Geometric simplification is thus hard to apply when the visual appearance of an object depends on resolving the ordering and mutual occlusion of even very close-by surfaces, potentially with different shading properties.

几何简化因此是难以用于当一个对象的视觉效果取决于解决的顺序与十分靠近表面的相互遮挡，以及不同的着色属性的简化。

The major purpose of this article was to illustrate the innovating instruction of the topic-"triangle" for the third graders. From the experience of the classrooms, it is considered that the curriculum is only to instill into children some geometric nouns, such as the sides, the apexes and the angles. A closed graph with three angles is usually to be named as a triangle without thinking about children's understanding of the real meaning.

本文的主要目的乃是针对教学者本身以往在教国小三年级学童的「三角形」这个单元时，自觉只是在灌输孩子一些几何的名词，例如：这个就是边、顶点和角；有三个角的封闭图形就是三角形，并没有去考虑到孩子是否真正的理解这些语词的涵意。

利用三角域上V-系统进行三维复杂几何模型的重构实验，实验结果表明，V-系统对复杂的、连续间断并存的几何信息重构特别有效，这与经典的连续正交函数系及强间断的Walsh及Haar函数系有本质的不同。

In this thesis, we will mainly do research on the novel scheme for Digital image Steganography, Digital Image Secret Transmission in network and the development of the information hiding device for application. The main contributions of this thesis are as following: The novel conversion method for mapping image to complex number is proposed, and the plus, minus, multiply and complex conjugate operation of image are defined based on Positional number systems and complex number system. Following new results have been gotten: 1 The suitable complex number basis to be used to express integers is a big set. 2 Any image can be mapping into a one-to-one point. 3 Lots of image processing problem can be considered based on geometric theory.

在本论文中，研究工作集中在数字图像伪装算法的新模型、图像在网络中的加密传输的新方案和信息伪装设备的研发等三个方面，主要包括：基于位值制记数法和复数系理论，提出利用复数作为基底的数字图像新的表示方法，用复数运算定义了图像和图像间的"加"、"减"、"乘"、"共轭"等运算关系；得到理论结果： 1、能表示任何整数的复数基是很大的一个集合。2、任何一幅图像，都能和复平面上的一个点一一对应。3、可以将图像问题化归为平面几何问题处理。4、复数系下的图像表示适合用于信息伪装。
