OCR ପରତଛବ ଫଲଟରଗଡକର ତାଲକା |

OCR କାରଯୟଦକଷତା ବଦଧ କରବାକ ଇନପଟ ଫଲଟର ଯାହା IronOCR ରେ ନରମତ:

  • OcrInput.Rotate(double degrees) - Rotates the image a number of degrees clockwise. For counterclockwise, use a negative number.
  • OcrInput.Binarize() - This image filter turns each pixel black or white. Useful where there is low-contrast text on a background and OCR performance improves.
  • OcrInput.ToGrayScale() - Converts each pixel to grayscale. Might not increase OCR accuracy but can improve speed.
  • OcrInput.Contrast() - Automatically increases contrast. Improves OCR speed and accuracy especially on low contrast scans.
  • OcrInput.DeNoise() - Removes digital noise. Should be used wherever noise is expected.
  • OcrInput.Invert(/csharp/ocr/languages/strong> - Inverts each color (e.g., white becomes black; black becomes white/).
  • OcrInput.Dilate() - Enhanced morphology, adds pixels around the boundary of objects in the image. Opposite of Erode.
  • OcrInput.Erode() - Enhanced morphology, removes pixels on object boundaries. Opposite of Dilate.
  • OcrInput.Deskew() - Rotates image so that it is upright and orthogonally aligned. Essential for accuracy, the 5-degree tolerance of Tesseract is improved.
  • OcrInput.DeepCleanBackgroundNoise() - Removes heavy background noise. Use only where known, as it can lower OCR accuracy on clean documents and is CPU intensive.
  • OcrInput.EnhanceResolution - Increases resolution of low-quality images. Automatically handles low res inputs using MinimumDPI and TargetDPI properties.

Clean Background Noise is a setting that is time-sensitive but allows the library to automatically clean digital noise, paper shreds, and other artifacts, which other libraries cannot.

Enhance Contrast automatically increases image text contrast and improves OCR accuracy, thereby generally increasing performance and speed.

Enhance Resolution detects low-resolution images (<275 dpi) and auto-upscales them for sharp text. This operation is timely but often faster overall for OCR ops.

Language settings support multiple languages, useful for translating foreign documents.

126 ଭାଷା ପୟାକ |

IronOCR supports 126 ଆନତରଜାତୀୟ ମାଗଣା languages distributed as DLLs; downloadable from this website or NuGet.

Included languages span German, French, English, Chinese, Japanese, and many more. Specialist packages exist for MRZ, MICR, license plates, and others. Any Tesseract ".traineddata" files you have can be used, including your custom-made ones.

Language Example |

Using another OCR language: 

using IronOcr;
// PM> Install IronOcr.Languages.Arabic

var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.Arabic;

using (var input = new OcrInput())
{
    input.AddImage("img/arabic.gif");
    // Add image noise filters if needed
    // In this case, the input might be of very poor quality
    // IronTesseract can read what conventional ones cannot

    var Result = Ocr.Read(input);

    // Saving Arabic text - cannot print Arabic easily in console on Windows
    Result.SaveAsTextFile("arabic.txt");
}
using IronOcr;
// PM> Install IronOcr.Languages.Arabic

var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.Arabic;

using (var input = new OcrInput())
{
    input.AddImage("img/arabic.gif");
    // Add image noise filters if needed
    // In this case, the input might be of very poor quality
    // IronTesseract can read what conventional ones cannot

    var Result = Ocr.Read(input);

    // Saving Arabic text - cannot print Arabic easily in console on Windows
    Result.SaveAsTextFile("arabic.txt");
}
Imports IronOcr
' PM> Install IronOcr.Languages.Arabic

Private Ocr = New IronTesseract()
Ocr.Language = OcrLanguage.Arabic

Using input = New OcrInput()
	input.AddImage("img/arabic.gif")
	' Add image noise filters if needed
	' In this case, the input might be of very poor quality
	' IronTesseract can read what conventional ones cannot

	Dim Result = Ocr.Read(input)

	' Saving Arabic text - cannot print Arabic easily in console on Windows
	Result.SaveAsTextFile("arabic.txt")
End Using

Multiple Language Example |

Using multiple languages in one go is possible, aiding in receiving metadata in multiple languages from runtime OCR: 

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

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

// Any number of additional languages can be added

using (var input = new OcrInput())
{
    input.Add("multi-language.pdf");
    var Result = Ocr.Read(input);
    Result.SaveAsTextFile("results.txt");
}
using IronOcr;
// PM> Install IronOcr.Languages.ChineseSimplified

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

// Any number of additional languages can be added

using (var input = new OcrInput())
{
    input.Add("multi-language.pdf");
    var Result = Ocr.Read(input);
    Result.SaveAsTextFile("results.txt");
}
Imports IronOcr
' PM> Install IronOcr.Languages.ChineseSimplified

Private Ocr = New IronTesseract()
Ocr.Language = OcrLanguage.ChineseSimplified
Ocr.AddSecondaryLanguage(OcrLanguage.Oriya)

' Any number of additional languages can be added

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