Optional
AttributesAn array of facial attributes you want to be returned. A DEFAULT
subset of
facial attributes - BoundingBox
, Confidence
, Pose
,
Quality
, and Landmarks
- will always be returned. You can request
for specific facial attributes (in addition to the default list) - by using ["DEFAULT",
"FACE_OCCLUDED"
] or just ["FACE_OCCLUDED"
]. You can request for all
facial attributes by using ["ALL"]
. Requesting more attributes may increase
response time.
If you provide both, ["ALL", "DEFAULT"]
, the service uses a logical "AND"
operator to determine which attributes to return (in this case, all attributes).
Note that while the FaceOccluded and EyeDirection attributes are supported when using
DetectFaces
, they aren't supported when analyzing videos with
StartFaceDetection
and GetFaceDetection
.
The input image as base64-encoded bytes or an S3 object. If you use the AWS CLI to call Amazon Rekognition operations, passing base64-encoded image bytes is not supported.
If you are using an AWS SDK to call Amazon Rekognition, you might not need to
base64-encode image bytes passed using the Bytes
field. For more information, see
Images in the Amazon Rekognition developer guide.
