在数字上

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。

文中首先在内在几何学的层次上，研究了服装设计所涉及的几何学问题，应用标架与半测地坐标方法证明了曲面成为可展面的基本定理，研究了可展面的分类及其性质，考虑到服装三维几何造型的需要，证明了组合式可展面各组成片相切连接条件的命题，作为构造可展面的理论依据，证明了单参数平面族的包络面必为可展面的命题，在此基础上发展出服装几何造型的"刮大白"方法以及相关的三种构造可展面的解析方法。3D→2D的变换是三维服装CAD的重要内容之一，其几何学实质是曲面的定长映射，文中总结了定长映射即可展面在平面上展开的基本准则，在这一准则的指导下，结合服装设计与相关领域的要求，讨论了可展面在平面上展开的解析方法与数字方法，上述内容确立了服装设计几何学的基本框架。

He made codes like Justinian, he dictated like Caesar, his conversation was mingled with the lightning-flash of Pascal, with the thunderclap of Tacitus, he made history and he wrote it, his bulletins are Iliads, he combined the cipher of Newton with the metaphor of Mahomet, he left behind him in the East words as great as the pyramids, at Tilsit he taught Emperors majesty, at the Academy of Sciences he replied to Laplace, in the Council of State be held his own against Merlin, he gave a soul to the geometry of the first, and to the chicanery of the last, he was a legist with the attorneys and sidereal with the astronomers; like Cromwell blowing out one of two candles, he went to the Temple to bargain for a curtain tassel; he saw everything; he knew everything; which did not prevent him from laughing good-naturedly beside the cradle of his little child; and all at once, frightened Europe lent an ear, armies put themselves in motion, parks of artillery rumbled, pontoons stretched over the rivers, clouds of cavalry galloped in the storm, cries, trumpets, a trembling of thrones in every direction, the frontiers of kingdoms oscillated on the map, the sound of a superhuman sword was heard, as it was drawn from its sheath; they beheld him, him, rise erect on the horizon with a blazing brand in his hand, and a glow in his eyes, unfolding amid the thunder, his two wings, the grand army and the old guard, and he was the archangel of war!

他象查士丁尼那样制定法典，象恺撒那样独理万机，他的谈吐兼有帕斯加尔的闪电和塔西佗的雷霆，他创造历史，也写历史，他的战报是诗篇，他把牛顿的数字和穆罕默德的妙喻糅合在一起，他在东方留下了象金字塔那样高大的训谕；他在提尔西特把朝仪教给各国帝王，他在科学院里和拉普拉斯争鸣，他在国务会议上和梅尔兰辩论，他经心整饬纪律，悉力排难解纷，他象检察官一样了解法律，象天文学家一样了解天文；象克伦威尔吹灭两支蜡烛中的一支那样，他也到大庙①去为一粒窗帘珠子讨价还价；他见到一切，他知道一切，这并不妨碍他伏在他小儿子的摇篮上笑得象个天真烂漫的人；突然，惊骇中的欧洲屏息细听，大军源源开拔了，炮队纷纷滚动了，长江大河上建起了浮桥，狂风中驰聘着漫山遍野的骑兵，叫喊声，号角声，所有的宝座全震动了，所有的王国的国境线全在地图上摇晃起来了，人们听到一把超人的宝剑的出鞘声，人们看见他屹立在天边，手里烈焰飞腾，眼里光芒四射，霹雳一声，展开了他的两翼，大军和老羽林军，威猛天神也不过如此！

Its measurement is the measurement of time, the status of the translucent screen Department or looking at the version will mesh ruler in wire mesh network, and then set the gauge wire edge network, so that the vertical line on the screen ruler and MEST warp or weft parallel, at which point due to the mesh screen coordinates and produces overlapping on vertical ruler that formed over the mesh inferion-edged chevrons patterns within the meaning of the transverse diagonal mesh feet on the scale of numbers, that is, the measured screen mesh size.

其丈量办法是：丈量时，首先使丝网处在透亮的状况下或不收在看版台下，不兵网纲尺不收在丝网上，然后不兵网纲尺在丝网上匆匆安放，使网纲尺上的竖线与丝网的不经线或经线交错，这时由于丝网经经线和网纲尺上竖线爆发重叠成果，在网纲尺上变成棱形斑纹，斑纹的横向对角所指的网纲尺上对应的刻度数字，即是所测丝网的纲数。
