Euskal OCR C# eta .NET-en

Updated: 2026년 6월 29일

Dokumentu honen beste bertsio batzuk:

IronOCR C# softwarearen osagaia da .NET kodetzaileek 126 hizkuntzatako irudien eta PDF dokumentuen testua irakurtzea 126 hizkuntzatan, euskara barne.

Tesseract-en sardexka aurreratua da, .NET garatzaileentzat soilik eraikia eta aldian-aldian beste Tesseract motorrak gainditzen ditu abiadura eta zehaztasunagatik.

Zergatik aukeratu IronOCR?

IronOCR .NET software liburutegia instalatzen erraza, osoa eta ondo dokumentatuta dago.

Aukeratu IronOCR % 99,8 + OCR zehaztasuna lortzeko kanpoko web zerbitzurik, etengabeko tasarik edo Internet bidez isilpeko dokumentuak bidali gabe.

Zergatik aukeratzen dute C# garatzaileek IronOCR Vanilla Tesseract baino?

Instalatu DLL edo NuGet bakar gisa
Tesseract 5, 4 eta 3 motorretarako sartzen da kutxatik kanpora.
Zehaztasunak % 99,8k ohiko Tesseract gainditzen du.
Blazing Speed eta MultiThreading
MVC, WebApp, Desktop, Console & Server Application bateragarriak dira
Ez dago Exes edo C ++ koderik lan egiteko
PDF OCR laguntza osoa
OCR ia edozein irudi fitxategi edo PDF egiteko
.NET Core, Standard eta FrameWork euskarri osoa
Inplementatu Windows, Mac, Linux, Azure, Docker, Lambda, AWS zerbitzuetan

Multithreading euskarria
Nazioarteko 126 hizkuntza guztiak NuGet edo OcrData fitxategien bidez kudeatuak
Atera irudiak, koordenatuak, estatistikak eta letra tipoak. Ez bakarrik testua.
Tesseract OCR birbanatzeko aplikazio komertzial eta jabedunen barruan banatzeko erabil daiteke.

Burdinazko OCR distirak distira ematen du mundu errealeko irudiekin eta dokumentu inperfektuekin lan egitean, hala nola argazkiekin edo bereizmen txikiko eskanerrak, zarata digitala edo akatsak izan ditzaketenak.

.NET plataformarako doako beste OCR liburutegi batzuek .NET Tesseract APIak eta web zerbitzuek ez dute hain ondo funtzionatzen mundu errealeko erabilera kasu hauetan.

OCR Tesseract 5-rekin - Hasi kodeketa C#-ean

Beheko kode laginak erakusten du zein erraza den C# edo VB .NET erabiliz irudi bateko testua irakurtzea.

OCR irudiak hobetzeko iragazkiak

IronOCR-k OcrInput objektuentzako iragazki bakarrak eskaintzen ditu OCR errendimendua hobetzeko.

Irudia hobetzeko kodearen adibidea

OCR irudi iragazkien zerrenda

IronOCR programan integratutako OCR errendimendua hobetzeko sarrera iragazkiak hauek dira:

OcrInput.Rotate(degrees double) - Irudiak erlojuaren norabidean biratzen ditu. Erlojuaren aurkako norabidean, erabili zenbaki negatiboak.
OcrInput.Binarize() - Irudi-iragazki honek pixel guztiak beltz edo zuri bihurtzen ditu bide ertainik gabe. Testuaren atzeko planoarekiko kontraste oso baxuko OCR errendimendu kasuak hobe ditzake.
OcrInput.ToGrayScale() - Irudi-iragazki honek pixel bakoitza gris- tonuko tonu bihurtzen du. Nekez hobetuko du OCR zehaztasuna, baina abiadura hobe dezake
OcrInput.Contrast() - Kontrastea automatikoki handitzen du. Iragazki honek askotan OCR abiadura eta zehaztasuna hobetzen ditu kontraste baxuko miaketetan.
OcrInput.DeNoise() - Zarata digitala kentzen du. Iragazki hau zarata espero den tokian soilik erabili behar da.
OcrInput.Invert() - Kolore guztiak alderantzikatzen ditu. Adibidez, zuria beltz bihurtzen da: beltza zuri bihurtzen da.
OcrInput.Dilate() - Morfologia aurreratua. Dilatazioak pixelak gehitzen ditu irudi bateko objektuen mugetan. Erodearen aurkakoa
OcrInput.Erode() - Morfologia aurreratua. Higadurak objektuen mugetan pixelak kentzen ditu Dilate of Opposite
OcrInput.Deskew() - Irudi bat biratzen du, beraz, modu egokian gora eta ortogonala da. Hau oso erabilgarria da OCRrako, Tesseract-en tolerantzia okerreko miaketetan 5 gradu artekoa izan baitaiteke.
OcrInput.DeepCleanBackgroundNoise() - Atzeko planoko zarata kentzea. Erabili iragazki hau soilik dokumentu muturreko atzeko zarata ezagutzen bada, iragazki honek dokumentu garbien OCR zehaztasuna murrizteko arriskua izango duelako eta CPU oso garestia delako.
OcrInput.EnhanceResolution - Kalitate baxuko irudien bereizmena hobetzen du. Iragazki hau ez da askotan behar OcrInput.MinimumDPI eta OcrInput.TargetDPI bereizmen txikiko sarrerak automatikoki harrapatu eta ebatziko dituztelako .

GarbiketaHondoa. Hau denbora gutxi behar duen ezarpena da; hala ere, liburutegiak irudi digital baten barruan zarata digitala, papera xehatu eta bestelako akatsak automatikoki garbitzeko aukera ematen du, bestela beste OCR liburutegi batzuek irakurtzeko gaitasuna izango lukete.

EnhanceContrast IronOCR-k testuaren kontrastea irudi baten atzeko aldean automatikoki handitzen duen ezarpena da, OCRren zehaztasuna handituz eta, oro har, errendimendua eta OCR abiadura handituz.

EnhanceResolution bereizmen txikiko irudiak (275 dpi baino gutxiagokoak) automatikoki detektatuko dituen ezarpena da eta automatikoki irudia handitu eta testu guztia zorroztuko du, OCR liburutegi batek irakurri ahal izateko. Eragiketa honek berez denbora asko eskatzen duen arren, orokorrean irudi batean OCR eragiketa egiteko denbora orokorra murrizten du.

Language IronOCR-k nazioarteko 22 hizkuntza-pakete onartzen ditu eta hizkuntza-ezarpena OCR eragiketa batean aplikatu beharreko hizkuntza bat edo gehiago hautatzeko erabil daiteke.

Strategy IronOCR-k bi estrategia onartzen ditu. Aukeratu dezakegu dokumentu baten eskaneatze azkarra eta hain zehatza ez egitea edo adimen artifizialeko eredu batzuk erabiltzen dituen estrategia aurreratua erabiltzea OCR testuaren zehaztasuna automatikoki hobetzeko esaldi bateko hitzek elkarren artean duten erlazio estatistikoa aztertuz. .

ColorSpace ezarpena da, grisen eskalan edo koloretan OCR aukeratu ahal izateko. Oro har, grisen eskala da aukerarik onena. Hala ere, zenbaitetan antzeko tonua duten baina oso kolore desberdineko testuak edo atzeko planoak daudenean, kolore osoko espazio batek emaitza hobeak emango ditu.

DetectWhiteTextOnDarkBackgrounds. Oro har, OCR liburutegi guztiek testu beltza atzealde zurietan ikustea espero dute. Ezarpen horri esker, IronOCR-k testu zuridun negatiboak edo orrialde ilunak automatikoki detektatu eta irakurri ditzake.

InputImageType. Ezarpen horri esker, garatzaileak OCR liburutegia gidatu dezake dokumentu osoa edo zatitxo bat aztertzen ari den, pantaila-argazkia adibidez.

RotateAndStraighten ezarpen aurreratua da eta Iron OCRri biratu ez ezik, agian perspektiba duten dokumentuak irakurtzeko gaitasuna ere ematen dio Iron OCRri , testu dokumentuen argazkiak adibidez.

ReadBarcodes funtzio erabilgarria da eta IronOCR-k orrialdeetako barra-kodeak eta QR kodeak automatikoki irakurtzeko aukera ematen du testua ere irakurtzen baitu, denbora gehigarri handirik gehitu gabe.

KoloreSakonera. Ezarpen honek OCR liburutegiak kolore bakoitzeko sakonera zehazteko pixeleko zenbat bit erabiliko dituen zehazten du. Kolorearen sakonera altuagoak OCR kalitatea handitu dezake, baina OCR eragiketa burutzeko behar den denbora ere handituko da.

126 hizkuntza pakete

IronOCR-k nazioarteko 126 hizkuntza onartzen ditu DLL gisa banatzen diren hizkuntza paketeen bidez, webgune honetatik deskargatu daitezkeenak edo NuGet Package Manager- etik ere.

Hizkuntzen artean, alemana, frantsesa, ingelesa, txinera, japoniera eta beste asko daude. Hizkuntza pakete espezializatuak daude MRZ pasaportea, MICR egiaztapenak, datu ekonomikoak, matrikulak eta askoz gehiago. Tesseract ".traineddata" fitxategia ere erabil dezakezu - zuk zeuk sortutakoak barne.

Hizkuntza adibidea
