Public Methods

public final FaceDetector.FaceDetectorOptions build ()

Validates and builds the FaceDetector.FaceDetectorOptions 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 detector is in the live stream mode.

public abstract FaceDetector.FaceDetectorOptions.Builder setBaseOptions (BaseOptions value)

Sets the BaseOptions for the face detector task.

Parameters

value

public abstract FaceDetector.FaceDetectorOptions.Builder setErrorListener (ErrorListener value)

Sets an optional ErrorListener}.

Parameters

value

public abstract FaceDetector.FaceDetectorOptions.Builder setMinDetectionConfidence (Float value)

Sets the minimum confidence score for the face detection to be considered successful. The default minDetectionConfidence is 0.5.

Parameters

value

public abstract FaceDetector.FaceDetectorOptions.Builder setMinSuppressionThreshold (Float value)

Sets the minimum non-maximum-suppression threshold for face detection to be considered overlapped. The default minSuppressionThreshold is 0.3.

Parameters

value

public abstract FaceDetector.FaceDetectorOptions.Builder setResultListener (ResultListener<FaceDetectorResult, MPImage> value)

Sets the OutputHandler.ResultListener to receive the detection results asynchronously when the face detector is in the live stream mode.

Parameters

value

public abstract FaceDetector.FaceDetectorOptions.Builder setRunningMode (RunningMode value)

Sets the RunningMode for the face detector task. Default to the image mode. face detector has three modes:

• IMAGE: The mode for detecting faces on single image inputs.
• VIDEO: The mode for detecting faces on the decoded frames of a video.
• LIVE_STREAM: The mode for for detecting faces 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
