Description: Abstract: Effective data processing is required with the fast development of multimedia technology. Compressed-domain images/video processing techniques have captured the attention of many researchers in recent years, and research on face detection and tracking in compressed-domain video becomes a new trend. Based on the analysis of the background and research status, some important future directions are presented.

Description: A general technique for the recovery of signi cant
image features is presented. The technique is based on
the mean shift algorithm, a simple nonparametric pro-
cedure for estimating density gradients. Drawbacks of
the current methods (including robust clustering) are
avoided. Feature space of any nature can be processed,
and as an example, color image segmentation is dis-
cussed. The segmentation is completely autonomous,
only its class is chosen by the user. Thus, the same
program can produce a high quality edge image, or pro-
vide, by extracting all the signi cant colors, a prepro-
cessor for content-based query systems. A 512 512
color image is analyzed in less than 10 seconds on a
standard workstation. Gray level images are handled
as color images having only the lightness coordinate-A general technique for the recovery of sig ni cannot image features is presented.

Description: sed is a stream editor. A stream editor is used to perform basic text transformations on an
input stream (a file or input from a pipeline). While in some ways similar to an editor which
permits scripted edits (such as ed), sed works by making only one pass over the input(s), and is
consequently more efficient. But it is sed’s ability to filter text in a pipeline which particularly
distinguishes it from other types of editors.

Description: Perl借取了C、sed、awk、shell scripting以及很多其他程序语言的特性。其中最重要的特性是它内部集成了正则表达式的功能，以及巨大的第三方代码库CPAN。简而言之，Perl象C一样强大，象awk、sed等脚本描述语言一样方便。-Perl borrows the C, sed, awk, shell scripting, and many other programming language features. One of the most important feature is that it integrates the functionality of regular expressions, as well as a huge third-party code libraries CPAN. In short, Perl is as powerful as C, like awk, sed and other scripting language described as easy.

Description: 本书介绍了一组名字奇特的UNIX实用工具：sed和awk。这组实用工具有很多共同的特征，譬如正则表达式在模式匹配中的应用等。模式匹配在sed和awk的使用中是很重要的部分，因此本书详尽解释了UNIX正则表达式的语法。一般情况下，从grep到sed和awk的学习过程是很自然的，所以本书涵盖了上述3个程序，而重点集中在sed和awk。-This book presents a set of names peculiar UNIX utilities: sed and awk. Utility there are many common characteristics, such as regular expression pattern matching applications. Pattern matching is a very important part in the use of sed and awk, so this book explains in detail the UNIX regular expression syntax. Under normal circumstances, from grep to sed and awk the learning process is very natural, so the book covers these three procedures, focus on sed and awk.

Description: 在计算机科学中，是指一个用来描述或者匹配一系列符合某个句法规则的字符串的单个字符串。在很多文本编辑器或其他工具里，正则表达式通常被用来检索和/或替换那些符合某个模式的文本内容。许多程序设计语言都支持利用正则表达式进行字符串操作。例如，在Perl中就内建了一个功能强大的正则表达式引擎。正则表达式这个概念最初是由Unix中的工具软件（例如sed和grep）普及开的。正则表达式通常缩写成“regex”，单数有regexp、regex，复数有regexps、regexes、regexen。
-In computer science, a single string to be used to describe or match a series string of a syntactic rules. In many text editors or other tools, the regular expression is usually used to retrieve and/or replace the contents of the text that matches a pattern. Many programming languages support the use of regular expressions for string manipulation. For example, the built-in Perl a powerful regular expression engine. Regex the concept was first popularized by the Unix software tools (such as sed and grep). Regular expressions are usually abbreviated as " regex" singular regexp, the regex plural regexps, the regexes by, regexen,.

Description: Linux下sed用法介绍:sed是一个非交互性文本流编辑器。它编辑文件或标准输入导出的文本拷贝。标准输入可能是来自键盘、文件重定向、字符串或变量，或者是一个管道的文本。sed可以做些什么呢？别忘了，Vi也是一个文本编辑器。sed可以随意编辑小或大的文件，有许多sed命令用来编辑、删除，并允许做这项工作时不在现场。sed一次性处理所有改变，因而变得很有效，对用户来讲，最重要的是节省了时间。-Linux, sed usage: sed is a non-interactive text stream editor. Edit a file or standard input export text copy. The standard input from keyboard, file redirection string or variable, or a pipeline of text. sed can do? Do not forget, Vi is a text editor. sed can freely edit the small or large files, many sed command used to edit, delete, and allowed to do this work, not on the scene. sed disposable processing all changes, thus becoming very effective, and the user is concerned, the most important is that it saves time.
