Declaration
@interface VNDetectFaceCaptureQualityRequest : VNImageOverview
This request produces or updates a VNFace object's property face with a floating-point value. The float will be a value between 0 and 1. Faces with quality closer to 1 are better lit, sharper, and centrally positioned than faces with quality closer to 0. If the request fails, or the face observation has never been processed, the property face will be nil.
