-- publishes the object detection results and completion status of a video
-- analysis operation.

-- Amazon Rekognition publishes a notification the first time an object of
-- interest or a person is detected in the video stream. For example, if
-- Amazon Rekognition detects a person at second 2, a pet at second 4, and
-- a person again at second 5, Amazon Rekognition sends 2 object class
-- detected notifications, one for a person at second 2 and one for a pet
-- at second 4.
--
-- Amazon Rekognition also publishes an an end-of-session notification with
-- a summary when the stream processing session is complete.
