Yintoni iteknoloji ye-OCR?
I-Optical Character Recognition (isiNgesi: i-Optical Character Recognition, i-OCR) ibhekisela kwinkqubo yokuhlalutya kunye nokuqaphela iifayile zemifanekiso yezinto ezibhaliweyo ukufumana isicatshulwa kunye nolwazi loyilo.
Ngokufana nokuqaphela umfanekiso kunye nobuchwepheshe bombono womatshini, inkqubo yokucubungula iteknoloji ye-OCR iphinde yahlulwe ibe yigalelo, ukucubungula kwangaphambili, ukuqhutyelwa phambili kwexesha eliphakathi, ukusetyenzwa emva kunye nenkqubo yokuphuma.
ngena
Kwiifomathi zemifanekiso eyahlukeneyo, kukho iifomathi ezahlukeneyo zokugcina kunye neendlela ezahlukeneyo zokucinezela.Okwangoku, kukho i-OpenCV, i-CxImage, njl.
Ukulungiswa kwangaphambili - ukuguqulwa kwebhinari
Uninzi lwemifanekiso ethathwe ziikhamera zedijithali namhlanje ziyimifanekiso yemibala, equlethe ulwazi oluninzi kwaye ayifanelekanga iteknoloji ye-OCR.
Ngomxholo womfanekiso, sinokuwuhlula ngokulula ube ngumphambili kunye nemvelaphi.Ukuze wenze ikhomputha ngokukhawuleza kwaye isebenze ngcono izibalo ezinxulumene ne-OCR, kufuneka siqhube umfanekiso wombala kuqala, ukuze kuphela ulwazi lwangaphambili kunye nolwazi lwangasemva luhlala emfanekisweni.I-Binarization inokuqondwa ngokulula njenge "mnyama namhlophe".
ukunciphisa ingxolo yomfanekiso
Kwimifanekiso eyahlukeneyo, inkcazo yengxolo inokuthi ihluke, kwaye inkqubo yokukhupha i-denoising ngokweempawu zengxolo ibizwa ngokuba kukunciphisa ingxolo.
ukulungiswa kwethambeka
Ngenxa yokuba abasebenzisi abaqhelekileyo, xa bethatha imifanekiso yamaxwebhu, kunzima ukudubula ngokupheleleyo ngokuhambelana nolungelelwaniso oluthe tyaba kunye noluthe nkqo, ngoko ke imifanekiso ethathiweyo iya kuphoswa ngokuqinisekileyo, efuna isoftware yokulungisa umfanekiso.
Ukusetyenzwa kwexesha eliphakathi – uhlalutyo loyilo
Inkqubo yokwahlula-hlula imifanekiso yamaxwebhu ngokwemihlathi namasebe ibizwa ngokuba yi-layout analysis.Ngenxa yeyantlukwano kunye nobunzima bamaxwebhu okwenene, eli nyathelo lisafuna ukuphuculwa.
ukusika umlinganiswa
Ngenxa yokuthintelwa kweemeko zokufota kunye nokubhala, abalinganiswa bahlala bebambekile kwaye iipeni zophuka.Ukusebenzisa ngokuthe ngqo imifanekiso enjalo kuhlalutyo lwe-OCR kuya kukunciphisa kakhulu ukusebenza kwe-OCR.Ke ngoko, ukwahlulahlula abalinganiswa kuyafuneka, oko kukuthi, ukwahlula abalinganiswa abahlukeneyo.
Ukuqaphela umlinganiswa
Kwinqanaba lokuqala, ukuthelekisa itemplate kwakusetyenziswa kakhulu, kwaye kwinqanaba lamva, ukutsalwa kweempawu kwakusetyenziswa ikakhulu.Ngenxa yempembelelo yezinto ezifana nokuchithwa kwesicatshulwa, ubukhulu be-stroke, ipeni eyaphukileyo, i-adhesion, ukujikeleza, njl., ubunzima be-extract extraction buchaphazeleka kakhulu.
Ukubuyiselwa koyilo
Abantu banethemba lokuba isicatshulwa esamkelweyo sisacwangciswa njengomfanekiso woxwebhu lwentsusa, kwaye imihlathi, izikhundla, kunye nocwangco ziphuma kumaxwebhu eWord, amaxwebhu ePDF, njalo njalo, kwaye le nkqubo ibizwa ngokuba yi-layout restoration.
ukusetyenzwa kweposi
Ngokobudlelwane bomxholo wolwimi oluthile, isiphumo sokuqaphela siyalungiswa.
imveliso
Imveliso yoonobumba abaziwayo njengombhalo kwifomati ethile.
Zeziphi usetyenziso lweetheminali eziphathwa ngesandla ezisekwe kubuchwephesha be-OCR?
Ngokusebenzisa i-terminal ephathwayo yePDA elayishwe nge-software ye-OCR yokuqaphela umlinganiswa, izicelo ezininzi zomboniso zinokuqondwa, ezinje: ukuqondwa kwepleyiti yelayisenisi yemoto, ukuqondwa kwenombolo yesikhongozeli, ukuqondwa kweleyibhile yenkomo kunye nobunzima begusha, ukuqondwa kwendawo efundeka ngomatshini wokundwendwela, ukuqondwa kokufundwa kwemitha yombane. , Ikhoyili yensimbi Ukuqaphela iimpawu ezitshiziweyo.
