FIRVisionFace

@interfaceFIRVisionFace:NSObject

A human face detected in an image.

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

    Declaration

    Objective-C

    @property(nonatomic,readonly)CGRectframe;

  • Indicates whether the face has a tracking ID.

    Declaration

    Objective-C

    @property(nonatomic,readonly)BOOLhasTrackingID;

  • The tracking identifier of the face.

    Declaration

    Objective-C

    @property(nonatomic,readonly)NSIntegertrackingID;

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

    Declaration

    Objective-C

    @property(nonatomic,readonly)BOOLhasHeadEulerAngleY;

  • 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

    Objective-C

    @property(nonatomic,readonly)CGFloatheadEulerAngleY;

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

    Declaration

    Objective-C

    @property(nonatomic,readonly)BOOLhasHeadEulerAngleZ;

  • 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

    Objective-C

    @property(nonatomic,readonly)CGFloatheadEulerAngleZ;

  • Indicates whether a smiling probability is available.

    Declaration

    Objective-C

    @property(nonatomic,readonly)BOOLhasSmilingProbability;

  • Probability that the face is smiling.

    Declaration

    Objective-C

    @property(nonatomic,readonly)CGFloatsmilingProbability;

  • Indicates whether a left eye open probability is available.

    Declaration

    Objective-C

    @property(nonatomic,readonly)BOOLhasLeftEyeOpenProbability;

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

    Declaration

    Objective-C

    @property(nonatomic,readonly)CGFloatleftEyeOpenProbability;

  • Indicates whether a right eye open probability is available.

    Declaration

    Objective-C

    @property(nonatomic,readonly)BOOLhasRightEyeOpenProbability;

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

    Declaration

    Objective-C

    @property(nonatomic,readonly)CGFloatrightEyeOpenProbability;

  • Unavailable.

    Declaration

    Objective-C

    -(nonnullinstancetype)init;

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

    Declaration

    Objective-C

    -(nullableFIRVisionFaceLandmark*)landmarkOfType:(nonnullFIRFaceLandmarkType)type;

    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

    Objective-C

    -(nullableFIRVisionFaceContour*)contourOfType:(nonnullFIRFaceContourType)type;

    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.
