Gets face detection results for a Amazon Rekognition Video analysis started by
StartFaceDetection.
Face detection with Amazon Rekognition Video is an asynchronous operation. You start face detection by calling
StartFaceDetection which returns a job identifier (
JobId). When the face detection operation finishes, Amazon Rekognition Video publishes a completion status to the Amazon Simple Notification Service topic registered in the initial call to
StartFaceDetection. To get the results of the face detection operation, first check that the status value published to the Amazon SNS topic is
SUCCEEDED. If so, call
GetFaceDetection and pass the job identifier (
JobId) from the initial call to
StartFaceDetection.
GetFaceDetection returns an array of detected faces (
Faces) sorted by the time the faces were detected.
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
GetFaceDetection and populate the
NextToken request parameter with the token value returned from the previous call to
GetFaceDetection.
Note that for the
GetFaceDetection operation, the returned values for
FaceOccluded and
EyeDirection will always be "null".
In the AWS.Tools.Rekognition module, this cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.
