Amazonka.Rekognition.RecognizeCelebrities
Description
Returns an array of celebrities recognized in the input image. For more information, see Recognizing celebrities in the Amazon Rekognition Developer Guide.
RecognizeCelebrities returns the 64 largest faces in the image. It
lists the recognized celebrities in the CelebrityFaces array and any
unrecognized faces in the UnrecognizedFaces array.
RecognizeCelebrities doesn't return celebrities whose faces aren't
among the largest 64 faces in the image.
For each celebrity recognized, RecognizeCelebrities returns a
Celebrity object. The Celebrity object contains the celebrity name,
ID, URL links to additional information, match confidence, and a
ComparedFace object that you can use to locate the celebrity's face
on the image.
Amazon Rekognition doesn't retain information about which images a
celebrity has been recognized in. Your application must store this
information and use the Celebrity ID property as a unique identifier
for the celebrity. If you don't store the celebrity name or additional
information URLs returned by RecognizeCelebrities, you will need the
ID to identify the celebrity in a call to the GetCelebrityInfo
operation.
You pass the input image either as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes is not supported. The image must be either a PNG or JPEG formatted file.
For an example, see Recognizing celebrities in an image in the Amazon Rekognition Developer Guide.
This operation requires permissions to perform the
rekognition:RecognizeCelebrities operation.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:celebrityFaces:RecognizeCelebritiesResponse', recognizeCelebritiesResponse_celebrityFaces - Details about each celebrity found in the image. Amazon Rekognition can
detect a maximum of 64 celebrities in an image. Each celebrity object
includes the following attributes: Face, Confidence, Emotions,
Landmarks, Pose, Quality, Smile, Id, KnownGender,
MatchConfidence, Name, Urls.
$sel:orientationCorrection:RecognizeCelebritiesResponse', recognizeCelebritiesResponse_orientationCorrection - Support for estimating image orientation using the the
OrientationCorrection field has ceased as of August 2021. Any returned
values for this field included in an API response will always be NULL.
The orientation of the input image (counterclockwise direction). If your
application displays the image, you can use this value to correct the
orientation. The bounding box coordinates returned in CelebrityFaces
and UnrecognizedFaces represent face locations before the image
orientation is corrected.
If the input image is in .jpeg format, it might contain exchangeable
image (Exif) metadata that includes the image's orientation. If so, and
the Exif metadata for the input image populates the orientation field,
the value of OrientationCorrection is null. The CelebrityFaces and
UnrecognizedFaces bounding box coordinates represent face locations
after Exif metadata is used to correct the image orientation. Images in
.png format don't contain Exif metadata.
$sel:unrecognizedFaces:RecognizeCelebritiesResponse', recognizeCelebritiesResponse_unrecognizedFaces - Details about each unrecognized face in the image.
$sel:httpStatus:RecognizeCelebritiesResponse', recognizeCelebritiesResponse_httpStatus - The response's http status code.
