public LicensePlateDetectionRecognitionOptionBuilder DeliverPlatePictureInResult(bool value = true)Parameters
valuebool
Returns
DoAutomaticDetectionOptimization(bool)
Set the true to do optimization of the processing methods when the models are loaded the first time. Only enable when using the models for multiple detections.

Returns
Done()
Call this when done configuring this option Note: This method has to be the last method called in the builder chain.
public RecognitionOptionBuilder Done()Returns
SetPlateModelQuality(QualityPlateModel)
Set the quality of the license plate model. Only use this when you want to override the default quality. Note: When passing a model by stream, the quality is ignored.

Returns
SetRecognitionQuality(RecognitionQuality)
Sets the recognition quality for license plate detection. Note: When passing a model by stream, the quality is ignored.

qualityLicensePlateDetectionRecognitionOptionBuilder.RecognitionQualityThe desired recognition quality level to be set. This parameter determines the accuracy and speed of the recognition process.
Returns
- LicensePlateDetectionRecognitionOptionBuilder
The current instance of LicensePlateDetectionRecognitionOptionBuilder to allow for method chaining.

Returns
UseCroppedImageForRecognition()
Use cropped image for recognition. The image will be cropped (stretched) to fill the recognition area. Depending on the image aspect ratio, the image might be stretched horizontally or vertically so only the center part is taken for the recognition.

UseLocalModelsForRecognitionMode(RecognitionModeType)
Automated mode for loading the models from the local file system by specifying the recognition mode. The models have to be stored in the local file system with the correct naming convention for this to work. Sets the recognition mode for license plate detection by specifying the local model streams to use.

Returns
UseRecognitionModeCountryLicencePlateOnly(ModelStreamInfo?, ModelStreamInfo?, ModelStreamInfo?)
Manual mode for loading the models from the local file system by specifying the local model streams to use. This method is used when the models are loaded from the local file system but not with the correct naming convention or when the models are stored in different folders. Sets the recognition mode for license plate detection. First, it will try to detect the country license plate, then the license plate text.

UseRecognitionModeCountryLicencePlateThenVehicle(ModelStreamInfo?, ModelStreamInfo?, ModelStreamInfo?, ModelStreamInfo?)
Manual mode for loading the models from the local file system by specifying the local model streams to use. This method is used when the models are loaded from the local file system but not with the correct naming convention or when the models are stored in different folders. Sets the recognition mode for license plate detection. First, it will try to detect the country license plate, then the license plate text, and if possible the vehicle type surrounding the license plate. If no plate is detected, no result is returned.
