Chapter 1 briefs the relation between invariance and computer vision and summarizes the research and application of invariance in computer vision. Chapter 2 first derives the transformations of three camera models, then makes the correpondences between the models and three typical geometrical transformation groups by analysing the transformations respectively. The correspondences supply the theoretical basis for applying geometrical invariants to resolve the problems of computer vision. In Chapter 3, we describe the geometrical invariant theory and prove some geometrical invariants of coplanar points, lines or conics by algebraic method. In order to use the invariants of conic pairs to describe general 2D shapes, we discuss the perspectively invariant representation of planar curves using conies in detail. A system consisted of two TMS320C25 and based on moment invariants is introduced in Chapter 5. The system can recognize more than 30 different shapes of object model or more than 10 plane models with similar shape in real time.

第一章简述了不变性与计算机视觉的关系，以及计算机视觉中的不变性研究和应用概况；第二章推导了计算机视觉中常用三种投影模型的变换关系，通过对这三种变换关系的分析，分别建立了这三种投影模型和几何学中的三种变换群之间的一一对应关系，为几何不变性在计算机视觉中的应用提供了理论基础；在第三章中，我们介绍了几何不变性的理论，并且用代数方法证明了共面点、直线、二次曲线的几何不变量和射影不变量；为了把二次曲线的不变量用于一般二维形状描述，在第四章中我们详细地讨论了用二次曲线实现一般平面曲线的透视不变性表示的方法；第五章介绍了用两片TMS320C25构成的、基于不变矩形特征的运动目标实时识别系统。

The finite nonabelian simple group PSL(2,23) has the minimum degree 506 GR of connected cubic arc-transitive coset graphs.

First, two preprocess algorithms are designed to decompose a communication request set into some continuous cyclic sequences. Then the permutation group is used to represent the ring network with fixed converters and an algorithm is proposed to classify the wavelength channels into some groups.Based on these on these ideas,a wavelength assignment algorithm is presented.For an optical ring with any fixed conversion mode,the algorithm can giv a good assignment scheme.

首先，提出了两个对环网上的请求集合预处理的算法，这两个算法可以将请求集合分解成一些连续的循环序列；然后，采用置换群来描述具有固定波长转换器的光环网，基于这种数学表示，提出了对环网上的波长信道进行分解的算法；基于这些算法，进一步提出了一个波长分配算法，该算法对于环形光网上的任意固定转换模式都能给出一个较好的波长分配方案。

First, the individuals who would be most likely to benefit need to be identified, writes editorialist Sanford Markowitz, MD, PhD, from Case Western Reserve University, in Cleveland, Ohio. Then, it needs to be shown that certain persons reproducibly demonstrate high COX-2 expression in independent adenomas or cancers, because of genetic predisposition or environmental exposures. And third, the work of Dr. Chan and colleagues needs to be extended by demonstrating that prevention of colon adenomas by aspirin or COX-2 inhibitors also involves blocking the development of the highest COX-2–expressing lesions, he says.

俄亥俄州克里夫兰Case Western Reserve大学的Case Western Reserve医师表示，首先，必须要拿找出最能受益的一群病患；接著，必须要能证实部分病患的独立腺瘤或癌症，因为基因及环境的影响，会一再地是高度表现COX-2的；第三，Chan医师与其同事的研究，需要透过aspirin或是COX-2抑制剂可以预防大肠腺瘤的作用，也牵涉到阻断COX-2表现病灶的生成。
