As a common scheme of image tampering, copy-move forgery plays an important role in image forgery committee. Although several blind methods aimed at detecting replicated regions have been proposed, these methods cannot detect the rotation changes in the duplicated areas efficiently. In this paper, a new forensic method is presented to detect the replicated(More)
For flight motion simulator servo system, this paper presents a kind of robust discrete sliding mode controller based on disturbance observer. The entire system is composed of two parts: one is the design of disturbance observer and the other is the design of discrete sliding mode controller. Sliding mode controller (SMC) is a special nonlinear control(More)
This paper studies the design of a wireless data acquisition system applied in greenhouse by building a wireless sensor network based on ZigBee. The system includes acquisiton terminals, routing nodes, an ethernet gateway and a server. The terminals are solar powered with no external power supply, which can be flexibly deployed. Through multiple sensors(More)
In this paper, a novel servo turning table control method based on optimal fuzzy reasoning and disturbance observer (DOB) was studied. Optimal fuzzy reasoning contains thought of optimization and feedback, and a fuzzy-PID controller using optimal fuzzy reasoning can make the reasoning process more reasonable and enhance the robustness to some extent.(More)
Aiming at the data set expressed by decision-list, proposed an algorithm of optimum decision rules discovery based on granule computing. It increased the efficiency of decision rules mining by two ways, improving speed of getting frequent item sets with granule computing and deleting invalid candidate sets. Finally the result of calculating test showed the(More)
A parallel controller was designed in order to realize an industry robot steady control performance. On the base of robust backstepping technique, a method for parallel control of robust backstepping and CMAC neural network was proposed for industry robot. It consisted of a robust controller designed through backstepping method and a CMAC controller. The(More)
