Analyzes the drone's life video feed and applies computer vision technology to track a face or a person. Allows Tello to follow a person, a face, or an arbitrary object, or to fly a circle around an object. Works with the Ryze Tello EDU, Tello Iron Man Edition, and standard Tello drone. Totally calm weather is required for outdoor use! Only videos and no photos supported as Tello firmware has a bug that causes loss of image stabilization when taking photos. The recorded video is the unprocessed stream coming from Tello, it has Keyframes only every 7 seconds so when using time slider on replay you will see glitches.
