Network.AWS.Rekognition.GetPersonTracking

Gets the person tracking results of a Rekognition Video analysis started by .

The person detection operation is started by a call to StartPersonTracking which returns a job identifier (JobId ). When the person detection operation finishes, 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 tracking operation, first check that the status value published to the Amazon SNS topic is SUCCEEDED . If so, call and pass the job identifier (JobId ) from the initial call to StartPersonTracking .

GetPersonTracking returns an array, Persons , of tracked persons and the time(s) they were tracked in the video.

By default, the array is sorted by the time(s) a person 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 .

Creating a Request

getPersonTracking

Arguments

:: Text

gptJobId

-> GetPersonTracking

Creates a value of GetPersonTracking with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• gptNextToken - If the previous response was incomplete (because there are more persons to retrieve), Rekognition Video returns a pagination token in the response. You can use this pagination token to retrieve the next set of persons.
• gptMaxResults - Maximum number of results to return per paginated call. The largest value you can specify is 1000. If you specify a value greater than 1000, a maximum of 1000 results is returned. The default value is 1000.
• gptSortBy - Sort to use for elements in the Persons array. Use TIMESTAMP to sort array elements by the time persons are detected. Use INDEX to sort by the tracked persons. If you sort by INDEX , the array elements for each person are sorted by detection confidence. The default sort is by TIMESTAMP .
• gptJobId - The identifier for a job that tracks persons in a video. You get the JobId from a call to StartPersonTracking .

Request Lenses

gptNextToken :: Lens' GetPersonTracking (Maybe Text)

If the previous response was incomplete (because there are more persons to retrieve), Rekognition Video returns a pagination token in the response. You can use this pagination token to retrieve the next set of persons.

gptMaxResults :: Lens' GetPersonTracking (Maybe Natural)

Maximum number of results to return per paginated call. The largest value you can specify is 1000. If you specify a value greater than 1000, a maximum of 1000 results is returned. The default value is 1000.

gptSortBy :: Lens' GetPersonTracking (Maybe PersonTrackingSortBy)

Sort to use for elements in the Persons array. Use TIMESTAMP to sort array elements by the time persons are detected. Use INDEX to sort by the tracked persons. If you sort by INDEX , the array elements for each person are sorted by detection confidence. The default sort is by TIMESTAMP .

gptJobId :: Lens' GetPersonTracking Text

The identifier for a job that tracks persons in a video. You get the JobId from a call to StartPersonTracking .

Destructuring the Response
