imininingwane yokusebenzisa isithwebuli sebhakhodi

khetha uhlobo olufanele lokuskena lweskena sebhakhodi

Ukukhetha uhlobo olufanele lokuskena ngeke kusize nje kuphela ukuthuthukisa izinga lempumelelo yokubonwa kwesikena, kodwa futhi kukhiqize usayizi ofanele wefayela. Ngokuvamile, izikena zinganikeza abasebenzisi izinhlobo ezintathu zokuskena: isithombe, okumpunga nokumnyama nokumhlophe. Ngaphambi kokuskena, kufanele sikhethe uhlobo lokuskena olulungile ngokwezinto ezihlukile zokuskena" "Isithombe" uhlobo lokuskena lulungele ukuskena izithombe zombala. Idinga isampula yamazinga amaningi kanye nokugcinwa kwamashaneli abomvu, aluhlaza okwesibhakabhaka, azokhiqiza amafayela osayizi abakhulu Uhlobo lokuskena lucabangela kokubili umbhalo nezithombe ezinamaleveli amaningi ampunga, futhi usayizi wefayela umaphakathi“ Uhlobo lokuskena "olumnyama nomhlophe" luvame ukusetshenziswa ekuskeneni kombhalo wesandla omnyama nomhlophe. Uma uskena ngalolu hlobo, iskena sizomela amaphikseli amnyama namhlophe ngebhithi elilodwa, futhi usayizi wefayela owenziwe ngale ndlela mncane kakhulu.

skena umbhalo wesandla ngendlela efanele

Namuhla, ukuze ugweme inkinga yokufaka isiShayina. izinhlamvu, abantu abaningi baqala ukusebenzisa isithwebuli sebhakhodi ukufaka imibhalo yesandla; Ukuze siqinisekise ukuthi isithwebuli sinezinga eliphezulu lokuqashelwa, kufanele siqinisekise ukuthi umbhalo wesandla oskeniwe ucacile. Ngaphansi kwezimo ezifanayo, izinga lokuqashelwa kombhalo wesandla ovamile ophrintiwe nombhalo wesandla ophrintiwe ungafinyelela ngaphezu kwama-95%; Kodwa-ke, isoftware eminingi ye-OCR ayinalo izinga eliphezulu lokuqashelwa kwama-athikili angacacile njengamakhophi namaphephandaba. Uma abasebenzisi badinga ukuskena imibhalo yesandla ewugqinsi, uma beyiskena ngokuqondile, akunakugwemeka ukuthi omunye umbhalo ngeke ucace futhi uhlanekezelwe ngenxa yokusatshalaliswa okungaphelele kombhalo. Ngenxa yalokho, isofthiwe ye-OCR ayikwazi ukubona umbhalo ngendlela efanele, okwehlisa kakhulu izinga lokuqashelwa. Ngakho-ke, ngaphambi kokuskena, kungcono uhlukanise umbhalo ube ikhasi elilodwa, bese uwuskena. Ephephandabeni elijwayelekile, ngoba lisesimweni seshidi elilodwa, ayikho inkinga enjalo. Nokho, ngenxa yokuthi indawo yephephandaba ngokuvamile inkulu, ayikwazi ukuskenwa ngesikhathi esisodwa. Ngakho-ke, uma kuqala ukuskena, khetha ububanzi bokuskena kuqala bese uskena indawo eyodwa ngesikhathi, ukuze umphumela wokubonwa uthuthuke kakhulu.

Lungisa ukukhanya nokugqama

Ukuze uthole umphumela wokuskena wesithombe ophezulu, kufanele ifunde ukulungisa ukukhanya nokugqama. Isibonelo, uma ukukhanya kwesikali esimpunga nezithombe zombala kukhanya kakhulu noma kumnyama kakhulu, ungashintsha ukukhanya ngokuhudula isilayidi kusilayida sokukhanya. Uma ukukhanya kuphezulu kakhulu, isithombe sizobukeka simhlophe; Uma ukukhanya kuphansi kakhulu, kumnyama kakhulu. Uma uhudula isilayidi sokukhanya, yenza ukukhanya kwesithombe kulinganisele. Ngokufanayo, kwamanye amapharamitha, singenza ukuguqulwa kwendawo ngendlela efanayo yokulungisa kuze kuneliseke umphumela wethu wokubuka.

umbala wokuskena olungile

Ukuze senze izithombe ezimibalabala zithole ukwethembeka okuphezulu, kufanele silungise inombolo yemibala yokuskena ngaphambi kwesithwebuli. Lapho ulungisa, qala ngokukhetha inombolo encane yombala yesithwebuli sebhakhodi, uskene isithombe sombala esinqunywe kusengaphambili, bese usetha imodi yokubonisa yesibonisi kumbala wangempela. Qhathanisa nowokuqala, bheka ukuthi umbala ugcwele yini nokuthi kukhona ukuchezuka kombala. Kufanele kuqashelwe ukuthi asikho isimo sokungaguquguquki okuphelele nokwasekuqaleni, isibonisi singase sikhiqize ukuchezuka kombala, okungase kuthinte ukubhekwa, futhi uhlelo lwe-photosensitive lweskena lungase lukhiqize ukuchezuka okuthile kombala. Izikena eziningi ezisezingeni eliphezulu nezikena ezisezingeni eliphakathi zifakwe isofthiwe yokulungisa umbala, kodwa izikena ezimbalwa kuphela ezisezingeni eliphansi ezifakwe isofthiwe yokulungisa imibala. Sicela ulinganise umbala wesibonisi nesikena ngaphambi kokuhlola.
