlaziya isikhumba sobusoemakethe banezinkinga ezithile zobuchwepheshe zokuthola isikhumba esimnyama nesinsundu, ngoba ukukhanya kwe-UV okusetshenziselwa ukuthola umbala cishe kumuncwa ngokuphelele yi-eumelanin ebusweni besikhumba. Ngaphandle kokubonakaliswa,isihlaziyi sesikhumbaayikwazi ukubamba amaza okukhanya abonakalayo, ngakho-ke ayikwazi ukubona ukushintsha kombala wesikhumba.
