Lis OCR Filtè Imaj

Filtè Antre amelyore pèfòmans OCR ki fè yo bati nan IronOCR gen ladan yo:

  • OcrInput.Rotate(double degrees) - Thorne imaj pa yon kantite degre goch. Pou anti-goch, itilize nimewo negatif.
  • OcrInput.Binarize() - Sa a filtre imaj vire chak pixel nwa oswa blan ki pa gen okenn tè presegondè. Ka amelyore ka pèfòmans OCR nan kontras ki ba anpil nan tèks background.
  • OcrInput.ToGrayScale() - Sa a filtre imaj vire chak pixel nan yon lonbraj nan gri. Fasil amelyore presizyon OCR men li ka amelyore vitès.
  • OcrInput.Contrast() - Ogmante kontras otomatikman. Sa a filtre souvan amelyore OCR vitès ak presizyon nan analiz kontras ki ba.
  • OcrInput.DeNoise() - Retire bri dijital. Filtè sa a ta dwe itilize sèlman kote bri espere.
  • OcrInput.Invert() - Envèse chak koulè. Eg. Blan vin nwa: nwa vin blan.
  • OcrInput.Dilate() - Mòfoloji avanse. Dilatasyon ajoute piksèl nan limit objè nan yon imaj. Opoze a Erode.
  • OcrInput.Erode() - Mòfoloji avanse. Ewozyon retire piksèl sou limit objè. Opoze nan dilate.
  • OcrInput.Deskew() - Thorne yon imaj kidonk li se yon fason a dwat leve, li orthogonal. Sa a trè itil pou OCR paske tolerans Tesseract pou analiz fose ka osi ba ke 5 degre.
  • OcrInput.DeepCleanBackgroundNoise() - Gwo retire bri background. Sèvi sèlman ak filtè sa a nan ka ekstrèm bri background dokiman li te ye, paske sa a filtre ap riske tou diminye OCR presizyon nan dokiman pwòp, e li trè CPU chè.
  • OcrInput.EnhanceResolution - Amelyore rezolisyon an nan imaj bon jan kalite ki ba. Filtre sa a pa souvan nesesè paske OcrInput.MinimumDPI ak OcrInput.TargetDPI pral otomatikman trape ak rezoud opinyon rezolisyon ki ba.

CleanBackgroundNoise. Sa a se yon anviwònman ki se yon ti jan tan konsome; sepandan, li pèmèt bibliyotèk la otomatikman netwaye bri dijital, papye chifonnen, ak lòt defo nan yon imaj dijital ki ta otreman rann li anmezi pou yo te li pa lòt bibliyotèk OCR.

EnhanceContrast se yon anviwònman ki lakòz IronOCR otomatikman ogmante kontras nan tèks kont background nan nan yon imaj, ogmante presizyon nan OCR epi jeneralman ogmante pèfòmans ak vitès la nan OCR.

EnhanceResolution se yon anviwònman ki pral otomatikman detekte imaj ki ba-rezolisyon (ki se anba 275 DPI) ak otomatikman pwolongasyon imaj la ak Lè sa a egwize tout tèks la pou li ka li parfe pa yon bibliyotèk OCR. Malgre ke operasyon sa a se nan tèt li tan konsome, li jeneralman diminye tan an jeneral pou yon operasyon OCR sou yon imaj.

Lang IronOCR sipòte 22 pake lang entènasyonal, epi yo ka anviwònman an lang dwe itilize yo chwazi youn oswa plis plizyè lang yo dwe aplike pou yon operasyon OCR.

Estrateji IronOCR sipòte de estrateji. Nou ka chwazi swa ale pou yon eskanè vit ak mwens egzat nan yon dokiman, oswa itilize yon estrateji avanse ki itilize kèk modèl entèlijans atifisyèl otomatikman amelyore presizyon nan tèks OCR pa gade nan relasyon estatistik mo youn ak lòt nan yon fraz.

ColorSpace se yon anviwònman kote nou ka chwazi OCR nan gri oswa koulè. Anjeneral, gri se opsyon ki pi bon. Sepandan, pafwa lè gen tèks oswa orijin nan Hue ki sanble, men trè diferan koulè, yon espas koulè plen-koulè ap bay pi bon rezilta.

DetectWhiteTextOnDarkBackgrounds. Anjeneral, tout bibliyotèk OCR espere wè tèks nwa sou orijin blan. Anviwònman sa a pèmèt IronOCR otomatikman detekte negatif, oswa paj nwa ak tèks blan, epi li yo.

InputImageType. Anviwònman sa a pèmèt pwomotè a gide bibliyotèk la OCR kòm si li se kap nan yon dokiman konplè oswa yon brib, tankou yon D.

RotateAndStraighten se yon anviwònman avanse ki pèmèt IronOCR kapasite inik nan li dokiman ki pa sèlman Thorne, men petèt ki gen pèspektiv, tankou foto nan dokiman tèks.

ReadBarcodes se yon karakteristik itil ki pèmèt IronOCR otomatikman li kòd bar ak kòd QR nan paj jan li li tèks tou, san yo pa ajoute yon gwo chay tan anplis.

KoulèDepth. Anviwònman sa a detèmine konbyen Bits pou chak pixel bibliyotèk la OCR pral itilize detèmine pwofondè nan yon koulè. Yon pwofondè koulè ki pi wo ka ogmante bon jan kalite OCR, men ap ogmante tou tan ki nesesè pou operasyon OCR la fini.

126 pake lang

IronOCR sipòte 126 lang entènasyonal atravè pake lang ki distribiye kòm DLL, ki ka telechaje sou sit entènèt sa a, oswa tou nan Manadjè Pakè NuGet la.

Lang yo enkli Alman, franse, angle, Chinwa, Japonè ak anpil plis. Pake lang espesyalis egziste pou paspò MRZ, chèk MICR, done finansye, plak machin ak anpil plis. Ou kapab tou itilize nenpòt dosye tesseract ".traineddata" ki gen ladan yo ou kreye tèt ou.

Egzanp plizyè lang

Li posib tou pou OCR lè l sèvi avèk plizyè lang an menm tan. Sa ka vrèman ede jwenn metadata ak URL urls nan dokiman Unicode yo.

// using IronOcr;
// PM> Install-Package IronOcr.Languages.ChineseSimplified

var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.ChineseSimplified;
Ocr.AddSecondaryLanguage(OcrLanguage.Haitian);

// Nou ka ajoute nenpòt ki kantite lang

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

    Result.SaveAsTextFile("results.txt");
}
// using IronOcr;
// PM> Install-Package IronOcr.Languages.ChineseSimplified

var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.ChineseSimplified;
Ocr.AddSecondaryLanguage(OcrLanguage.Haitian);

// Nou ka ajoute nenpòt ki kantite lang

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

    Result.SaveAsTextFile("results.txt");
}
' using IronOcr;

Dim Ocr = New IronTesseract()
Ocr.Language = OcrLanguage.ChineseSimplified
Ocr.AddSecondaryLanguage(OcrLanguage.Haitian)

' Nou ka ajoute nenpòt ki kantite lang

Using input = New OcrInput()
	input.Add("multi-language.pdf")
	Dim Result = Ocr.Read(input)

Rezilta OCR Detaye objè yo

IronOCR retounen yon objè rezilta OCR pou chak operasyon OCR. Anjeneral, devlopè sèlman itilize pwopriyete tèks objè sa a pou yo ka tcheke tèks la nan imaj la. Sepandan, rezilta OCR DOM yo pi avanse pase sa.

using IronOcr;
using System.Drawing; // Ajoute Referans Asanble

var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.Haitian;
Ocr.Configuration.EngineMode = TesseractEngineMode.TesseractAndLstm;
Ocr.Configuration.ReadBarCodes = true; // Enpòtan

using (var Input = new OcrInput(@"images\sample.tiff"))
{
    OcrResult Result = Ocr.Read(Input);
    var Pages = Result.Pages;
    var Words = Pages[0].Words;
    var Barcodes = Result.Barcodes;
    // Eksplore isit la pou jwenn yon masiv, API detaye:
    // - Paj, blòk, paraphaf, Liy, Mo, Chars
    // - Imaj Export, Polis kowòdone, Done estatistik

Pèfòmans

IronOCR travay soti nan bwat la ki pa gen okenn bezwen melodi pèfòmans oswa lou modifye imaj opinyon.

Vitès se tou limen an: IronOcr.2020 + se jiska 10 fwa pi vit epi fè plis pase 250% mwens erè pase bati anvan yo.
