Instance Property

recognitionLevel

A value that determines whether the request prioritizes accuracy or speed in text recognition.

Declaration

var recognitionLevel: VNRequestTextRecognitionLevel { get set }

Discussion

The recognition level determines which techniques are used during the text recognition. Set this value to VNRequestTextRecognitionLevel.fast to prioritize speed over accuracy, and to VNRequestTextRecognitionLevel.accurate for longer, more computationally intensive recognition.
