↳ | com.google.android.gms.vision.face.Face |
A human face detected in an image or video.
It is important to note that all fields described here are with regards to the image that the detector has processed. Many live apps that process images directly from the camera show the user a mirrored display of the actual image.
All coordinate values are reported as absolute image coordinates. That is, image position (0, 0) represents the upper-left corner of the image.

![]() |
The value that a probability is set to if it was not computed.
Returns the rotation of the face about the vertical axis of the image. Positive euler y is when the face turns toward the right side of the of the image that is being processed.

float |
the rotation of the face about the vertical axis of the image |
Returns the rotation of the face about the axis pointing out of the image. Positive euler z is a counter-clockwise rotation within the image plane.
Returns | |
---|---|
float |
the rotation of the face about the axis pointing out of the image |
Returns the height of the face region in pixels. This is a rough estimate that is likely to be slightly larger than the exact bounds of the face and therefore may include some background.
Returns | |
---|---|
float |
the height of the face in pixels |
Returns the face ID. This can be used to track a Face over multiple Frames
.
Returns | |
---|---|
int |
Returns a value between 0.0 and 1.0 giving a probability that the face's left eye is open.
This returns UNCOMPUTED_PROBABILITY
if the probability was not computed. The
probability is not computed if eye open classification is not enabled via setClassificationType(int)
or the LEFT_EYE
landmark was not
found.
Returns | |
---|---|
float |
the probability for the face's left eye being open |
Returns a value between 0.0 and 1.0 giving a probability that the face's right eye is open.
This returns UNCOMPUTED_PROBABILITY
if the probability was not computed. The
probability is not computed if eye open classification is not enabled via setClassificationType(int)
or the RIGHT_EYE
landmark was not
found.
Returns | |
---|---|
float |
the probability for the face's right eye being open |
Returns a value between 0.0 and 1.0 giving a probability that the face is smiling.
This returns UNCOMPUTED_PROBABILITY
if the probability was not computed. The
probability is not computed if smile classification is not enabled via setClassificationType(int)
or the required landmarks are not found. The LEFT_MOUTH
, RIGHT_MOUTH
, and NOSE_BASE
landmarks
are required to compute a smile probability.
Returns | |
---|---|
float |
the probability that the face is smiling |
Returns a list of Landmarks
(eyes, nose, etc.) found on the face. A landmark
detector must be specified via setLandmarkType(int)
to detect
landmarks. The landmark detector may not find all possible landmarks on any given face.
Returns | |
---|---|
List<Landmark> |
a list of landmarks found on the face |
Returns the top left position of the face within the image.
Returns | |
---|---|
PointF |
Returns the width of the face region in pixels. This is a rough estimate that is likely to be slightly larger than the exact bounds of the face and therefore may include some background.
Returns | |
---|---|
float |
the width of the face in pixels |
