כיצד לחלץ טקסט מתמונה באמצעות Java API?

AsposeOCR api = new AsposeOCR();
// Customize recognition
RecognitionSettings recognitionSettings = new RecognitionSettings();
recognitionSettings.setLanguage(Language.Ukr);
// Extract text from image
RecognitionResult result = api.RecognizePage("source.png", recognitionSettings);
// Show non-critical recognition problems
result.warnings.forEach((w) -> {
	System.out.println(w);
});
// Get recognition results as JSON
String resultJson = result.GetJson();

כיצד לחלץ טקסט בתוך מלבן באמצעות Java API?

AsposeOCR api = new AsposeOCR();
// Define image regions
ArrayList regions = new ArrayList();
regions.add(new Rectangle(231,101,430,42));
regions.add(new Rectangle(546,224,123,26));
// Specify recognition settings
RecognitionSettings recognitionSettings = new RecognitionSettings();
recognitionSettings.setAutoDenoising(true);	
recognitionSettings.setRecognitionAreas(regions);
// Extract text from selected regions
RecognitionResult result = api.RecognizePage("source.png", recognitionSettings);
System.out.println("Name: " + result.recognitionAreasText.get(0));
System.out.println("Expiry: " + result.recognitionAreasText.get(1));

זיהוי אזורי מסמכים אוטומטי באמצעות Java API

 // Create instance of OCR API
AsposeOCR api = new AsposeOCR();
// Enable automatic document areas detection
RecognitionSettings recognitionSettings = new RecognitionSettings();
recognitionSettings.setAllowedCharacters(CharactersAllowedType.LATIN_ALPHABET);
recognitionSettings.setDetectAreas(true);
// Extract text from image
RecognitionResult result = api.RecognizePage("source.png", recognitionSettings);
System.out.println("Recognition result:\n" + result.recognitionText + "\n\n");
