MPPFaceLandmarkerResult

@interface MPPFaceLandmarkerResult : MPPTaskResult

Represents the detection results generated by FaceLandmarker.

• faceLandmarks

  Detected face landmarks in normalized image coordinates.

  Declaration

  Objective-C

  @property (nonatomic, readonly) NSArray<NSArray<MPPNormalizedLandmark *> *> *_Nonnull faceLandmarks;

• faceBlendshapes

  Face blendshapes results. Defaults to an empty array if not enabled.

  Declaration

  Objective-C

  @property (nonatomic, readonly) NSArray<MPPClassifications *> *_Nonnull faceBlendshapes;

• facialTransformationMatrixes

  Facial transformation 4x4 matrices. Defaults to an empty array if not enabled.

  Declaration

  Objective-C

  @property (nonatomic, readonly) NSArray<MPPTransformMatrix *> *_Nonnull facialTransformationMatrixes;

• -initWithFaceLandmarks:faceBlendshapes:facialTransformationMatrixes:timestampInMilliseconds:

  Initializes a new FaceLandmarkerResult with the given array of landmarks, blendshapes, facialTransformationMatrixes and timestamp (in milliseconds).

  Declaration

  Objective-C

  - (nonnull instancetype)
             initWithFaceLandmarks:
                 (nonnull NSArray<NSArray<MPPNormalizedLandmark *> *> *)
                     faceLandmarks
                   faceBlendshapes:
                       (nonnull NSArray<MPPClassifications *> *)faceBlendshapes
      facialTransformationMatrixes:
          (nonnull NSArray<MPPTransformMatrix *> *)facialTransformationMatrixes
           timestampInMilliseconds:(NSInteger)timestampInMilliseconds;

  Parameters

  faceLandmarks	An array of NormalizedLandmark objects.
  faceBlendshapes	An array of Classifications objects.
  facialTransformationMatrixes	An array of flattended matrices.
  timestampInMilliseconds	The timestamp (in milliseconds) for this result.

  Return Value

  An instance of FaceLandmarkerResult initialized with the given array of detections and timestamp (in milliseconds).
