FirebaseMLVision Framework Reference

VisionFace

classVisionFace:NSObject

A human face detected in an image.

  • The rectangle that holds the discovered relative to the detected image in the viewcoordinate system.

    Declaration

    Swift

    varframe:CGRect{get}

  • Indicates whether the face has a tracking ID.

    Declaration

    Swift

    varhasTrackingID:Bool{get}

  • The tracking identifier of the face.

    Declaration

    Swift

    vartrackingID:Int{get}

  • Indicates whether the detector found the head y euler angle.

    Declaration

    Swift

    varhasHeadEulerAngleY:Bool{get}

  • Indicates the rotation of the face about the vertical axis of the image. Positive y euler angleis when the face is turned towards the right side of the image that is being processed.

    Declaration

    Swift

    varheadEulerAngleY:CGFloat{get}

  • Indicates whether the detector found the head z euler angle.

    Declaration

    Swift

    varhasHeadEulerAngleZ:Bool{get}

  • Indicates the rotation of the face about the axis pointing out of the image. Positive z eulerangle is a counter-clockwise rotation within the image plane.

    Declaration

    Swift

    varheadEulerAngleZ:CGFloat{get}

  • Indicates whether a smiling probability is available.

    Declaration

    Swift

    varhasSmilingProbability:Bool{get}

  • Probability that the face is smiling.

    Declaration

    Swift

    varsmilingProbability:CGFloat{get}

  • Indicates whether a left eye open probability is available.

    Declaration

    Swift

    varhasLeftEyeOpenProbability:Bool{get}

  • Probability that the face’s left eye is open.

    Declaration

    Swift

    varleftEyeOpenProbability:CGFloat{get}

  • Indicates whether a right eye open probability is available.

    Declaration

    Swift

    varhasRightEyeOpenProbability:Bool{get}

  • Probability that the face’s right eye is open.

    Declaration

    Swift

    varrightEyeOpenProbability:CGFloat{get}

  • Unavailable.

  • Returns the landmark, if any, of the given type in this detected face.

    Declaration

    Swift

    funclandmark(ofTypetype:FaceLandmarkType)->VisionFaceLandmark?

    Parameters

    type

    The type of the facial landmark.

    Return Value

    The landmark of the given type in this face.nil if there isn’t one.

  • Returns the contour, if any, of the given type in this detected face.

    Declaration

    Swift

    funccontour(ofTypetype:FaceContourType)->VisionFaceContour?

    Parameters

    type

    The type of the facial contour.

    Return Value

    The contour of the given type in this face.nil if there isn’t one.
