PASSIVE VISUAL MONITORING: MOVING OBJECTS COME FROM HUMAN ENTITIES

The various visual sensors allows the detection and observation of various human activities in different environments. From the terrestrial activities to the maritime activities, the visual sensors allow researchers to detect, track and recognize human activities.

A) Terrestrial Entities

• Humans :  

• Vehicles:

B) Marine Entities

• Boats surveillance can be achieved in visible spectrum or IR spectrum . The idea is to count, to track and to recognize boats in fluvial canals, in river, or in open sea.

C) Aerial Entities

• Airport visual surveillance mainly concerns the area where aircrafts are parked and maintained by specialized ground vehicles such as fueling vehicles and baggage cars as well as tracking of individuals such as workers. The need of visual surveillance is given due to the following reasons: (1) an airports apron is a security relevant area, (2) it helps to improve transit time, i.e. the time the aircraft is parking on the apron, and (3) it helps to minimize costs for the company operating the airport, as personal can be deployed more efficiently,and to minimize latencies for the passengers, as the time needed for accomplishing ground services decreases.
