FaceLandmarkerLiveStreamDelegate
protocol FaceLandmarkerLiveStreamDelegate : NSObjectProtocol
This protocol defines an interface for the delegates of FaceLandmarker
face to receive
results of performing asynchronous face detection on images (i.e, when runningMode
=
.liveStream
).
The delegate of FaceLandmarker
must adopt FaceLandmarkerLiveStreamDelegate
protocol.
The methods in this protocol are optional.
This method notifies a delegate that the results of asynchronous face detection of
an image submitted to the FaceLandmarker
is available.
This method is called on a private serial dispatch queue created by the FaceLandmarker
for performing the asynchronous delegates calls.
Declaration
Swift
func faceLandmarker ( _ faceLandmarker : MPPFaceLandmarker , didFinishDetection result : FaceLandmarkerResult ?, timestampInMilliseconds : Int , error : Error ?)
Parameters
faceLandmarker
The face landmarker which performed the face landmark detctions.
This is useful to test equality when there are multiple instances of FaceLandmarker
.
result
timestampInMilliseconds
The timestamp (in milliseconds) which indicates when the input
image was sent to the face detector.
error
An optional error parameter populated when there is an error in performing face
detection on the input live stream image data.
