--
-- 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. This CelebrityDetail object stores information
-- about the detected celebrity\'s face attributes, a face bounding box,
-- known gender, the celebrity\'s name, and a confidence estimate.
--
-- @GetCelebrityRecognition@ only returns the default facial attributes
-- (@BoundingBox@, @Confidence@, @Landmarks@, @Pose@, and @Quality@). The
-- @BoundingBox@ field only applies to the detected face instance. 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@.
