    FaceLandmarkerOptions

      class 
 FaceLandmarkerOptions 
 : 
  TaskOptions 
 
 , 
 NSCopying

    Options for setting up a FaceLandmarker .

    • Running mode of the face landmark dection task. Defaults to .image . FaceLandmarker 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

      Swift

        var 
 runningMode 
 : 
  RunningMode 
 
 { 
 get 
 set 
 }

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

      Declaration

      Swift

        weak 
 var 
 faceLandmarkerLiveStreamDelegate 
 : 
  FaceLandmarkerLiveStreamDelegate 
 
 ? 
 { 
 get 
 set 
 }

    • The maximum number of faces can be detected by the FaceLandmarker. Defaults to 1.

      Declaration

      Swift

        var 
 numFaces 
 : 
 Int 
 { 
 get 
 set 
 }

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

      Declaration

      Swift

        var 
 minFaceDetectionConfidence 
 : 
 Float 
 { 
 get 
 set 
 }

    • The minimum confidence score of face presence score in the face landmark detection. Defaults to 0.5.

      Declaration

      Swift

        var 
 minFacePresenceConfidence 
 : 
 Float 
 { 
 get 
 set 
 }

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

      Declaration

      Swift

        var 
 minTrackingConfidence 
 : 
 Float 
 { 
 get 
 set 
 }

    • Whether FaceLandmarker outputs face blendshapes classification. Face blendshapes are used for rendering the 3D face model.

      Declaration

      Swift

        var 
 outputFaceBlendshapes 
 : 
 Bool 
 { 
 get 
 set 
 }

    • Whether FaceLandmarker outputs facial transformation_matrix. Facial transformation matrix is used to transform the face landmarks in canonical face to the detected face, so that users can apply face effects on the detected landmarks.

      Declaration

      Swift

        var 
 outputFacialTransformationMatrixes 
 : 
 Bool 
 { 
 get 
 set 
 }
