Gets the path tracking results of a Amazon Rekognition Video analysis started by StartPersonTracking.
The person path tracking operation is started by a call to StartPersonTracking
which returns a job identifier (JobId
). When the operation finishes, Amazon
Rekognition Video publishes a completion status to the Amazon Simple Notification
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
.
For .NET Core this operation is only available in asynchronous form. Please refer to GetPersonTrackingAsync.
