Considering the Nonuniformity of the sensor, an effective method of its correction is presented in this chapter.

本文基于对固体图像传感器的特性及应用方面的要求，着重对其视频输出信号进行了研究。

The image collecting parts mainly complete the conversion of the optics photograph to the image that can be treated by the computer. In this step, the pictures of teeth are shot by CCD and store in the compute at the aid of the video collecting cards. The image processing parts realize the geometric transformation, color adjusting, enhancement, measurement and some specially good effects of the collected images. And at the assist of the image processing, the more image information of dental images is exploited, so that the odontologist can diagnose more accurately.

牙科图像数字化主要完成从光学图像到计算机可处理图像的转换，为系统提供可操作的对象，其基本过程可描述为：通过CCD摄像镜头，对实物进行拍摄，由视频采集卡以信息流的形式对信号实时采集、捕捉，以帧的形式缓存，以静态的图像格式存储在计算机中；牙科图像处理部分不仅实现了图像的几何变换、色彩调整、图像增强以及一些特效，而且对牙齿病变部位进行测量，通过这些操作，能够获得更多的图像信息，提高了医生对病情诊断的科学性；牙科病例数据库部分能够浏览病人的基本信息及牙科图片，实现患者病历的添加、删除、修改等操作，建立患者牙科图像档案的图文数据库。

The whole project is made up of two parts, one is the video capturing system which is based on CMOS video capturing card, the other is single-dot signal capturing system which is based on photoelectric cell.

图像采集单元利用CMOS视频采集设备，采用面向对象的C++编程语言、Visual C++编程工具和微软MFC基础类库设计出信号采集和分析软件。

By means of a new frequency scaling operation, the range migration is corrected without interpolation, and the residual video phase term is removed at the same time.

应用频率变标技术，给出的算法在消除信号剩余视频相位项的同时进行距离单元徙动校正，避免了插值运算。

You can post all sorts of Opportunities, from simple buzz campaigns to product reviews with pictures or videos.

您可以张贴各种机会，从简单的信号运动产品评论的照片或视频。

It also allows video and other complex waveforms to be generated with small details superimposed on large signals.

它还允许视频和其他复杂波形的产生与小细节叠加在大信号。

Recently, of the wireless channel transform operations, especially in the future wireless transform system such as 3G, 4G and wireless LAN with the operation of image and video, because of the wireless channel characteres such as signal fading, multi-way reflection and so on, traditional coding methods become more and more unfitting.

在近来的无线信道传输业务中，特别是在将来的3G、4G以及无线局域网等无线信道传输系统中的图像乃至视频传输业务中，由于无线信道的信号衰落、多径反射等诸多特点，使得传统的编码方法越来越难以胜任。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
