VNFaceObservationMBS.faceCaptureQuality as Variant

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Vision	MBS MacFrameworks Plugin	19.4	✅ Yes	❌ No	❌ No	✅ Yes	All

The capture quality of the face, normalized between 0.0 and 1.0.

The capture quality of the face allows you to compare the quality of the face in terms of its capture attributes: lighting, blur, and prime positioning. Use this metric to compare the capture quality of a face against other captures of the same face in a given set. Faces with quality closer to 1.0 are better lit, sharper, and centrally positioned than faces with quality closer to 0.0.
