Response fields

Field	Type	Meaning
`faceCount`	number	Number of detected faces.
`faces[].boundingBox`	object	Face location as ratios of image width and height, measured from the top-left.
`faces[].detectionConfidence`	number	Face detection confidence.
`faces[].sharpness / brightness`	number	Image quality measurements for the face region, from 0 to 100.
`faces[].pitch / roll / yaw`	number	Head pose angles in degrees.
`faces[].ageLow / ageHigh`	number	An estimated age range, not a verified age.
`faces[].gender / emotions`	estimates	Model predictions with confidence scores, not verified personal characteristics or internal emotional states.
`faces[].genderConfidence`	number	Confidence in the gender prediction, from 0 to 100.
`faces[].smile / eyeglasses / sunglasses`	boolean	Detected visible traits.
`faces[].beard / mustache`	boolean	Detected facial-hair traits.
`faces[].eyesOpen / mouthOpen`	boolean	Detected eye and mouth state.
`faces[].emotions[]`	array	Predicted emotion labels with type and confidence, most-confident first.

Interpreting the result

Use image-quality and pose signals to guide better image capture. Estimated attributes should not be treated as verified facts about a person.
