ROS image  for airport

B: ROS

Passengers moving from the entrance point straight toward an aeroplane one after another. In A, each time a new passenger is found in the entrance area, he will be registered and tracked until he reaches the aeroplane. B is the corresponding video showing Regions of Significance. 2

Bag Exchanging

A: Bag Exchanging

ROS image  for bag exchanging

B: ROS

Bag exchanging sequence. In A, Person 3 (red bounding box) comes into the lobby where Person 1 (yellow bounding box) and Person 2 (green bounding box) are sitting in. Person 2 gets up, leaves a bag in the scene and leaves the scene. Person 1 leaves the scene without picking up the bag. Person 3 gets up, picks the bag and leaves. Each solid rectangle in the upper-left corner shows the tracking status of the corresponding object of interest, including 'tracked', 'lost' and 'disappeared'. B is the corresponding video showing Regions of Significance.
