GetCelebrityRecognition
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.
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.
Note
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.
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
.
