We propose a method which can be used to perform real-time tracking of moving vehicles on highways. In addition to tracking regular cars, the proposed method can also track a vehicle performing a lane change. The proposed method consists of two sections: a detection and a tracking. In the detection section, we use entropy-based features to check for the existence of vehicles. Then, we perform tracking based on the entropy features derived in the detection section. By conducting a great number of experiments, we have demonstrated the efficiency as well as the effectiveness of the proposed system.

Keywords: intelligent transportation system, entropy, real-time, vehicle tracking, surveillance system
