Options for setting up a FaceLandmarker
.
-
Running mode of the face landmark dection task. Defaults to
.image.FaceLandmarkercan be created with one of the following running modes:-
.image: The mode for performing face detection on single image inputs. -
.video: The mode for performing face detection on the decoded frames of a video. -
.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
FaceLandmarkerLiveStreamDelegateprotocol. This object must implementfaceLandmarker(_:didFinishDetectionWithResult:timestampInMilliseconds:error:)to receive the results of performing asynchronous face landmark detection on images (i.e, whenrunningMode=.liveStream).Declaration
Objective-C
@property ( nonatomic , weak , nullable ) id < MPPFaceLandmarkerLiveStreamDelegate > faceLandmarkerLiveStreamDelegate ; -
The maximum number of faces can be detected by the FaceLandmarker. Defaults to 1.
Declaration
Objective-C
@property ( nonatomic ) NSInteger numFaces ; -
The minimum confidence score for the face detection to be considered successful. Defaults to 0.5.
Declaration
Objective-C
@property ( nonatomic ) float minFaceDetectionConfidence ; -
The minimum confidence score of face presence score in the face landmark detection. Defaults to 0.5.
Declaration
Objective-C
@property ( nonatomic ) float minFacePresenceConfidence ; -
The minimum confidence score for the face tracking to be considered successful. Defaults to 0.5.
Declaration
Objective-C
@property ( nonatomic ) float minTrackingConfidence ; -
Whether FaceLandmarker outputs face blendshapes classification. Face blendshapes are used for rendering the 3D face model.
Declaration
Objective-C
@property ( nonatomic ) BOOL outputFaceBlendshapes ; -
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
Objective-C
@property ( nonatomic ) BOOL outputFacialTransformationMatrixes ;
