Gets the face search results for Amazon Rekognition Video face search started by
StartFaceSearch. The search returns faces in a collection that match the faces of persons detected in a video. It also includes the time(s) that faces are matched in the video.
Face search in a video is an asynchronous operation. You start face search by calling to
StartFaceSearch which returns a job identifier (
JobId
). When the search operation finishes, Amazon Rekognition Video publishes a completion status to the Amazon Simple Notification Service topic registered in the initial call to
StartFaceSearch
. To get the search results, first check that the status value published to the Amazon SNS topic is
SUCCEEDED
. If so, call
GetFaceSearch
and pass the job identifier (
JobId
) from the initial call to
StartFaceSearch
.
For more information, see Searching Faces in a Collection in the Amazon Rekognition Developer Guide.
The search results are retured in an array,
Persons
, of
PersonMatch objects. Each
PersonMatch
element contains details about the matching faces in the input collection, person information (facial attributes, bounding boxes, and person identifer) for the matched person, and the time the person was matched in the video.
GetFaceSearch
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
Persons
array is sorted by the time, in milliseconds from the start of the video, persons are matched. You can also sort by persons by specifying
INDEX
for the
SORTBY
input parameter.
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.
