Methods

__construct

Constructor.

Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ bounding_poly	BoundingPoly The bounding polygon around the face. The coordinates of the bounding box are in the original image's scale. The bounding box is computed to "frame" the face in accordance with human expectations. It is based on the landmarker results. Note that one or more x and/or y coordinates may not be generated in the BoundingPoly (the polygon will be unbounded) if only a partial face appears in the image to be annotated.
↳ fd_bounding_poly	BoundingPoly The fd_bounding_poly bounding polygon is tighter than the boundingPoly, and encloses only the skin part of the face. Typically, it is used to eliminate the face from any image analysis that detects the "amount of skin" visible in an image. It is not based on the landmarker results, only on the initial face detection, hence the fd (face detection) prefix.
↳ landmarks	array<FaceAnnotation\Landmark> Detected face landmarks.
↳ roll_angle	float Roll angle, which indicates the amount of clockwise/anti-clockwise rotation of the face relative to the image vertical about the axis perpendicular to the face. Range [-180,180].
↳ pan_angle	float Yaw angle, which indicates the leftward/rightward angle that the face is pointing relative to the vertical plane perpendicular to the image. Range [-180,180].
↳ tilt_angle	float Pitch angle, which indicates the upwards/downwards angle that the face is pointing relative to the image's horizontal plane. Range [-180,180].
↳ detection_confidence	float Detection confidence. Range [0, 1].
↳ landmarking_confidence	float Face landmarking confidence. Range [0, 1].
↳ joy_likelihood	int Joy likelihood.
↳ sorrow_likelihood	int Sorrow likelihood.
↳ anger_likelihood	int Anger likelihood.
↳ surprise_likelihood	int Surprise likelihood.
↳ under_exposed_likelihood	int Under-exposed likelihood.
↳ blurred_likelihood	int Blurred likelihood.
↳ headwear_likelihood	int Headwear likelihood.

getBoundingPoly

The bounding polygon around the face. The coordinates of the bounding box are in the original image's scale.

The bounding box is computed to "frame" the face in accordance with human expectations. It is based on the landmarker results. Note that one or more x and/or y coordinates may not be generated in the BoundingPoly (the polygon will be unbounded) if only a partial face appears in the image to be annotated.

Returns

setBoundingPoly

The bounding box is computed to "frame" the face in accordance with human expectations. It is based on the landmarker results. Note that one or more x and/or y coordinates may not be generated in the BoundingPoly (the polygon will be unbounded) if only a partial face appears in the image to be annotated.
