I-Optical Character Recognition (OCR) ibhekisela kwisofthiwe edala idijithali yoshicilelo eprintiweyo, eprintiweyo okanye ebhalwe ngesandla apho iikhomputha zikwazi ukufunda ngaphandle kwidingo yokubhala ngesandla okanye ukufaka umbhalo. I-OCR isetyenziswa ngokubanzi kumaxwebhu afundwayo kwifomati yePD , kodwa inokudala i-computer efundekayo yombhalo ngaphakathi kwifayile yesithombe.
Yintoni i-OCR?
I-OCR, ekwabizwa ngokuba yi-text recognition, iteknoloji yesofthiwe eguqula abalinganiswa njengamanani, iileta kunye neziphumlisi (ezibizwa ngokuba yi-glyphs) ezivela kumaphepha abhaliweyo okanye abhaliweyo kwifomu yekhompyutheni eyaziwa ngokulula kwaye ifundwe yiikhomputha kunye nezinye iinkqubo zesoftware. Ezinye iiprogram ze-OCR zenza oku njengoko uxwebhu luchithwa okanye lufotshwa ngekhamera yedijithali kunye nabanye banokufaka le nkqubo kwiimpepha ezifunyenwe ngaphambili okanye zifotwe ngaphandle kwe-OCR. I-OCR ivumela abasebenzisi ukukhangela ngaphakathi kwamaxwebhu e-PDF, ukuhlela umbhalo, nokufometha amaphepha.
Yintoni i-OCR esetyenzisiweyo?
Ngokukhawuleza, zonke iintswelo zokuskena iintsuku, i-OCR ingabi yinto enkulu. Ukuba wenza inani elikhulu lokuskena, ukukwazi ukucinga ngaphakathi kwe-PDF ukufumana oluchanekileyo olufunekayo lingagcina ixesha elithile kwaye kwenza umsebenzi we-OCR kwiprogram yakho yokubhaliweyo ibaluleke ngakumbi. Nazi ezinye izinto i-OCR inceda nge:
- Ukucwangciswa kwedatha ngokuzenzekelayo kunye nokungena kwedatha (Umzekelo: Iinkqubo zokulandelela izithuba zabasebenzi bokuqalisa umsebenzi)
- Ukwenza iincwadi ezinokukhangela
- Ukuguqula izikrini ezibhalwe ngesandla ngesandla kwisicatshulwa esifundekayo
- Ukwenza amaxwebhu asebenziseke ngakumbi ngeenkqubo zokufunda ezibanceda abasebenzisi abangabonakaliyo
- Ukugcinwa kwamaxwebhu embali kunye namaphephandaba, ngelixa libenza benze uphenyo
- Idatha yokukhutshwa kunye nokudluliselwa kwiiprogram zokubhala (Umzekelo: Iimbuyekezo kunye neenvoyisi)
- Iimpawu ezibonisa ukusetyenziswa kweenjini zokukhangela
- Ukuqwalaselwa kweelayisenisi zokuqhuba ilayisenisi ngekhamera yekhawulezi kunye nesofthiwe yekhamera ekhanyayo
- Intetho zokwenza izinto zokwenza izinto kubantu abangakwazi ukuthetha - i-physicist theory, uStephen Hawking, mhlawumbi ngumsebenzisi owaziwayo kakhulu kwinkqubo yokuthetha intetho
Kutheni usebenzisa i-OCR?
Kutheni ungathathi nje isithombe, kunene? Ngenxa yokuba awukwazi ukuhlela nantoni na okanye uphendule itekisi kuba iya kuba ngumfanekiso. Ukutshintshwa kwenkqubo kunye nokusebenzisa i-OCR software kungenza le fayile ibe yinto onokuyihlela kwaye ukwazi ukuyikhangela.
Imbali ye-OCR
Ngethuba ukusetyenziswa kokuqala kokubhaliweyo kwimihla kufike ngo-1914, ukuphuhliswa kokubanzi kunye nokusetyenziswa kobuchwepheshe obunxulumene ne-OCR baqala ngokunyanisekileyo kuma-1950, ngokukodwa ngokudalwa kwamagama afanelekanga okuguquguqukayo ukuba aguqule ngokubhaliweyo. Iyokuqala yale mijelo elula yenziwe nguDavid Shepard kwaye eyaziwa ngokuba ngu-OCR-7B. I-OCR-7B isasetyenziswa namhlanje kwimboniselo yezemali kumgangatho oqhelekileyo osetyenzisiweyo kumakhadi-mboleko kunye namakhadi e-debit. Ngama-1960, iinkonzo zeposi kwiindawo ezininzi zaqala ukusebenzisa i-OCR iteknoloji ukukhawuleza ukukhawuleza ukuthumela iimeyile, kubandakanya iUnited States, Great Britain, Canada kunye neJamani. I-OCR isengundoqo yeteknoloji esetyenziselwa ukuhlenga iimeyile zeenkonzo zeposi kwihlabathi jikelele. Ngo-2000, ulwazi oluphambili lwemida kunye nobuchule be-teknoloji ye-OCR lwasetyenziselwa ukuphuhlisa iiprogram ze-CAPTCHA ezisetyenziselwa ukuyeka i-bots kunye ne-spammers.
Kule minyaka, i-OCR iye yanda ngokuchanekileyo kwaye iqhubekile ngakumbi ngenxa yokuqhubela phambili kwiinkalo zeteknoloji ezinxulumene neengcinga zobugcisa , ukufundwa komatshini kunye nomboniso wekhompyutha. Namhlanje, i-software ye-OCR isebenzisa ukuqaphela iprojekthi, ukufumanisa ukubonakala, kunye nokumbumbana kwembhalo ukuguqula amaxwebhu ngokukhawuleza nangokuchanekileyo kunanini ngaphambili.
