This method represents the virtual objects in Euclidean space instead of in affine space, which is consistent with the popular graphics rendering tools such as OpenGL and is more common in practice. A new classification based local and global tracking strategy to match features between the reference image and the currently frame directly is presented, which enables the augmented reality system working effectively even under large changes of viewing angles. A novel affine coordinate system definition method based on a collection of feature points is also proposed, which makes the tracking method effective even when not all the reference points are detected during the whole process, as long as there are at least four pairs of reference points correspondences.

该方法以仿射变换为桥梁来建立欧氏空间下的摄像机坐标系与世界坐标系之间的变换关系，它与OpenGL等当前流行的图形渲染工具一致，具有更强的通用性；采用基于分类的自然特征匹配策略，能够在视角和视点发生大幅度变化情况下依然正常工作；提出基于特征点集合的仿射坐标系定义方法，使增强现实系统在最小配置下只需4点追踪成功即可完成注册，比需要6点的透视投影方法具有更好的健壮性和精确性。

As the most of traditional Intrusion Detection Systems are static and have difficulty in coordinating with the outer dynamic situation, consequently, leading to a serial of deficiency such as limited distribution .limited accommodation and limited robust etc. Fortunately, the Human Immune System can protect themselves from the invasion of the virus, germina and all such sort of things. Meanwhile, they has a lot of excellent features such as good distribution, Self-organization,dynamic and so on and these features perform fabulous similarity on the function and characteristic with the Intrusion Detection System,which arousing peoples highly attention and interesting and make the researching and development of the Intrusion Detection System based Human Immune System becoming one of the hot and the key of the network security research.

由于传统的入侵检测系统大多是静态的，很难与动态环境协调一致，造成分布性差，适应性差，健壮性不好等种种缺陷；而生物免疫系统可以保护人类机体不受诸如病毒，病菌等各种病原体的侵害，且表现出了分布式保护，多样性，自组织性，动态性等良好特性，且这种与入侵检测系统在功能和特性上的惊人相似，引起人们的高度重视和兴趣，使得借鉴生物免疫系统的机理开发研究入侵检测系统成为网络安全的研究热点和重点。

与ANSYS的子空间迭代和Lanczos法相比，本文的子空间迭代比ANSYS的效率高很多，Lanczos法和ANSYS的效率差不多。大量较大规模的例题显示，本文对特征值算法的改进是十分有效的，算法的健壮性，通用性都达到了高水平。

Finally, the programme of design for routing protocols is chose in the thesis. Secondly, improved algorithms are introduced in detail. In order to achieve to reduce duplication of data sent in, save energy, prolong the network lifetime and balance the network load, improved algorithms are based on the minimum hops algorithm which is one of the energy-aware routing, When the characters of the minimum hops algorithm are analysed in detail,multi-path routing, adaptive dynamic routing, routing reliability are designed.Then a new algorithm based on minimum hops in plane routing protocol and a new algorithm based on minimum hops in clustering routing protocol are designed in the thesis.
