稀疏表示计算机视觉和模式识别从抽象技术的现象已经可以开始看到稀疏信号在电脑视觉产生重大影响，通常在非传统的应用场合的目标不仅是要获得一个紧凑的高保真度表示的观察信号，而且要提取语义信息。

非常规词典在字典的选择中扮演了重要的角色，衔接的差距或学习、训练样本同来获得自己提供钥匙，解出结果和附加语义意义信号稀疏表示。

理解这种非传统的良好性能要求词典把新的算法和分析技术。

本文强调了一些典型例子：稀疏信号的表现如何互动的和扩展计算机视觉领域，并提出了许多未解的问题为了进一步研究。

稀疏表现已经被证明具有非常强大的工具，获取、表示、压缩高维信号的功能。

它的成功主要是基于这个事实，即重要类型的信号(如声音和图像，稀疏表示很自然地就固定基地或串连这样的基地。

此外，高效、大概有效算法说明基于凸优化一书提供了计算这样的陈述。

虽然这些应用在经典信号处理的铺垫下,已经可以在电脑视觉上形成一个我们经常更感兴趣的内容或语义，而不是一种紧凑、高保真的表示。

一个人可能会理所当然地知道是否可以有用稀疏表示为视觉任务。

答案很大程度上是积极的：在过去的几年里，变化和延伸的最小化已应用于许多视觉任务。

稀疏表示的能力是揭示出语义信息，大部分来自于一个简单但重要的性质数据：虽然照片所展示的图像是在非常高自然的空间，在许多同类应用中图像属于次级结构。

也就是说他们在接近低维子空间或层次。

如果发现一个收集的样本分布，我们理应期望一个典型的样品有一个稀疏表示理论的基础。

然而，想要成功地把稀疏表示应用于电脑视觉，我们通常是必须面对的一个额外的问题，如何正确选择依据。

这里的数据选择不同于在信号处理的传统设置，基于指定的环境具有良好的性能可以被假定。

在电脑视觉方面，我们经常要学习样本图像的任务词典，我们不得不用一个连贯的思想来贯穿工作。

因此，我们需要扩展现有的理论和稀疏表示算法新情况。

自动人像识别仍然是最具有挑战性的应用领域和计算机视觉的难题。

在理论基础实验上，稀疏表示在近期获得了显著的进展。

计算机外⽂翻译（完整）毕业设计(论⽂)外⽂资料翻译专业：计算机科学与技术姓名：王成明学号：06120186外⽂出处：The History of the Internet附件： 1.外⽂原⽂ 2.外⽂资料翻译译⽂；附件1：外⽂原⽂The History of the InternetThe Beginning - ARPAnetThe Internet started as a project by the US government. The object of the project was to create a means of communications between long distance points, in the event of a nation wide emergency or, more specifically, nuclear war. The project was called ARPAnet, and it is what the Internet started as. Funded specifically for military communication, the engineers responsible for ARPANet had no idea of the possibilities of an "Internet."By definition, an 'Internet' is four or more computers connected by a network.ARPAnet achieved its network by using a protocol called TCP/IP. The basics around this protocol was that if information sent over a network failed to get through on one route, it would find another route to work with, as well as establishing a means for one computer to "talk" to another computer, regardless of whether it was a PC or a Macintosh.By the 80's ARPAnet, just years away from becoming the more well known Internet, had 200 computers. The Defense Department, satisfied with ARPAnets results, decided to fully adopt it into service, and connected many military computers and resources into the network. ARPAnet then had 562 computers on its network. By the year 1984, it had over 1000 computers on its network.In 1986 ARPAnet (supposedly) shut down, but only the organization shut down, and the existing networks still existed between the more than 1000 computers. It shut down due to a failied link up with NSF, who wanted to connect its 5 countywide super computers into ARPAnet.With the funding of NSF, new high speed lines were successfully installed at line speeds of 56k (a normal modem nowadays) through telephone lines in 1988. By that time, there were 28,174 computers on the (by then decided) Internet. In 1989 there were 80,000 computers on it. By 1989, there were290,000.Another network was built to support the incredible number of people joining. It was constructed in 1992.Today - The InternetToday, the Internet has become one of the most important technological advancements in the history of humanity. Everyone wants to get 'on line' to experience the wealth of information of the Internet. Millions of people now use the Internet, and it's predicted that by the year 2003 every single person on the planet will have Internet access. The Internet has truly become a way of life in our time and era, and is evolving so quickly its hard to determine where it will go next, as computer and network technology improve every day.HOW IT WORKS:It's a standard thing. People using the Internet. Shopping, playing games,conversing in virtual Internet environments.The Internet is not a 'thing' itself. The Internet cannot just "crash." It functions the same way as the telephone system, only there is no Internet company that runs the Internet.The Internet is a collection of millioins of computers that are all connected to each other, or have the means to connect to each other. The Internet is just like an office network, only it has millions of computers connected to it.The main thing about how the Internet works is communication. How does a computer in Houston know how to access data on a computer in Tokyo to view a webpage?Internet communication, communication among computers connected to the Internet, is based on a language. This language is called TCP/IP. TCP/IP establishes a language for a computer to access and transmit data over the Internet system.But TCP/IP assumes that there is a physical connecetion between onecomputer and another. This is not usually the case. There would have to be a network wire that went to every computer connected to the Internet, but that would make the Internet impossible to access.The physical connection that is requireed is established by way of modems,phonelines, and other modem cable connections (like cable modems or DSL). Modems on computers read and transmit data over established lines,which could be phonelines or data lines. The actual hard core connections are established among computers called routers.A router is a computer that serves as a traffic controller for information.To explain this better, let's look at how a standard computer might viewa webpage.1. The user's computer dials into an Internet Service Provider (ISP). The ISP might in turn be connected to another ISP, or a straight connection into the Internet backbone.2. The user launches a web browser like Netscape or Internet Explorer and types in an internet location to go to.3. Here's where the tricky part comes in. First, the computer sends data about it's data request to a router. A router is a very high speed powerful computer running special software. The collection of routers in the world make what is called a "backbone," on which all the data on the Internet is transferred. The backbone presently operates at a speed of several gigabytes per-second. Such a speed compared to a normal modem is like comparing the heat of the sun to the heat of an ice-cube.Routers handle data that is going back and forth. A router puts small chunks of data into packages called packets, which function similarly to envelopes. So, when the request for the webpage goes through, it uses TCP/IP protocols to tell the router what to do with the data, where it's going, and overall where the user wants to go.4. The router sends these packets to other routers, eventually leadingto the target computer. It's like whisper down the lane (only the information remains intact).5. When the information reaches the target web server, the webserver then begins to send the web page back. A webserver is the computer where the webpage is stored that is running a program that handles requests for the webpage and sends the webpage to whoever wants to see it.6. The webpage is put in packets, sent through routers, and arrive at the users computer where the user can view the webpage once it is assembled.The packets which contain the data also contain special information that lets routers and other computers know how to reassemble the data in the right order.With millions of web pages, and millions of users, using the Internet is not always easy for a beginning user, especially for someone who is not entirely comfortale with using computers. Below you can find tips tricks and help on how to use main services of the Internet.Before you access webpages, you must have a web browser to actually be able to view the webpages. Most Internet Access Providers provide you with a web browser in the software they usually give to customers; you. The fact that you are viewing this page means that you have a web browser. The top two use browsers are Netscape Communicator and Microsoft Internet Explorer. Netscape can be found at /doc/bedc387343323968011c9268.html and MSIE can be found at /doc/bedc387343323968011c9268.html /ie.The fact that you're reading this right now means that you have a web browser.Next you must be familiar with actually using webpages. A webpage is a collection of hyperlinks, images, text, forms, menus, and multimedia. To "navigate" a webpage, simply click the links it provides or follow it's own instructions (like if it has a form you need to use, it will probably instruct you how to use it). Basically, everything about a webpage is made to be self-explanetory. That is the nature of a webpage, to be easily navigatable."Oh no! a 404 error! 'Cannot find web page?'" is a common remark made by new web-users.Sometimes websites have errors. But an error on a website is not the user's fault, of course.A 404 error means that the page you tried to go to does not exist. This could be because the site is still being constructed and the page hasn't been created yet, or because the site author made a typo in the page. There's nothing much to do about a 404 error except for e-mailing the site administrator (of the page you wanted to go to) an telling him/her about the error.A Javascript error is the result of a programming error in the Javascript code of a website. Not all websites utilize Javascript, but many do. Javascript is different from Java, and most browsers now support Javascript. If you are using an old version of a web browser (Netscape 3.0 for example), you might get Javascript errors because sites utilize Javascript versions that your browser does not support. So, you can try getting a newer version of your web browser.E-mail stands for Electronic Mail, and that's what it is. E-mail enables people to send letters, and even files and pictures to each other.To use e-mail, you must have an e-mail client, which is just like a personal post office, since it retrieves and stores e-mail. Secondly, you must have an e-mail account. Most Internet Service Providers provide free e-mail account(s) for free. Some services offer free e-mail, like Hotmail, and Geocities.After configuring your e-mail client with your POP3 and SMTP server address (your e-mail provider will give you that information), you are ready to receive mail.An attachment is a file sent in a letter. If someone sends you an attachment and you don't know who it is, don't run the file, ever. It could be a virus or some other kind of nasty programs. You can't get a virus justby reading e-mail, you'll have to physically execute some form of program for a virus to strike.A signature is a feature of many e-mail programs. A signature is added to the end of every e-mail you send out. You can put a text graphic, your business information, anything you want.Imagine that a computer on the Internet is an island in the sea. The sea is filled with millions of islands. This is the Internet. Imagine an island communicates with other island by sending ships to other islands and receiving ships. The island has ports to accept and send out ships.A computer on the Internet has access nodes called ports. A port is just a symbolic object that allows the computer to operate on a network (or the Internet). This method is similar to the island/ocean symbolism above.Telnet refers to accessing ports on a server directly with a text connection. Almost every kind of Internet function, like accessing web pages,"chatting," and e-mailing is done over a Telnet connection.Telnetting requires a Telnet client. A telnet program comes with the Windows system, so Windows users can access telnet by typing in "telnet" (without the "'s) in the run dialog. Linux has it built into the command line; telnet. A popular telnet program for Macintosh is NCSA telnet.Any server software (web page daemon, chat daemon) can be accessed via telnet, although they are not usually meant to be accessed in such a manner. For instance, it is possible to connect directly to a mail server and check your mail by interfacing with the e-mail server software, but it's easier to use an e-mail client (of course).There are millions of WebPages that come from all over the world, yet how will you know what the address of a page you want is?Search engines save the day. A search engine is a very large website that allows you to search it's own database of websites. For instance, if you wanted to find a website on dogs, you'd search for "dog" or "dogs" or "dog information." Here are a few search-engines.1. Altavista (/doc/bedc387343323968011c9268.html ) - Web spider & Indexed2. Yahoo (/doc/bedc387343323968011c9268.html ) - Web spider & Indexed Collection3. Excite (/doc/bedc387343323968011c9268.html ) - Web spider & Indexed4. Lycos (/doc/bedc387343323968011c9268.html ) - Web spider & Indexed5. Metasearch (/doc/bedc387343323968011c9268.html ) - Multiple searchA web spider is a program used by search engines that goes from page to page, following any link it can possibly find. This means that a search engine can literally map out as much of the Internet as it's own time and speed allows for.An indexed collection uses hand-added links. For instance, on Yahoo's site. You can click on Computers & the Internet. Then you can click on Hardware. Then you can click on Modems, etc., and along the way through sections, there are sites available which relate to what section you're in.Metasearch searches many search engines at the same time, finding the top choices from about 10 search engines, making searching a lot more effective.Once you are able to use search engines, you can effectively find the pages you want.With the arrival of networking and multi user systems, security has always been on the mind of system developers and system operators. Since the dawn of AT&T and its phone network, hackers have been known by many, hackers who find ways all the time of breaking into systems. It used to not be that big of a problem, since networking was limited to big corporate companies or government computers who could afford the necessary computer security.The biggest problem now-a-days is personal information. Why should you be careful while making purchases via a website? Let's look at how the internet works, quickly.The user is transferring credit card information to a webpage. Looks safe, right? Not necessarily. As the user submits the information, it is being streamed through a series of computers that make up the Internet backbone.The information is in little chunks, in packages called packets. Here's the problem: While the information is being transferred through this big backbone, what is preventing a "hacker" from intercepting this data stream at one of the backbone points?Big-brother is not watching you if you access a web site, but users should be aware of potential threats while transmitting private information. There are methods of enforcing security, like password protection, an most importantly, encryption.Encryption means scrambling data into a code that can only be unscrambled on the "other end." Browser's like Netscape Communicator and Internet Explorer feature encryption support for making on-line transfers. Some encryptions work better than others. The most advanced encryption system is called DES (Data Encryption Standard), and it was adopted by the US Defense Department because it was deemed so difficult to 'crack' that they considered it a security risk if it would fall into another countries hands.A DES uses a single key of information to unlock an entire document. The problem is, there are 75 trillion possible keys to use, so it is a highly difficult system to break. One document was cracked and decoded, but it was a combined effort of14,000 computers networked over the Internet that took a while to do it, so most hackers don't have that many resources available.附件2：外⽂资料翻译译⽂Internet的历史起源——ARPAnetInternet是被美国政府作为⼀项⼯程进⾏开发的。

But for Linux, this only numerous news one of. Recently, the manufacturers concerned have announced that support the news of Linux to increase day by day, users' enthusiasm to Linux runs high unprecedentedly too. Then, Linux only have operating system not free more than on earth on 7 year this piece what glamour, get the favors of such numerous important software and hardware manufacturers as the masses of users and Orac le , Informix , HP , Sybase , Corel , Intel , Netscape , Dell ,etc. , OK?1.The background of Linux and characteristicLinux is a kind of " free (Free ) software ": What is called free,mean users can obtain the procedure and source code freely , and can use them freely , including revise or copy etc.. It is a result of cybertimes, numerous technical staff finish its research and development together through Inte rnet, countless user is it test and except fault , can add user expansion function that oneself make conveniently to participate in. As the most outstanding one in free software, Linux has characteristic of the following:(1)Totally follow POSLX standard, expand the network operatingsystem of supporting all AT&T and BSD Unix characteristic. Because of inheritting Unix outstanding design philosophy , and there are clean , stalwart , high-efficient and steady kernels, their all key codes are finished by Li nus Torvalds and other outstanding programmers, without any Unix code of AT&T or Berkeley, so Linu x is not Unix, but Linux and Unix are totally compatible.(2)Real many tasks, multi-user's system, the built-in networksupports, can be with such seamless links as NetWare , Windows NT , OS/2 ,Unix ,etc..

In addition domestic computer Company , person who win of China , devoted to Linux relevant software and hardware application of system popularize too. Is it to intensification that Linux know , will have more and more enterprises accede to the ranks that Linux will be used with domestic every enterprise to believe, more software will be planted in Linux platform. Meanwhile, the domestic university should regard Linux as the original version and upgrade already existing Unix content of courses , start with analysing the source code and revising the kernel and train a large number of senior Linux talents, improve our country's own operating system. Having only really grasped the operating system, the software industry of our country could be got rid of and aped sedulously at present, the passive state led by the nose by others, create conditions for revitalizing the software industry of our country fundamentally.中文翻译Linux—网络时代的操作系统虽然对许多人来说，以Linux作为主要的操作系统组成庞大的工作站群，完成了《泰坦尼克号》的特技制作，已经算是出尽了风头。

Impact on Society
The widespread use of computers has had a profound impact on society, influencing various aspects of our lives. In the workplace, computers have increased productivity, facilitated global collaboration, and created new job opportunities in the technology sector. In education, computers have revolutionized the way students learn and teachers instruct, providing access to vast amounts of information and interactive learning resources.

History of Computers
The history of computers dates back to the 19th century when Charles Babbage invented the first mechanical computer known as the Analytical Engine. However, it was not until the mid-20th century that electronic computers were developed. The first electronic computer, ENIAC, was completed in 1945 and marked the beginning of the digital era. Since then, computers have continued to evolve rapidly, becoming smaller, faster, and more powerful.

计算机英语论文(5篇)计算机英语论文(5篇)计算机英语论文范文第1篇目前移动课件的开发方式有三种：基于HTML5和CSS5的WebAPP开发方式、基于SDK的开发方式和混合开发方式。

1基于HTML5和CSS5的WebAPP开发方式HTML5开发语言简洁，而且兼容性好，现在越来越多的开发者都喜爱使用这种开发语言。

基于HTML5开发的WebApp的核心优势有两点：第一，HTML5技术的优势让开发者以后在做APP应用时不需要写边框、画界线，只需要用一个模板就能够起到界面显示的作用；其次，WebAPP具有卓越的互联互通特性。

但对于高校一线老师来说，存在技术门槛较高，把握起来效率低下等问题。

2基于SDK的开发方式SDK就是SoftwareDevelopmentKit的缩写，中文意思就是“软件开发工具包”。

软件开发工具包广义上指帮助开发某一类软件的相关文档、范例和工具的集合。

使用这种开发方式多为开发方面的专业人员，广阔的高校老师使用起来技术门槛还是比较高，而且开发成本和周期都比较长，不利于教学的准时绽开。

3混合开发方式Rexsee是国内开源的一款移动中间件，它选择深度支持Android平台，并不支持IOS平台。

在Rexsee框架下，用户使用HTML5、CSS3、JavaScript就可以进行移动开发，无需了解Android和Java，服务器端支持使用任何语言，支持在线编译生成APK客户端，无需使用Eclipse等工具，特别适合教学第一线老师开发APP课件使用。

二、课件的开发过程依据以上各方面对比介绍，本文选择使用基于Rexsee框架下的混合开发方式，课件的开发过程如下：下载javaJDK。

到网页中选择“JDK”下载。

在AcceptLicenseAgreement前选择后依据计算机型号选择JDK下载文件，我的是win7操作系统，64位，所以选择jdk-8u25-windows-x64.exeWin7操作系统下安装JDK。

"The Web" is now so popular it has permeated our everyday life, changing how we stay in touch, share information, complete chores, and even earn an income. A whole new industry has sprung up dedicated to providing new ways to improve productivity, in the process changing how we communicate and allowing us to fit ever more into our ever busier lives.Can you use a computer? Can you surf the Internet?I believe that your answer is "yes!'.Now ,most of us can use a computer to surf the Internet . In fact , it's very important for us , we all know that we can do lots of things by surfing the Internet. For example,some students often surf the Internet to find something good for their study , by surfing the Internet,they can learn a lot and make a great progress. When we are free, we often chat with our friends or family members. In the past, if we live very far from our friends or family members we can only write letters to each other, but now Internet can solve this problem ,we can even talk or see each other on computers. Also , we can play games on weekends ,they can help us relax. Of course we can also do many other things on computers. In one word,Internet is really important in our life now.In front of the computer, chatting with others. Apparently, they have lost themselves in the virtual cyber world and become slaves to the Internet. Thus, not to strive, not to seize the opportunities, and not to accomplish anything—these things naturally become the creed of many verdant youths. How so? Internet, just like drug, cigarette, wine, etc. Its mystery depends on its virtual reality. For instance, when you are chatting with others in the net, identity and appearance mean very little in cyberspace, but your thoughts are really matter. And truly, this “faceless” communication does not create problems. At this moment, rather than reveal your weaknesses，you usually show off your strengths as much as possible. Each netizen wants to do the same thing, then admires each other, and finally they even form the love relationship. However, it is hard to know who the other person really is. But usually he or she cannot make out this point and the couple still misses one another. Once they have met, this will inevitably lead to disappointment.The online boyfriend (girlfriend) you imagine is quite different from the real person. Even that person you are looking forward to seeing is an evildoer unexpectedly. And, quite often, it has no real foundation. Furthermore, what we cannot ignore is that surfing the Internet for a long time every day will cost a lot of money, and it is the reason for many delinquencies.If you have become an addict, what should you do? It is not a good idea to suddenly go cold turkey. So, you should wean yourself from it gradually. Firstly, you must understand an important point, that is, life in the real world is far richer than anything you will find on a computer screen. Then you should shorten the time spent on the net little by little. Of course, you need self-control and perseverance. The Internet is a double-edged sword. If you make the best of it, you will benefit a lot. Otherwise, it could do great harm to you.On the whole,with the convenience of the Internet, we should carry on using the Internet. But then ,at the same time, we should distinguish whether the information is worth to believe. Only in this way can the Internet performs its best!“网络”现在是如此受欢迎,它已经渗透到我们的日常生活中,改变我们如何保持联系,分享信息,完成家务,甚至赚取收入。

专业计算机英文作文带翻译英文，As a professional in the field of computer science, I have always been passionate about the ever-evolving technology and its impact on our daily lives. From programming languages to artificial intelligence, the world of computer science is vast and fascinating.I remember when I first started learning about computer programming. It was like learning a new language, with its own syntax and grammar. I struggled at first, but with practice and determination, I was able to write my first program. It was a simple calculator, but the feeling of accomplishment was immense. It was like unlocking a newskill that allowed me to create something out of nothing.As I delved deeper into my studies, I became fascinated by the potential of artificial intelligence. The idea that machines could learn and adapt on their own was mind-boggling. I remember working on a project where I trained a machine learning algorithm to recognize handwritten digits.It was amazing to see the algorithm improve its accuracy over time, almost like it was learning from its mistakes.In my career, I have had the opportunity to work on various projects that have pushed the boundaries of what is possible with computer science. From developing mobile applications to optimizing algorithms for faster processing, each project has presented its own set of challenges and rewards.Computer science is not just about writing code; it's about problem-solving and creativity. It's about finding elegant solutions to complex problems and constantlypushing the boundaries of what technology can achieve. I am excited to see where the field of computer science willtake us in the future.中文，作为计算机科学领域的专业人士，我一直对不断发展的技术及其对我们日常生活的影响充满激情。
