Protocols

The following protocols are available globally.

  • 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>

  • 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>

  • 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).
