// 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
