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.

I don't understand how people get away with this (another related sin involves the complete misrepresentation of the political philosophy of John Rawls, something of which de Waal is often guilty): it's extraordinarily sloppy, and basically the equivalent of writing that Newton's Law of Gravitation says that every action has a reaction.

其错误在于将其论断性误认为确定性（更多了解，登陆 http：//plato.stanford.edu/entries/moore-moral/）我不知道人们是如何免受其责的（另一个相关的错误涉及对 John Rawls 的政治哲学的完全误传，这方面 de Waal 也常有责任）：这太随便了，基本上相当于牛顿力学的力必然产生反作用力。
