An object tracking algorithm based on SURF is presented in this *** points are detected by SURF detector in reference region which is located in the first frame *** the following sequences,the SURF feature points are extracted in a larger window which is selected as test *** the matching stage,we calculate the Euclidean distance between the descriptor vectors of interest points in the test image and ones in the reference *** proposed algorithm is implemented on an embedded platform with TI's DM6446 high performance *** experimental results show that our system implements a real-time tracking with robustness against appearance variations,scale change,and cluttered scenes.
In this paper, A simple and effective mechanism is proposed to realize the parsimoniousness of the online least squares support vector machine. Hence, the response time is curtailed. Besides, a modified Particle Swarm...

An improved included angle dividing method is proposed for Hammerstein systems. In this dividing method, nonlinearity of the system is taken into account to distribute gridding points, so distribution is more reasonable and computation load in dividing is reduced largely. Based on the dividing result, a multimodel predictive controller is designed to overcome the drawbacks of the common nonlinearity inversion control method for Hammerstein systems.
This paper is concerned with identification of linear parameter varying (LPV) systems in an input-output setting with Box-Jenkins (BJ) model structure. Classical linear time invariant prediction error method (PEM) is ...

Based on Lyapunov stability theorem, a MRAC system was researched to solve that differential value of plant output is unknown. Meanwhile an improved design for MRAC system aimed on the factor of restricting convergence of system is given. The method not only solves the problem that makes the system can not work well as a result of the adjustable parameters, but also improves the convergence of plant. The simulation graphs have shown that the plant can follow the output of the reference model quit well
