Based on summarizing modern watermarking techniques, the appearance, application, Watermark system principle, classifications and attacks are outlined in this paper. According to the fundamental principles of the information theory, and digital image processing, and chromatology, this thesis studies the theory and applications of the color image watermarking processing.

由于大多数现有技术考虑灰度图像、无意义水印，根据信息隐藏与数字水印技术、数字图像处理和色彩论的基本原理，本文主要研究了彩色图像的有意义水印的处理。

A fundamental problem in the introduction of such digital archiving technology is the lack of widespread ability to review studies electronically (most facilities are equipped only with cine film projectors). In 1995, a joint ACC/NEMA committee established the DICOM 3.0 standard for the transport of digitally archived angiographic studies.

这种数字档案技术主要问题是没有病理资料电子化回放功能(大多数设备配有电影放映机)。1995年，为了传播数字血管造影档案资料的方便，ACC和NEMA共同委员会建立了用于传输的图像资料的有关规则。

As soon as you use a number, that feels all precise, like a code of laws or something, and players only see the number, not the philosophy behind it.

一旦你使用了数字，这让人觉得很精确。就像法典或者其他什么。玩家也只关注数字，而非它背后的哲学。

It's the coercion dot, so named because LabVIEW is coercing one numeric representation to fit another.

它是强制点，如此命名是因为LabVIEW强制一个数字的表示法以匹配另一个数字的表示法。

In order to improve the transmission quality and reliability of the digital communication system, channel coding is proposed.

详细说明：为了改善数字通信系统的传输质量，提高数字通信系统传输的可靠性引入信道编码。

Suzhou Digtal Community Antenna Television came into been on the day of April 28,2001, which is the first one of been virtually operated in our country.

2001年4月28日，苏州有线数字电视正式推出，这也成为我国第一个投入市场运营的数字有线电视。

The pump speeds are controlled through a closed-loop digital system, the same as is used for the cutter and compactor drives.

泵的速度通过一个闭环数字系统得以控制，和切割器及压缩器驱动上使用的闭环数字系统一样。

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。

The most ancient traffical light control unit was designed by digital electric circuit. With the development of science and technology,the traffic light which designed by electric circuit can not contain the increseing pressure of the traffical day by day,so we must find a new method to replace the control unit which is complex and worked insteady.

摘要古老的交通灯控制系统大多是由数字电路来实现的，随着社会经济的发展，数字电路交通灯越来越不能满足日益增长的交通压力，因此必须寻求一种新的方法来取代这种复杂而工作不稳定的控制系统。
