用数字表示的

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。

In digital signal and image processing and digital communications, a continuous signal is usually represented and processed by using its discrete samples.

在数字信号和图像处理以及数字通信中，一个连续信号通常用它的离散采样表示。

If the IEEE double-precision significand has more precision than the internal representation it will be rounded to the internal representation using the round to nearest rule.

如果 IEEE 的双精确有效数字比内部表示法有更多的精确度，它将会被用四舍五入到最接近的规则来四舍五入成内部表示法。

The numbers are part of a grayscale system in which brightness is measured in a range of values.

数字是灰度系统的一部分，在灰度系统中，一个范围内的亮度用一些数字被测量表示。

An octal number system .

有时应用在二进制记数系统中表示数字的一种术语（对比二进制编码的十进制表示或其它用"0"和"1"的表示）。

Not be to state science is metric can use a Chinese character with the one digit that has statistical meaning number, for example: The pagoda tree is disconcerted beach? two kinds of commodity. 4 above (contain 4) number, use 3 phrasing, the span of 1/4 case leaves for nothing between section and section.

不是表示科学计量和有统计意义数字的一位数可以用汉字，例如：一本教材，两种商品等。4位以上(含4位)的数字，采用三位分节法，节和节之间空开1/4格的间距。

Arithmetic can be performed on numbers in any base represented in positional notation.

用位置符号表示任何基底的数字可以完成运算。

If the IEEE single-precision significand has more precision than the internal representation, it will be rounded to the internal representation using the round to nearest rule.

如果 IEEE 的单精确有效数字比内部表示法有更多的精确度，它将会被用四舍五入到最接近的规则来四舍五入成内部表示法。

The numerical cods introduced by Driss Cherqaoui are extended to express molecular structure of individual hydrocarbons in straight rnn gasoline. The molecular structure of individual hydrocarbon is expressed by a fifteen-numer cod.

对Driss Cherqaoui等所采用的数字编码加以扩展后用来表述直馏汽油中的单体烃的分子结构，每一单体烃由一个十五位的数字编码来表示。

A2, in the world, the vast majority of AM points per inch of the number of lines in the dot-matrix, only Germany once in a while the number of dots per centimeter line. 150 line represents the inch 150 x 150 line = 22,500 a number of points, higher numbers, the more business card printing and membership card, the more difficult, making the good paper business card printing and membership card making for behaving as a musician of image quality, the use of more than 300 line number would be closer to the continuous tone of the feeling, on the other hand, are coarse thick wire.

A2、在寰宇上，绝不小众数的AM网不面都以每寸有众少线的不面阵来算，只有德国不常以每公分有众少线筹算。150线表示每寸有150×150线=22，500个网不面，数字越不小不面数越众，制卡和会员卡制作越艰难，在好的纸张制卡和会员卡制作后提下可表示很澈底的影像品格，搁置300线以上的线数不离很挨近不断调的发觉，反之，粗纸不离给用粗网线数。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
