Public Methods

public final FaceLandmarker.FaceLandmarkerOptions build ()

Validates and builds the FaceLandmarker.FaceLandmarkerOptions instance.

Throws

IllegalArgumentException	if the result listener and the running mode are not properly configured. The result listener should only be set when the face landmarker is in the live stream mode.

public abstract FaceLandmarker.FaceLandmarkerOptions.Builder setBaseOptions (BaseOptions value)

Sets the base options for the face landmarker task.

Parameters

value

public abstract FaceLandmarker.FaceLandmarkerOptions.Builder setErrorListener (ErrorListener value)

Sets an optional error listener.

Parameters

value

public abstract FaceLandmarker.FaceLandmarkerOptions.Builder setMinFaceDetectionConfidence (Float value)

Sets minimum confidence score for the face detection to be considered successful

Parameters

value

public abstract FaceLandmarker.FaceLandmarkerOptions.Builder setMinFacePresenceConfidence (Float value)

Sets minimum confidence score of face presence score in the face landmark detection.

Parameters

value

public abstract FaceLandmarker.FaceLandmarkerOptions.Builder setMinTrackingConfidence (Float value)

Sets the minimum confidence score for the face tracking to be considered successful.

Parameters

value

public abstract FaceLandmarker.FaceLandmarkerOptions.Builder setNumFaces (Integer value)

Sets the maximum number of faces can be detected by the FaceLandmarker.

Parameters

value

public abstract FaceLandmarker.FaceLandmarkerOptions.Builder setOutputFaceBlendshapes (Boolean value)

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

Parameters

value

public abstract FaceLandmarker.FaceLandmarkerOptions.Builder setOutputFacialTransformationMatrixes (Boolean value)

Whether FaceLandmarker outptus 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.

Parameters

value

public abstract FaceLandmarker.FaceLandmarkerOptions.Builder setResultListener (ResultListener<FaceLandmarkerResult, MPImage> value)

Sets the result listener to receive the detection results asynchronously when the face landmarker is in the live stream mode.

Parameters

value

public abstract FaceLandmarker.FaceLandmarkerOptions.Builder setRunningMode (RunningMode value)

Sets the running mode for the face landmarker task. Default to the image mode. Hand landmarker has three modes:

• IMAGE: The mode for detecting face landmarks on single image inputs.
• VIDEO: The mode for detecting face landmarks on the decoded frames of a video.
• LIVE_STREAM: The mode for for detecting face landmarks on a live stream of input data, such as from camera. In this mode, setResultListener must be called to set up a listener to receive the detection results asynchronously.

Parameters

value
