VisionFace

class VisionFace : NSObject

A human face detected in an image.

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

    Declaration

    Swift

    var frame: CGRect { get }
  • Indicates whether the face has a tracking ID.

    Declaration

    Swift

    var hasTrackingID: Bool { get }
  • The tracking identifier of the face.

    Declaration

    Swift

    var trackingID: Int { get }
  • Indicates whether the detector found the head y euler angle.

    Declaration

    Swift

    var hasHeadEulerAngleY: Bool { get }
  • Indicates the rotation of the face about the vertical axis of the image. Positive y euler angle is when the face is turned towards the right side of the image that is being processed.

    Declaration

    Swift

    var headEulerAngleY: CGFloat { get }
  • Indicates whether the detector found the head z euler angle.

    Declaration

    Swift

    var hasHeadEulerAngleZ: Bool { get }
  • Indicates the rotation of the face about the axis pointing out of the image. Positive z euler angle is a counter-clockwise rotation within the image plane.

    Declaration

    Swift

    var headEulerAngleZ: CGFloat { get }
  • Indicates whether a smiling probability is available.

    Declaration

    Swift

    var hasSmilingProbability: Bool { get }
  • Probability that the face is smiling.

    Declaration

    Swift

    var smilingProbability: CGFloat { get }
  • Indicates whether a left eye open probability is available.

    Declaration

    Swift

    var hasLeftEyeOpenProbability: Bool { get }
  • Probability that the face’s left eye is open.

    Declaration

    Swift

    var leftEyeOpenProbability: CGFloat { get }
  • Indicates whether a right eye open probability is available.

    Declaration

    Swift

    var hasRightEyeOpenProbability: Bool { get }
  • Probability that the face’s right eye is open.

    Declaration

    Swift

    var rightEyeOpenProbability: CGFloat { get }
  • Unavailable.

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

    Declaration

    Swift

    func landmark(ofType type: 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

    func contour(ofType type: 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.
