Njengobuchwepheshe bokuhlola okubonakalayo, ubuchwepheshe bokulinganisa isithombe budinga ukubona ukukalwa kobuningi.Ukunemba kokulinganisa bekulokhu kuyinkomba ebalulekile elandelwa yilobu buchwepheshe.Amasistimu okulinganisa isithombe ngokuvamile asebenzisa izinzwa zesithombe njengama-CCDs ukuze athole ulwazi lwesithombe, aziguqule zibe amasignali edijithali futhi aziqoqele kukhompuyutha, bese esebenzisa ubuchwepheshe bokucubungula izithombe ukucubungula amasignali ezithombe zedijithali ukuze kutholwe izithombe ezihlukahlukene ezidingekayo.Ukubalwa kosayizi, ukwakheka namaphutha okuma kufinyelelwa ngokusebenzisa amasu okulinganisa ukuguqula ulwazi losayizi wesithombe ohlelweni lokudidiyela isithombe lube ulwazi losayizi wangempela.
Eminyakeni yamuva, ngenxa yokuthuthukiswa okusheshayo kwamandla okukhiqiza izimboni kanye nokuthuthukiswa kobuchwepheshe bokucubungula, kuvele inani elikhulu lemikhiqizo yobukhulu obubili obukhulu, okungukuthi ubukhulu obukhulu kanye nobukhulu obuncane.Isibonelo, ukulinganisa ubukhulu bangaphandle bendiza, ukulinganisa izingxenye ezibalulekile zemishini emikhulu, ukulinganisa kwe-EMU.Isilinganiso esibalulekile sobukhulu bezingxenye ezincane Umkhuba obheke ekwenziweni okuncane kwamadivayisi ahlukahlukene, ukukalwa kobukhulu obubalulekile ku-microelectronics kanye ne-biotechnology, njll., konke kuletha imisebenzi emisha yokuhlola ubuchwepheshe.Ubuchwepheshe bokulinganisa isithombe bunobubanzi obubanzi bokulinganisa.Kunzima kakhulu ukusebenzisa izilinganiso zemishini zendabuko ezikalini ezinkulu nezincane.Ubuchwepheshe bokulinganisa isithombe bungakhiqiza ingxenye ethile yento elinganisiwe ngokuya ngezidingo zokunemba.Hlehlisa noma hlehlisa ukuze ufeze imisebenzi yokulinganisa engenzeki ngezilinganiso zokusebenzisa imishini.Ngakho-ke, kungakhathaliseki ukuthi ukulinganisa usayizi omkhulu noma ukulinganisa okuncane, indima ebalulekile yobuchwepheshe bokulinganisa isithombe isobala.
Ngokuvamile, sibhekisela ezingxenyeni ezinosayizi osuka ku-0.1mm kuya ku-10mm njengezingxenye ezincane, futhi lezi zingxenye zichazwa ngamazwe ngamazwe njengezingxenye ze-mesoscale.Izidingo zokunemba zalezi zingxenye ziphakeme kakhulu, ngokuvamile zisezingeni le-micron, futhi isakhiwo siyinkimbinkimbi, futhi izindlela zokuthola ezivamile zinzima ukuhlangabezana nezidingo zokulinganisa.Amasistimu wokulinganisa izithombe abe yindlela evamile ekukalweni kwezingxenye ezincane.Okokuqala, kufanele senze isithombe sengxenye engaphansi kokuhlolwa (noma izici ezibalulekile zengxenye engaphansi kokuhlolwa) sisebenzisa ilensi yokubona enokukhulisa okwanele kwenzwa yesithombe esifanayo.Thola isithombe esiqukethe ulwazi lwethagethi yokulinganisa ehlangabezana nezimfuneko, bese uqoqa isithombe kukhompuyutha ngekhadi lokutholwa kwesithombe, bese wenza ukucubungula isithombe nokubala ngekhompyutha ukuze uthole umphumela wokulinganisa.
Ubuchwepheshe bokulinganisa isithombe emkhakheni wezingxenye ezincane ngokuyinhloko bunalezi zindlela zokuthuthuka ezilandelayo: 1. Ukuthuthukisa ngokwengeziwe ukunemba kokulinganisa.Ngokuthuthukiswa okuqhubekayo kwezinga lezimboni, izidingo zokunemba zezingxenye ezincane zizothuthukiswa nakakhulu, ngaleyo ndlela kuthuthukiswe ukunemba kokulinganisa ukunemba kobuchwepheshe bokulinganisa izithombe.Ngesikhathi esifanayo, ngokuthuthukiswa okusheshayo kwamadivayisi wezinzwa zesithombe, amadivaysi aphezulu aphezulu abuye enze izimo zokuthuthukisa ukunemba kwesistimu.Ukwengeza, ucwaningo olwengeziwe kubuchwepheshe be-sub-pixel kanye nobuchwepheshe bokulungiswa okuphezulu kuzohlinzeka ngosekelo lobuchwepheshe lokuthuthukisa ukunemba kwesistimu.
2. Thuthukisa ukulinganisa ukusebenza kahle.Ukusetshenziswa kwezingxenye ezincane embonini kukhula ezingeni lejometri, imisebenzi yokulinganisa esindayo ye-100% yokulinganisa emgqeni kanye namamodeli okukhiqiza adinga ukulinganisa okuphumelelayo.Ngokuthuthukiswa kwamakhono ezingxenyekazi zekhompuyutha kanye nokuthuthukiswa okuqhubekayo kwama-algorithms okucubungula izithombe, ukusebenza kahle kwamasistimu amathuluzi okulinganisa izithombe kuzothuthukiswa.
3. Qaphela ukuguqulwa kwengxenye encane ukusuka kumodi yokulinganisa iphuzu ukuya kumodi yokulinganisa iyonke.Ubuchwepheshe obukhona bensimbi yokulinganisa isithombe bukhawulelwe ukunemba kokulinganisa, futhi ngokuyisisekelo isithombe sifanekisela indawo yesici esiyinhloko engxenyeni encane, ukuze kuqashelwe ukukalwa kwephoyinti lesici esiyinhloko, futhi kunzima ukukala yonke ikhontoyutha noma sonke isici. iphuzu.
Ngokuthuthukiswa kokunemba kokulinganisa, ukuthola isithombe esiphelele sengxenye kanye nokuzuza ukukalwa okunembayo okuphezulu kwephutha lomumo lilonke kuzosetshenziswa emikhakheni eminingi.
Ngamafuphi, emkhakheni wokulinganisa ingxenye encane, ukusebenza kahle okuphezulu kobuchwepheshe bokulinganisa isithombe obunembayo nakanjani kuzoba inkomba ebalulekile yokuthuthukiswa kobuchwepheshe bokulinganisa ukunemba.Ngakho-ke, isistimu yezingxenyekazi zekhompuyutha yokutholwa kwesithombe ithole izidingo eziphakeme zekhwalithi yesithombe, ukuma konqenqema lwesithombe, ukulinganiswa kwesistimu, njll., futhi inamathuba abanzi okusebenza kanye nokubaluleka kocwaningo olubalulekile.Ngakho-ke, lobu buchwepheshe sebuphenduke indawo yokucwaninga ekhaya nakwamanye amazwe, futhi sebungenye yezinhlelo zokusebenza ezibaluleke kakhulu kubuchwepheshe bokuhlola okubukwayo.
