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
