Għaliex Agħżel IronOCR?

IronOCR huwa librerija tas-softwer .NET faċli biex tinstalla, kompluta u dokumentata sew.

Agħżel IronOCR biex tikseb 99.8%+ preċiżjoni OCR mingħajr ma tuża xi servizzi tal-web esterni, miżati kontinwi jew tibgħat dokumenti kunfidenzjali fuq l-internet.

Għaliex l-iżviluppaturi ta' C# jagħżlu IronOCR fuq Vanilla Tesseract:

Installa bħala DLL wieħed jew NuGet
Jinkludi għal Magni Tesseract 5, 4 u 3 barra mill-kaxxa.
L-eżattezza 99.8% tissupera b'mod sinifikanti lil Tesseract regolari.
Veloċità tisreġ u MultiThreading
MVC, WebApp, Desktop, Console & Server Applikazzjoni kompatibbli
Ebda kodiċi Exes jew C++ biex taħdem magħhom
Appoġġ PDF OCR sħiħ
Biex twettaq OCR kważi kull fajl Image jew PDF
Appoġġ sħiħ .NET Core, Standard u FrameWork
Skjerja fuq Windows, Mac, Linux, Azure, Docker, Lambda, AWS
Aqra barcodes u kodiċijiet QR
Esporta OCR dwar XHTML
Esporta OCR għal dokumenti PDF li jistgħu jitfittxu
Appoġġ multithreading
126 lingwa internazzjonali kollha ġestiti permezz ta' fajls NuGet jew OcrData
Estratt Stampi, Koordinati, Statistiċi u Fonts. Mhux biss test.
Tista' tintuża biex tqassam mill-ġdid Tesseract OCR ġewwa applikazzjonijiet kummerċjali u proprjetarji.

IronOCR jiddi meta jaħdem bi stampi tad-dinja reali u dokumenti imperfetti bħal ritratti, jew skans ta' riżoluzzjoni baxxa li jista' jkollhom storbju jew imperfezzjonijiet diġitali.

Libreriji OCR oħra b'xejn għall-pjattaforma .NET. APIs oħra bħal dawn .net u servizzi tal-web ma jaħdmux daqshekk tajjeb f'dawn il-każijiet ta' użu fid-dinja reali.

OCR b'Tesseract 5 - Ibda Kodifika f'C#

Il-kampjun tal-kodiċi hawn taħt juri kemm hu faċli li taqra test minn stampa billi tuża C# jew VB .NET.

Lista ta' Filtri tal-Immaġni OCR

Filtri tal-input biex itejbu l-prestazzjoni tal-OCR li huma integrati f'IronOCR jinkludu:

OcrInput.Rotate (gradi doppji) - Dawwar l-immaġini b'numru ta' gradi lejn l-arloġġ. Għal kontra l-arloġġ, uża numri negattivi.
OcrInput.Binarize () - Dan il-filtru tal-immaġni jdawwar kull pixel iswed jew abjad mingħajr ebda triq tan-nofs. Jista' Jtejjeb il-każijiet ta' prestazzjoni OCR ta' kuntrast baxx ħafna ta' test ma' sfond.
OcrInput.ToGrayScale () - Dan il-filtru tal-immaġni jdawwar kull pixel fi dell ta' skala ta' griż. Mhux probabbli li ttejjeb il-preċiżjoni tal-OCR iżda tista' ttejjeb il-veloċità
OcrInput.Contrast () - Iżżid il-kuntrast awtomatikament. Dan il-filtru ħafna drabi jtejjeb il-veloċità u l-preċiżjoni tal-OCR fi skans ta' kuntrast baxx.
OcrInput.DeNoise () - Tneħħi l-istorbju diġitali. Dan il-filtru għandu jintuża biss fejn huwa mistenni l-istorbju.
OcrInput.Invert () - Jaqleb kull kulur. Eż. L-abjad isir iswed: l-iswed isir abjad.
OcrInput.Dilate () - Morfoloġija Avvanzata. Id-dilatazzjoni żżid il-pixels mal-konfini ta' oġġetti f'immaġni. Biswit l-Erode
OcrInput.Erode () - Morfoloġija Avvanzata. L-erożjoni tneħħi l-pixels fuq il-konfini tal-oġġett Opposite of Dilate
OcrInput.Deskew () - Dawwar immaġni u għalhekk hija t-triq it-tajba 'l fuq u ortogonali. Dan huwa utli ħafna għall-OCR minħabba li t-tolleranza tat-Tesseract għal skans distorti tista' tkun baxxa sa 5 gradi.
OcrInput.DeepCleanBackgroundNoise () - Tneħħija qawwija ta' storbju fl-isfond. Uża dan il-filtru biss f'każ li jkun magħruf storbju estrem fl-isfond tad-dokument, għax dan il-filtru jirriskja wkoll li jnaqqas il-preċiżjoni tal-OCR ta' dokumenti nodfa, u jiswa ħafna s-CPU.
OcrInput.EnhanceResolution - Ittejjeb ir-riżoluzzjoni ta' immaġini ta' kwalità baxxa. Dan il-filtru mhuwiex ta' spiss meħtieġ minħabba li OcrInput.MinimumDPI u OcrInput.TargetDPI awtomatikament jaqbdu u jsolvu inputs b'riżoluzzjoni baxxa.

CleanBackgroundNoise. Dan huwa ambjent li jieħu ftit ħin; madankollu, tippermetti li l-librerija tnaddaf awtomatikament ħsejjes diġitali, crumples tal-karta, u imperfezzjonijiet oħra fi ħdan immaġni diġitali li altrimenti jagħmluha inkapaċi li tinqara minn libreriji OCR oħra.

EnhanceContrast huwa issettjar li jikkawża li l-IronOCR iżid awtomatikament il-kuntrast tat-test fl-isfond ta' immaġni, iżid il-preċiżjoni tal-OCR u ġeneralment iżid il-prestazzjoni u l-veloċità tal-OCR.

EnhanceResolution huwa issettjar li awtomatikament jiskopri immaġini b'riżoluzzjoni baxxa (li huma taħt 275 dpi) u awtomatikament itejjeb l-immaġni u mbagħad ittejjeb it-test kollu sabiex ikun jista' jinqara perfettament minn librerija OCR. Għalkemm din l-operazzjoni fiha nnifisha tieħu ħafna ħin, ġeneralment tnaqqas il-ħin ġenerali għal operazzjoni OCR fuq stampa.

Language IronOCR jappoġġja 22 pakkett ta' lingwa internazzjonali, u l-issettjar tal-lingwa jista' jintuża biex tagħżel lingwa waħda jew aktar li għandhom jiġu applikati għal operazzjoni OCR.

Strateġija Ħadid OCR tappoġġja żewġ strateġiji. Aħna nistgħu nagħżlu li jew immorru għal skan mgħaġġel u inqas preċiż ta' dokument, jew nużaw strateġija avvanzata li tuża xi mudelli ta' intelliġenza artifiċjali biex awtomatikament ittejjeb l-eżattezza tat-test OCR billi tħares lejn ir-relazzjoni statistika tal-kliem lil xulxin f'sentenza.

ColorSpace huwa ambjent li bih nistgħu nagħżlu li OCR fi skala griża jew kulur. Ġeneralment, l-iskala tal-griż hija l-aħjar għażla. Madankollu, xi kultant meta jkun hemm testi jew sfondi ta' lewn simili iżda kulur differenti ħafna, spazju tal-kulur b'kulur sħiħ jipprovdi riżultati aħjar.

DetectWhiteTextOnDarkBackgrounds. Ġeneralment, il-libreriji OCR kollha jistennew li jaraw test iswed fuq sfondi bojod. Dan l-issettjar jippermetti lil IronOCR li awtomatikament jiskopri negattivi, jew paġni skuri b'test abjad, u jaqrahom.

InputImageType. Dan l-issettjar jippermetti lill-iżviluppatur jiggwida l-librerija OCR dwar jekk hux qed iħares lejn dokument sħiħ jew xi siltiet, bħal screenshot.

RotateAndStraighten huwa ambjent avvanzat li jippermetti lil IronOCR l-abbiltà unika li taqra dokumenti li mhux biss iduru, imma forsi fihom perspettiva, bħal ritratti ta' dokumenti ta' test.

ReadBarcodes hija karatteristika utli li tippermetti lill-IronOCR jaqra awtomatikament barcodes u kodiċijiet QR fuq il-paġni billi jaqra wkoll it-test, mingħajr ma jżid piż ta' ħin addizzjonali kbir.

Kulur Profond. Dan l-issettjar jiddetermina kemm bits kull pixel il-librerija OCR se tuża biex tiddetermina l-fond ta' kulur. Fond ta' kulur ogħla jista' jżid il-kwalità ta' l-OCR, iżda jżid ukoll il-ħin meħtieġ biex titlesta l-operazzjoni ta' l-OCR.

126 Pakketti Lingwistiċi

IronOCR jappoġġja 126 lingwa internazzjonali permezz ta’ pakketti lingwistiċi li huma mqassma bħala DLLs, li jistgħu jitniżżlu minn din il-websajt, jew ukoll mill- Maniġer tal-Pakketti NuGet.

Il-lingwi jinkludu Ġermaniż, Franċiż, Ingliż, Ċiniż, Ġappuniż u ħafna aktar. Pakketti lingwistiċi speċjalizzati jeżistu għal passaport MRZ, kontrolli MICR, Dejta Finanzjarja, Pjanċi tal-liċenzja u ħafna aktar. Tista' wkoll tuża kwalunkwe fajl ".traineddata" tesseract - inklużi dawk li toħloq int stess.

Eżempju ta' Lingwa Multipla

Huwa wkoll possibbli li OCR tuża lingwi multipli fl-istess ħin. Dan jista' verament jgħin biex tikseb metadata u urls tal-lingwa Ingliża f'dokumenti Unicode.

using IronOcr;

// PM> Install IronOcr.Languages.ChineseSimplified

// Initialize the OCR engine
var Ocr = new IronTesseract();

// Set primary language to Chinese Simplified
Ocr.Language = OcrLanguage.ChineseSimplified;

// Add Maltese as secondary language
Ocr.AddSecondaryLanguage(OcrLanguage.Maltese);

// Nistgħu nżidu kwalunkwe numru ta 'lingwi

using (var input = new OcrInput())
{
    input.Add("multi-language.pdf");

    // Perform OCR and save the result to a text file
    var Result = Ocr.Read(input);
    Result.SaveAsTextFile("results.txt");
}

Oġġetti Riżultati OCR Dettaljati

IronOCR jirritorna oġġett ta' riżultat OCR għal kull operazzjoni OCR. Ġeneralment, l-iżviluppaturi jużaw biss il-proprjetà tat-test ta' dan l-oġġett biex it-test jiġi skannjat mill-immaġni. Madankollu, ir-riżultati tal-OCR DOM huma ħafna aktar avvanzati minn dan.

Prestazzjoni

IronOCR jaħdem barra mill-kaxxa mingħajr l-ebda ħtieġa li jtejjeb il-prestazzjoni jew jimmodifika ħafna l-immaġini tad-dħul.

Speed is Blazing: IronOcr.2020+ huwa sa 10 darbiet aktar mgħaġġel u jagħmel aktar minn 250% inqas żbalji minn builds preċedenti.
