Kuzindikira Khalidwe la Odziwika (OCR) limatanthawuza mapulogalamu omwe amapanga ma digito, osindikizidwa kapena olembedwa pamanja omwe makompyuta amatha kuwerenga popanda kufunika kuti azilemba kapena kulemba. OCR imagwiritsidwa ntchito pamapepala osinthidwa papepala , koma ikhoza kukhazikitsanso makalata owerengedwa ndi makompyuta mu fayilo ya fano.
Kodi OCR ndi chiyani?
OCR, yomwe imatchulidwanso kuti ndizovomerezeka, ndi mapulogalamu a mapulogalamu omwe amasintha anthu monga ziwerengero, malembo, ndi zilembo zamatchulidwe (zomwe zimatchedwanso glyphs) kuchokera pamapepala osindikizidwa kapena olembedwa mu mawonekedwe apakompyuta omwe amadziwika mosavuta komanso amawerengedwa ndi makompyuta ndi mapulogalamu ena a mapulogalamu. Mapulogalamu ena a OCR amachita izi ngati chikalata chikujambulidwa kapena kujambulidwa ndi kamera ya digito ndi ena akhoza kugwiritsa ntchito njirayi kuti afotokoze zomwe zalembedwa kale kapena kujambulidwa popanda OCR. OCR imalola ogwiritsa ntchito kufufuza mu mapepala a PDF, kusindikiza malemba, ndi kukonzanso mafomu.
Kodi OCR ndi Yotani?
Mwachangu, zosowa za tsiku ndi tsiku, OCR sangakhale yaikulu. Ngati mutapanga kuchuluka kwa kusanthula, kukwanitsa kufufuza mkati mwa PDF kuti mupeze zomwe mukufunikira kungasungitse nthawi ndithu ndikupanga OCR ntchito yanu pulojekiti yanu yofunikira kwambiri. Nazi zina mwazinthu zomwe OCR zimathandizira ndi:
- Kukonzekera kwa deta komanso kusalowa kwa deta
- Kupanga mabuku ojambulidwa amafufuzidwa
- Kutembenuza zolemba zolembedwa pamakalata owerengedwa ndi makompyuta
- Kupanga zolemba zambiri zomwe zimagwiritsidwa ntchito ndi mapulogalamu owerenga omwe amathandiza ogwiritsira ntchito osokonezeka
- Kusungira zikalata zamakedzana ndi nyuzipepala, komanso kuzipanga kufufuza
- Kuchokera kwa deta ndikuyendetsa mapulogalamu owerengetsera ndalama (Chitsanzo: Malipiro ndi mavoti)
- Zolembera zolemba zomwe zingagwiritsidwe ntchito ndi injini zosaka
- Kuzindikiritsa mapulogalamu a dalaivala ndi kamera yothamanga ndi pulogalamu ya kamera yofiira
- Kulankhulana kwa anthu omwe satha kulankhula - filosofi wamaphunziro a sayansi, Stephen Hawking, mwinamwake ndi wodziwa bwino kwambiri pulogalamu ya synthesizer yolankhula
N'chifukwa Chiyani Mukugwiritsa Ntchito OCR?
Bwanji osangotenga chithunzi, chabwino? Chifukwa simungathe kusintha chirichonse kapena kufufuza malemba chifukwa chingakhale chithunzi. Kusinthanitsa pepala ndi kutsegula mapulogalamu a OCR kungasinthe fayiloyo ku chinachake chimene mungathe kusintha ndikukhoza kufufuza.
Mbiri ya OCR
Ngakhale kuti kalembedwe kake kanali koyamba chaka cha 1914, kufalikira kwakukulu ndi kugwiritsa ntchito njira zamakono zogwirizana ndi OCR zinayambira mwakhama m'ma 1950, makamaka polemba zilembo zophweka zomwe zinali zosavuta kusintha kuti zikhale zowerengeka. Yoyamba ya ma fonti ophwekawo inalengedwa ndi David Shepard ndipo ambiri amadziwika kuti OCR-7B. OCR-7B ikugwiritsidwanso ntchito masiku ano m'makampani azachuma omwe amagwiritsa ntchito makadi a ngongole ndi makadi a debit. M'zaka za m'ma 1960, mautumiki m'mayiko angapo anayamba kugwiritsa ntchito zipangizo zamakono kuti azithamangitsa makalata, kuphatikizapo United States, Great Britain, Canada, ndi Germany. OCR akadali teknolojia yamakono yogwiritsira ntchito makalata opita ku positi padziko lonse lapansi. Mu 2000, chidziwitso chachikulu cha malire ndi luso la teknoloji ya OCR chinagwiritsidwa ntchito popanga mapulogalamu a CAPTCHA omwe amaletsa kuyimitsa mabomba ndi spammers.
Kwa zaka zambiri, OCR yakula bwino kwambiri komanso yopambana kwambiri chifukwa cha kupita patsogolo kwa zipangizo zamakono monga nzeru zamakono , kuphunzira makina , ndi ma kompyuta. Masiku ano, mapulogalamu a OCR amagwiritsa ntchito maonekedwe, mawonekedwe, komanso malemba kuti asinthe malemba mofulumira komanso molondola kuposa kale lonse.
