The following code example shows how to fine-tune car plate recognition:

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);
// Recognition settings
Aspose.OCR.CarPlateRecognitionSettings recognitionSettings = new Aspose.OCR.CarPlateRecognitionSettings();
recognitionSettings.Language = Aspose.OCR.Language.Latin;
// Recognize license plates
List<Aspose.OCR.RecognitionResult> results = recognitionEngine.RecognizeCarPlate(input, recognitionSettings);
foreach(Aspose.OCR.RecognitionResult result in results)
