// Gets the celebrity recognition results for a Amazon Rekognition Video analysis
// started by StartCelebrityRecognition. Celebrity recognition in a video is an
// asynchronous operation. Analysis is started by a call to
// StartCelebrityRecognition which returns a job identifier (JobId). When the
// celebrity recognition operation finishes, Amazon Rekognition Video publishes a
// completion status to the Amazon Simple Notification Service topic registered in
// the initial call to StartCelebrityRecognition. To get the results of the
// celebrity recognition analysis, first check that the status value published to
// the Amazon SNS topic is SUCCEEDED. If so, call GetCelebrityDetection and pass
// the job identifier (JobId) from the initial call to StartCelebrityDetection. For
// more information, see Working With Stored Videos in the Amazon Rekognition
// Developer Guide. GetCelebrityRecognition returns detected celebrities and the
// time(s) they are detected in an array (Celebrities) of CelebrityRecognition
// objects. Each CelebrityRecognition contains information about the celebrity in a
// CelebrityDetail object and the time, Timestamp, the celebrity was detected.
// GetCelebrityRecognition only returns the default
//
// facial attributes
// (BoundingBox, Confidence, Landmarks, Pose, and Quality). The other facial
// attributes listed in the Face object of the following response syntax are not
// returned. For more information, see FaceDetail in the Amazon Rekognition
// Developer Guide. By default, the Celebrities array is sorted by time
// (milliseconds from the start of the video). You can also sort the array by
// celebrity by specifying the value ID in the SortBy input parameter. The
// CelebrityDetail object includes the celebrity identifer and additional
// information urls. If you don't store the additional information urls, you can
// get them later by calling GetCelebrityInfo with the celebrity identifer. No
// information is returned for faces not recognized as celebrities. Use MaxResults
// parameter to limit the number of labels returned. If there are more results than
// specified in MaxResults, the value of NextToken in the operation response
// contains a pagination token for getting the next set of results. To get the next
// page of results, call GetCelebrityDetection and populate the NextToken request
// parameter with the token value returned from the previous call to
// GetCelebrityRecognition.
