Class FaceAnnotation (2.0.0) 

FaceAnnotation(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A face annotation object contains the results of face detection.

Attributes

NameDescription
bounding_poly .geometry.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 .geometry.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 Sequence[.image_annotator.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 .image_annotator.Likelihood
Joy likelihood.
sorrow_likelihood .image_annotator.Likelihood
Sorrow likelihood.
anger_likelihood .image_annotator.Likelihood
Anger likelihood.
surprise_likelihood .image_annotator.Likelihood
Surprise likelihood.
under_exposed_likelihood .image_annotator.Likelihood
Under-exposed likelihood.
blurred_likelihood .image_annotator.Likelihood
Blurred likelihood.
headwear_likelihood .image_annotator.Likelihood
Headwear likelihood.

Landmark

Landmark(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A face-specific landmark (for example, a face feature).
