Extracting text from passport images

Automatic passport recognition and verification is a very common task in many areas: border control, banking, security, and so on. However, manually re-typing text is an error-prone and time-consuming process, and mistakes can lead to security breaches and other undesirable consequences.

Aspose.OCR offers a special recognition algorithm that extracts text from scanned or photographed passports, which can then be automatically saved to the database or automatically verified.

To extract text from a passport image, use RecognizePassport method of Aspose.OCR.AsposeOcr class.

This method allows you to customize recognition accuracy, performance, and other settings.

The method returns a RecognitionResult object containing the passport data.

Read passport from path

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
Aspose.OCR.PassportRecognitionSettings recognitionSettings = new Aspose.OCR.PassportRecognitionSettings();
recognitionSettings.Language = Aspose.OCR.Language.Latin;
Aspose.OCR.RecognitionResult result = recognitionEngine.RecognizePassport("passport.png", recognitionSettings);
Console.WriteLine(result.RecognitionText);

Read passport from memory

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
Aspose.OCR.PassportRecognitionSettings recognitionSettings = new Aspose.OCR.PassportRecognitionSettings();
recognitionSettings.Language = Aspose.OCR.Language.Latin;
using(MemoryStream ms = new MemoryStream())
{
	using(FileStream fs = new FileStream("passport.png", FileMode.Open, FileAccess.Read))
	{
		fs.CopyTo(ms);
		Aspose.OCR.RecognitionResult result = recognitionEngine.RecognizePassport(ms, recognitionSettings);
		Console.WriteLine(result.RecognitionText);
	}
}
