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.

Comparing withHayek's theory on society method, I believe constitution litigationmechanism must considering the following conclusion in modelingconstitutional method: first, the acquiring of constitutional method isusually effects system vicissitudes. Although constitutional arbitramentcan form definite constitutional method, it can't achieve perduringsubstantial results level of method; secondly, constitutional method isformed virtually by the mixture of two kind of potence, and one is socialpotence, the other is governmental potence. The constitutional method'srationality in logic structure rests directly with the wrestling process ofconstitutional logic and social process. Constitutional method is more akind of simulative conformation of natural logic and social logic, itforms by the wrestling of government, public, legislature andconstitution judging organ. Fourthly, the maintenance of constitutionalmethod depends on the inner power sustained by faith and exteriorpower coming from the background of compulsion. Fifthly,constitutional method itself is a dynamic structure, and it's realizingquomodo and vindicating means is being in vicissitude, however, it canonly provide condition and inspiritment.

对照哈耶克的社会秩序理论，笔者认为，宪法诉讼机制在型构宪政秩序时必然要照顾到以下结论：其一，宪政秩序的取得，往往是一个制度自然变迁的结果，宪法裁决虽然也可能在短期内形成一定的宪法秩序，不过却无法强行地达到一个较大范围内持久的秩序实效水准；其二，宪政秩序实际上是由两种力量交合而成的，一是社会力量，一是政府力量，宪政秩序的逻辑结构的合理性直接取决于宪法逻辑和社会逻辑之间的博弈过程；其三，宪政秩序更多的是一种对自然逻辑和社会逻辑的模拟形态，是经由政府、公众、立法机关与宪法裁判机构的合作博弈而形成的，宪法诉讼的功用至多在于提供博弈规则，以实现纳什均衡；其四，宪政秩序的维护主要依靠来自信念支持的内部力量与来自强制背景的外部力量；其五，宪政秩序本身是一个动态的、常新的结构，其实现方式与维护手段也处于不断变迁之中，但无论如何，宪法诉讼机制所能提供的只是制约与激励两种。
