Protocols

The following protocols are available globally.

• MPPFaceDetectorLiveStreamDelegate

  This protocol defines an interface for the delegates of FaceDetector face to receive results of performing asynchronous face detection on images (i.e, when runningMode = .liveStream).

  The delegate of FaceDetector must adopt FaceDetectorLiveStreamDelegate protocol. The methods in this protocol are optional.

  Declaration

  Objective-C

  @protocol MPPFaceDetectorLiveStreamDelegate <NSObject>

• MPPFaceLandmarkerLiveStreamDelegate

  This protocol defines an interface for the delegates of FaceLandmarker face to receive results of performing asynchronous face detection on images (i.e, when runningMode = .liveStream).

  The delegate of FaceLandmarker must adopt FaceLandmarkerLiveStreamDelegate protocol. The methods in this protocol are optional.

  Declaration

  Objective-C

  @protocol MPPFaceLandmarkerLiveStreamDelegate <NSObject>

• MPPGestureRecognizerLiveStreamDelegate

  This protocol defines an interface for the delegates of GestureRecognizer object to receive results of performing asynchronous gesture recognition on images (i.e, when runningMode = .liveStream).

  The delegate of GestureRecognizer must adopt GestureRecognizerLiveStreamDelegate protocol. The methods in this protocol are optional.

  Declaration

  Objective-C

  @protocol MPPGestureRecognizerLiveStreamDelegate <NSObject>

• MPPHandLandmarkerLiveStreamDelegate

  This protocol defines an interface for the delegates of HandLandmarker object to receive results of performing asynchronous hand landmark detection on images (i.e, when runningMode = .liveStream).

  The delegate of HandLandmarker must adopt HandLandmarkerLiveStreamDelegate protocol. The methods in this protocol are optional.

  Declaration

  Objective-C

  @protocol MPPHandLandmarkerLiveStreamDelegate <NSObject>

• MPPImageClassifierLiveStreamDelegate

  This protocol defines an interface for the delegates of ImageClassifier object to receive results of asynchronous classification of images (i.e, when runningMode = .liveStream).

  The delegate of ImageClassifier must adopt ImageClassifierLiveStreamDelegate protocol. The methods in this protocol are optional.

  Declaration

  Objective-C

  @protocol MPPImageClassifierLiveStreamDelegate <NSObject>

• MPPObjectDetectorLiveStreamDelegate

  This protocol defines an interface for the delegates of ObjectDetector object to receive results of performing asynchronous object detection on images (i.e, when runningMode = .liveStream).

  The delegate of ObjectDetector must adopt ObjectDetectorLiveStreamDelegate protocol. The methods in this protocol are optional.

  Declaration

  Objective-C

  @protocol MPPObjectDetectorLiveStreamDelegate <NSObject>
