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 takes OcrInput object and returns a RecognitionResult object containing the passport data.

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add images to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("passport1.png");
input.Add("passport2.png");
// Recognition settings
Aspose.OCR.PassportRecognitionSettings recognitionSettings = new Aspose.OCR.PassportRecognitionSettings();
recognitionSettings.Language = Aspose.OCR.Language.Latin;
// Recognize passports
List<Aspose.OCR.RecognitionResult> results = recognitionEngine.RecognizePassport(input, recognitionSettings);
foreach(Aspose.OCR.RecognitionResult result in results)
{
	Console.WriteLine(result.RecognitionText);
}
