查询词典 finit element method

To declare what we can do with a set, we start a header file Set.h:#ifndef SET_H #define SET_H extern const void * Set; void * add (void * set, const void * element); void * find (const void * set, const void * element); void * drop (void * set, const void * element); int contains (const void * set, const void * element);#endif The preprocessor statements protect the declarations: no matter how many times we include Set.h, the C compiler only sees the declarations once.

宣布我们能做些什么用一套，我们开始一个头文件Set.h ：＃ ifndef SET_H ＃定义SET_H 外部构造无效*设置；无效*地址（无效*一套，无效*常量元素）；无效*找到（常量无效*一套，无效*常量元素）；无效*下降（无效*一套，无效*常量元素）；国际载（常量无效*一套，无效*常量元素）；＃ endif 预报表保护声明：无论多少次我们包括Set.h ， C编译器将只看到申报一次。

In this paper, the theory, algorithm, and experiment of automatic object detection and tracking are studied in depth. It is firstly pointed out that the essential of Mean Shift method is a special Newton-Gaussian method. A new method named Fast Mean Shift is established to stretch the conservative step of Mean Shift method. The convergence and validity of this new method are proved in theory. And it is also proved that the convergence speed of Fast Mean Shift is faster than that of Mean Shift. The contrast experiments of searching the maximum possibility density of random of data sets in plane and 3D space are done. The results show that this new method can reduce the iterations greatly. A new object tracking method based on Fast Mean Shift is built to improve the object tracking performance, which is shown in the face tracking experiment with the tennis sequence provided by the Ohio State University, and the car tracking experiment with the car sequence provided by Kalsruhe University. The face trcking experiment with highly noised images show that the object tracking method based on Fast Mean Shift has strong anti-jamming ability. A new fast color object detection technology based on characteristic color is established, which use characteristic color distribution to compute the characteristic color vector of any area in an image quickly. With the high performance search method, the fast object detection is achieved. At last, using object tracker based on Fast Mean Shift and color object detector based on characteristic color with the Kalman filter, PID controller, searial communication and other technologies, automatic object detection and tracking system with control system is built. The availability and anti-jamming ability of this system are verified by some object detection and tracking tests in different scenes.
