Ungasetha kanjani isithwebuli sebhakhodi ukuze uthole umphumela omuhle kakhulu?

Sisethwa kanjani isithwebuli sebhakhodi ukuze sizuze umphumela omuhle?

Kungani umphumela wokuskena weskena usanda kuthengwa ungemuhle, ikhwalithi yesithwebuli ayisihle, noma lapho isithwebuli sihluleka khona. Namuhla, ake sixoxe ngokusethwa kwesithwebuli sekhodi yebha nokuthi ungawufinyelela kanjani umphumela wokuskena ongcono kakhulu futhi uthuthukise ukusebenza kahle komsebenzi. Isamba samaphuzu ayisikhombisa afingqiwe kanje:

1. Thola indlela efanelekile yokuskena

Ukusebenzisa isithwebuli sekhodi yebha kungaskena izithombe, amagama nezithombe. Izinto zokuskena ezihlukene zinezindlela ezihlukene zokuskena. Vula isixhumi esibonakalayo somshayeli se-isikena sebhakhodi, futhi sithola ukuthi uhlelo luhlinzeka ngezinketho ezintathu zokuskena, phakathi kwazo imodi "emnyama-nomhlophe" isetshenziswa ekuqapheliseni kwangempela noma kwe-OCR kwezinhlamvu ezimhlophe nezimnyama; "Isikali esimpunga" sisebenza ekuhlelweni okuxubile kwezithombe namathekisthi anezithombe nemibhalo. Lolu hlobo lokuskena lucabangela kokubili imibhalo nezithombe ezinamaleveli amaningi ampunga; "Isithombe" sifanele ukuskena izithombe ezinemibala. Idinga ukuthatha isampula futhi igcine amashaneli amathathu okubomvu, okuluhlaza okwesibhakabhaka nokuluhlaza okwesibhakabhaka kumaleveli amaningi. Ngaphambi kokuskena, kufanele siqale sikhethe indlela yokuskena efanele ngokuya ngento eskeniwe, ukuze sithole umphumela wokuskena ophezulu.

2. Lungiselela ukulungiswa kwesibhamu sokuskena ibhakhodi

Uma ukulungiswa kokuskena kuphezulu, isithombe sizocaca kakhulu. Kodwa-ke, uma kucatshangelwa ukuthi uma ukulungiswa kwedivayisi okukhiphayo kudlulwa, kungakhathaliseki ukuthi isithombe singaphrintwa kucace kangakanani, sivele sithathe isikhala sediski esiningi futhi asinalo inani elisebenzayo. Ngakho-ke, kuyadingeka ukukhetha isinqumo esifanele sokuskena. Izithombe ezinkulu zingancishiswa ngemva kokuskena. Isibonelo, siskena isithombe esingu-4-bit esithombeni esingu-600dpi × 4-intshi. Yehlise ibe ngu-2 kuhlelo lomhlangano × 2 amayintshi, ukulungiswa kwayo kungu-1200 DPI.

3. Setha usayizi wefayela

Kungakhathaliseki ukuthi into eskeniwe ingumbhalo, isithombe noma isithombe, iyisithombe ngemva kokuphumayo ngeskena sekhodi yebha, futhi usayizi wesithombe uhlobene ngokuqondile nosayizi womthamo wefayela. Ngakho-ke, kufanele sibeke usayizi wefayela lapho siskena. Ngokuvamile, i-isikena sebhakhodi ingakwazi ukubala usayizi wefayela ngokuzenzakalelayo lapho uhlola kuqala isampula yokuqala, kodwa ukuqonda indlela yokubala yosayizi wefayela kusiza kakhulu ukuba wenze ukukhetha okufanele lapho ulawula amafayela askeniwe futhi unquma ukulungiswa kokuskena. Ifomula yokubala yefayela lesithombe kanambambili ithi: usayizi ovundlile × ubukhulu obuqondile × [2 (ukulungiswa kokuskena) / 8]. Ifomula yokubala yefayela lesithombe esinemibala ithi: usayizi ovundlile × ubukhulu obuqondile × [2 (ukulungiswa kokuskena) / 3].

4. Setha imingcele yokuskena

Uma uskena ngaphambilini izithombe, i-isikena sebhakhodi iskena ngokuya ngevelu yepharamitha yokuskena ezenzakalelayo yesistimu. Umphumela ungase uhluke ezintweni ezihlukene zokuskena nezindlela ezihlukene zokuskena. Ngakho-ke, ukuze sithole ikhwalithi ephezulu yokuskena isithombe, singakwazi ukulungisa amapharamitha mathupha. Isibonelo, uma ukukhanya kwesikali esimpunga nezithombe zombala kukhanya kakhulu noma kumnyama kakhulu, singashintsha ukukhanya ngokuhudula isilayidi kusilayida sokukhanya. Uma ukukhanya kuphezulu kakhulu, isithombe sizobukeka simhlophe; Uma ukukhanya kuphansi kakhulu, kumnyama kakhulu. Kufanele wenze ukukhanya kwesithombe kube okumaphakathi uma uhudula isilayidi sokukhanya. Ngokufanayo, kwamanye amapharamitha, singenza ukuguqulwa kwendawo ngokuya ngendlela efanayo yokulungisa kuze kube yilapho umphumela wethu wokubuka ugculisa. Ngamafuphi, isithombe esihle esiskeniwe kufanele sizame ukuhlangabezana nokuphumayo kokuphrinta ngaphandle kokulungiswa okwengeziwe ngesofthiwe yokucubungula izithombe, futhi sisondele kakhulu kwikhwalithi yokuphrinta.

5. Gcina ijika bese ulayisha isofthiwe yokuskena

Ngezinye izikhathi, ukuze uthole umbala ongcono kakhulu nokugqama kokuskena, siqale senze ukuskena okunesinqumo esiphansi, sikuvule ku-Photoshop, bese sisebenzisa umsebenzi wejika we-Photoshop ukuthuthukisa umbala nokugqama. . Gcina ijika bese ulilayisha futhi ku-software yokuskena. Iskena sakho sebhakhodi manje sizosebenzisa le jika yokulungisa umbala ukuze sakhe amafayela angcono anokulungiswa okuphezulu. Uma uskena izithombe ezimbalwa ngobubanzi be-gamut obufanayo, ungasebenzisa amajika afanayo, futhi ungakwazi ngokuvamile ukugcina amajika bese uwalayisha futhi njengoba kudingeka.

6. Beka into eskeniwe ngokomphumela oyifunayo

Enqubeni yokusebenzisa izithombe, kwesinye isikhathi siyethemba ukuthola izithombe ezinomphumela wokutsheka. Abaklami abaningi bavame ukufaka izithombe kukhompuyutha ngesithwebuli sekhodi yebha, bese besebenzisa isofthiwe yezithombe ezichwepheshile ukuze bazungezisa izithombe ukuze bazuze umphumela wokuzungezisa. Nokho, le nqubo iwukumosha isikhathi. Ngokusho kwe-engeli yokuzungezisa, Ikhwalithi yesithombe izokwehla. Uma sazi ukuthi isithombe sibekwe kanjani ekhasini kusengaphambili, lapho-ke ukusebenzisa i-protractor kanye nonqenqema olungezansi lwesoqobo ukubeka esangempela kurola kanye neplathifomu nge-engeli enembile kuzothola isithombe sekhwalithi ephezulu ngaphandle kokuzungezisa ekucubungulweni kwesithombe. isofthiwe.
