Car plate recognition settings

Aspose.OCR for Python via .NET allows for very flexible customization of vehicle license plate recognition accuracy, performance, and other settings by configuring the properties of the CarPlateRecognitionSettings object.

These settings are specifically tailored for processing scanned or photographed vehicle license plates (car plates).

Setting	Type	Default value	Description
allowed_symbols	string	All characters of the selected language	The whitelist of characters Aspose.OCR engine will look for.
ignored_symbols	string	none	A blacklist of characters that are ignored during recognition.
language	Language	Language.NONE	Specify a language for recognition.
automatic_color_inversion	boolean	true	Improve recognition accuracy of white text on a dark/black background. If you are not optimizing every aspect of recognition (for example, for online applications or entry-level devices), leave this setting set to true.

Applicable to

• Extracting text from a car plate

Example

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

# Instantiate Aspose.OCR API
api = AsposeOcr()
# Add images to the recognition batch
input = OcrInput(InputType.SINGLE_IMAGE)
input.add("car1.png")
input.add("car2.png")
# Customize recognition settings
recognitionSettings = CarPlateRecognitionSettings()
recognitionSettings.language = Language.LATIN
# Recognize license plates
result = api.recognize_car_plate(input, recognitionSettings)
# Print recognition result
print(result[0].recognition_text)
input("Press Enter to continue...")
