    HandLandmarkerOptions

      class 
 HandLandmarkerOptions 
 : 
  TaskOptions 
 
 , 
 NSCopying

    Options for setting up a HandLandmarker .

    • Running mode of the hand landmarker task. Defaults to .image . HandLandmarker can be created with one of the following running modes:

      1. image : The mode for performing hand landmark detection on single image inputs.
      2. video : The mode for performing hand landmark detection on the decoded frames of a video.
      3. liveStream : The mode for performing hand landmark detection on a live stream of input data, such as from the camera.

      Declaration

      Swift

        var 
 runningMode 
 : 
  RunningMode 
 
 { 
 get 
 set 
 }

    • An object that confirms to HandLandmarkerLiveStreamDelegate protocol. This object must implement handLandmarker:didFinishDetectionWithResult:timestampInMilliseconds:error: to receive the results of performing asynchronous hand landmark detection on images (i.e, when runningMode = .liveStream ).

      Declaration

      Swift

        weak 
 var 
 handLandmarkerLiveStreamDelegate 
 : 
  HandLandmarkerLiveStreamDelegate 
 
 ? 
 { 
 get 
 set 
 }

    • The maximum number of hands that can be detected by the HandLandmarker .

      Declaration

      Swift

        var 
 numHands 
 : 
 Int 
 { 
 get 
 set 
 }

    • The minimum confidence score for the hand detection to be considered successful.

      Declaration

      Swift

        var 
 minHandDetectionConfidence 
 : 
 Float 
 { 
 get 
 set 
 }

    • The minimum confidence score of hand presence score in the hand landmark detection.

      Declaration

      Swift

        var 
 minHandPresenceConfidence 
 : 
 Float 
 { 
 get 
 set 
 }

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

      Declaration

      Swift

        var 
 minTrackingConfidence 
 : 
 Float 
 { 
 get 
 set 
 }
