    Options for setting up a FaceDetector .

    • Running mode of the face detector task. Defaults to .image . FaceDetector can be created with one of the following running modes:

      1. .image : The mode for performing face detection on single image inputs.
      2. .video : The mode for performing face detection on the decoded frames of a video.
      3. .liveStream : The mode for performing face detection on a live stream of input data, such as from the camera.

      Declaration

      Objective-C

        @property 
 ( 
 nonatomic 
 ) 
  MPPRunningMode 
 
 runningMode 
 ;

    • An object that confirms to FaceDetectorLiveStreamDelegate protocol. This object must implement faceDetector(_:didFinishDetectionWithResult:timestampInMilliseconds:error:) to receive the results of performing asynchronous face detection on images (i.e, when runningMode = .liveStream ).

      Declaration

      Objective-C

        @property 
 ( 
 nonatomic 
 , 
 weak 
 , 
 nullable 
 ) 
 id 
 < 
  MPPFaceDetectorLiveStreamDelegate 
 
 > 
 faceDetectorLiveStreamDelegate 
 ;

    • The minimum confidence score for the face detection to be considered successful. Defaults to 0.5.

      Declaration

      Objective-C

        @property 
 ( 
 nonatomic 
 ) 
 float 
 minDetectionConfidence 
 ;

    • The minimum non-maximum-suppression threshold for face detection to be considered overlapped. Defaults to 0.3.

      Declaration

      Objective-C

        @property 
 ( 
 nonatomic 
 ) 
 float 
 minSuppressionThreshold 
 ;
