Public Methods

public final GestureRecognizer.GestureRecognizerOptions build ()

Validates and builds the GestureRecognizer.GestureRecognizerOptions instance.

Throws

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

public abstract GestureRecognizer.GestureRecognizerOptions.Builder setBaseOptions (BaseOptions value)

Sets the base options for the gesture recognizer task.

Parameters

value

public abstract GestureRecognizer.GestureRecognizerOptions.Builder setCannedGesturesClassifierOptions (ClassifierOptions classifierOptions)

Sets the optional ClassifierOptions controlling the canned gestures classifier, such as score threshold, allow list and deny list of gestures. The categories for canned gesture classifiers are: ["None", "Closed_Fist", "Open_Palm", "Pointing_Up", "Thumb_Down", "Thumb_Up", "Victory", "ILoveYou"]

TODO Note this option is subject to change, after scoring merging calculator is implemented.

Parameters

classifierOptions

public abstract GestureRecognizer.GestureRecognizerOptions.Builder setCustomGesturesClassifierOptions (ClassifierOptions classifierOptions)

Sets the optional ClassifierOptions controlling the custom gestures classifier, such as score threshold, allow list and deny list of gestures.

TODO Note this option is subject to change, after scoring merging calculator is implemented.

Parameters

classifierOptions

public abstract GestureRecognizer.GestureRecognizerOptions.Builder setErrorListener (ErrorListener value)

Sets an optional error listener.

Parameters

value

public abstract GestureRecognizer.GestureRecognizerOptions.Builder setMinHandDetectionConfidence (Float value)

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

Parameters

value

public abstract GestureRecognizer.GestureRecognizerOptions.Builder setMinHandPresenceConfidence (Float value)

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

Parameters

value

public abstract GestureRecognizer.GestureRecognizerOptions.Builder setMinTrackingConfidence (Float value)

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

Parameters

value

public abstract GestureRecognizer.GestureRecognizerOptions.Builder setNumHands (Integer value)

Sets the maximum number of hands can be detected by the GestureRecognizer.

Parameters

value

public abstract GestureRecognizer.GestureRecognizerOptions.Builder setResultListener (ResultListener<GestureRecognizerResult, MPImage> value)

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

Parameters

value

public abstract GestureRecognizer.GestureRecognizerOptions.Builder setRunningMode (RunningMode value)

Sets the running mode for the gesture recognizer task. Default to the image mode. Gesture recognizer has three modes:

• IMAGE: The mode for recognizing gestures on single image inputs.
• VIDEO: The mode for recognizing gestures on the decoded frames of a video.
• LIVE_STREAM: The mode for for recognizing gestures 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 recognition results asynchronously.

Parameters
