// Service topic registered in the initial call to StartPersonTracking.
//
// To get the results of the person path tracking operation, first check that
// the status value published to the Amazon SNS topic is SUCCEEDED. If so, call
// GetPersonTracking and pass the job identifier (JobId) from the initial call
// to StartPersonTracking.
//
// GetPersonTracking returns an array, Persons, of tracked persons and the time(s)
// their paths were tracked in the video.
//
// GetPersonTracking 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 array is sorted by the time(s) a person's path is tracked
// in the video. You can sort by tracked persons by specifying INDEX for the
// SortBy input parameter.
//
// Use the MaxResults parameter to limit the number of items 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 GetPersonTracking and populate
// the NextToken request parameter with the token value returned from the previous
// call to GetPersonTracking.
