However , the issue how to realize the automatization in ferrograph diagnosis has been brought forth owning to manipulative complexity and subjectivity in the judgement for traditional ferrography technology . thus , the automatic recognition technology for wear debris is a focus research topic and many researchers , whether in overseas or domestic , have paid more attention on studying it last decades 但是，传统铁谱技术操作的复杂性和判断主观性又提出必须尽快解决铁谱诊断智能化的问题，所以磨损磨粒的自动识别技术是近几十年来国内外学者十分关注并致力加以研究的前沿课题。
If we could make use of the technology of computer seeing and realize automatic recognition of identifying id card numbers , we should greatly improve the efficiency of id card administration . presently , most recognition systems of id card numbers are based on scanner , but this systems cannot meet the demand of long and real time catching image . this text lucubrates theoretic about image manipulation and pattern recognition and sets up a integrated regnition system of identifying id card numbers . on ccd vedic . concretery consist : ( 1 ) firstly investigating the segmentation about image of illumination asymmetry . due to a dotal lamp - house , the illumination of id card numbers image is asymmetrical 本文应用了图像处理和模式识别技术，建立了基于摄像头的身份证号码的识别系统。主要研究内容具体包括如下： ( 1 )研究了亮度不均匀的身份证号码图像的分割。由于采用点光源进行局部照射，导致身份证号码图像的亮度不均匀，因此直接对图像采用全局阈值进行分割不能有效地分离号码体。
We know that logistics information automatic recognition technology is the prerequisite that automation system run reliably . it is the new and high technology that incorporates many different disciplines , such as optics , electricity , computer and so on . it is the foundation that gathers and inputs data automatically 我们知道，物流信息自动识别技术是物流自动化系统可靠运行的前提，它是集光、电、计算机等技术为一体的高新技术，是数据自动采集、自动输入的基础，是计算机“实时”处理的重要技术保障，在现代物流系统中发挥着极其重要的作用。
The picture process system of this paper uses digital pattern process technology , has realized the automatic recognition of the machine , so that the degree of accuracy and speed have all been improved greatly . the pictures used in this paper are gathered by ccd system of dynamic testing system of tracking precision of weaponry in real time under the natural light 本文的图像处理系统，采用数字图像处理技术，实现了机器的自动判读，从而准确度和速度都大大提高了。本文实验所用的图像，是由武器装备动态跟踪精度测试系统的ccd系统在自然光下实时采集的，文中的算法由vc语言在windows2000平台下编程实现。
The so - called automatic recognition of modulation ( amr ) schemes automatically classifies the modulation types from the samples of received signal by abstracting the related features such as amplitude , frequency , and phase , followed by employing proper recognition algorithms based on the fast digital signal processing techniques and advanced computing technology . the result of amr can be used in the following processing blocks such as demodulation , supervision processing and anti - interference processing and so on 所谓调制类型自动识别( amr )是根据接收信号样本提取出振幅、频率和相位的特征参数，然后借助信号处理技术和计算机快速处理能力，采用合理算法进行处理，从而实现对未知已调波调制类型的自动识别，为后继的解调、监控、抗干扰等处理奠定基础。
Monitor vehicle or report to the police with automatic recognition for vehicle license plates . so it can be used in many kinds of occasions , such as the charges system of expressway , monitoring system at road and roll - gate , charge and monitoring system at the district , parking area , guide system , the system counting the quantity of vehicle passing in a certain period time , etc . 以自动的车牌号码识别为基础，可以对车辆进行自动登记、验证、监视、报警，进而可以应用在多种场合，如高速公路收费系统：道路、卡口监控系统；小区、停车场收费、监控系统；车流统计、引导系统等。
Secondly , comparing with the algorithm that was given by english scholars a . k . nandi and e . e . azzouz in 1995 , this dissertation presents a modified automatic recognition algorithm of six kind of digital modulation types such as 2ask , 4ask , 2psk , 4psk , 2fsk and 4fsk , which only uses four key features , and has a very great exaltation in the rate of correct recognition and the performance of signal to noise , we puts forward the constitution of the best threshold which is applicable to the signal that changes within the scope of the signal to noise rate ( snr ) from 5db to 30db , and the overall success rate is not lower than 92 % when snr is over 7db 其次,针对1995年英国学者a . k . nandi和e . e . azzouz提出的针对2ask 、 4ask 、 2psk 、 4psk 、 2fsk和4fsk这六种常用的数字调制信号识别的算法,提出了一种数字信号调制方式识别算法( dmra )的改进算法。该算法仅利用四个特征参数,就可以识别这六种调制方式,而且在调制识别率和信噪比性能上都有了很大的提高,能够在信噪比不低于7db时,对实际信号的识别正确率高于92 % 。并且提出了最佳门限的设置方法,设置的门限适用于信噪比在5db ~ 30db范围内变化的信号。
Engineering graphics examination is mostly carried out by written examination and operation on the computer to test the students " grip knowledge , so engineering graphics automatic recognition is one of the exigent problems in the current engineering course examination of the distance education 当前工程图形考试基本上还是采取传统的笔试形式加上机操作进行，来测试学生掌握知识的情况，因此工程图形的自动识别一直是当前远程教育中工科课程考试的一个亟待解决的问题。
This thesis analyses the existing concept - based retrieval systems , based on this introduction , and puts forward a concept retrieval system based on synonyms recognition . automatic recognition of synonyms plays an important role in concept - based information retrieval . based on the analyses of the synonyms recognition , we use the similarity degree among the words to recognize synonyms , and mining a lot of multiple synonyms 同义词的自动发现和识别在基于概念的信息检索领域有着重要的研究意义和应用价值,本文对国内和国外同义词识别算法进行研究和分析的基础上,对基于语义体系的同义词识别算法,即基于《同义词词林》的同义词识别算法和基于《知网》的同义词识别算法进行了深入的研究,利用词汇间的语义相似度度量来进行同义词识别,挖掘出大量的复合词形的同义词。
The vehicle license plate automatic recognition system is one of the important research subjects in the traffic department . because of the variety of the types and conditions in different vehicle license plates , existing system ca n ' t solve all the problems . as the result , this subject is still intractable 汽车牌照自动识别系统是目前交通部门十分重要的的科研项目之一，由于国内的车牌种类较多，汽车所处的环境条件各异，对于鉴控与识别共用一个摄像头的全车身自动识别系统仍是一个急待解决的难题。
