Background modeling from a stationary camera is a crucial component in video surveillance. Traditional methods usually adopt single feature type to solve the problem, while the performance is usually unsatisfactory when handling complex scenes. In this paper, we propose a multi-scale strategy, which combines both texture and color features, to achieve a robust and accurate solution. Our contributions...
Background modeling is a fundamental yet challenging issue in video surveillance. Traditional methods usually adopt single feature type to solve the problem, while the performance is usually unsatisfactory when handling complex scenes. In this paper, we propose a multi-scale framework, which combines both texture and intensity feature, to achieve a robust and accurate solution. Our contributions are...
To meet the requirements of some intelligent vehicle monitoring system, the software integrates Global Position System (GPS), Geographic Information System (GIS) and Global System for Mobile communications (GSM) in the whole. The structure, network topology, functions, main technical features and their implementation principles of the system are introduced. Then hardware design of the vehicle terminal...
This paper proposes an adaptive controller for a free-floating space robot (FFSR) in the presence of kinematic and dynamic model uncertainties. Because of high dynamical coupling between the actively operated manipulator and the free-floating base, two inherent difficulties exist, such as non-linear parameterization of the dynamic equation and both kinematic and dynamic parameter uncertainties. In...
This paper proposes an adaptive controller for a free-floating space robot (FFSR) in the presence of friction, disturbance and variation of payload based on robust fuzzy compensator. In the micro-gravity environment, the FFSR lacks a fixed base, so the high dynamic coupling between the manipulators and the free-floating base leads to two inherent difficulties, such as non-linear parameterization of...
