Presently, these roads and bridges can still be found in his paintings, but their construction material has changed to stainless steel, and these segments of polished metal with mirror-like surfaces become abstract elements. They appear as bundles of smooth and shiny linear forms, which seem like actual, physical objects that have been compressed into transcendental bits of soul, and enshroud the dim city which serves as their background.

而今，画面中的桥与路依然存在，改变的是桥的形象被以块面的不锈钢材替代，抛光如镜的金属成为画面中一个抽象的存在，它做为线条造形的集合，平整而光洁，彷佛所有具体的事物都被压成一块无形的魂魄，笼罩在暗黑的城市背景之上。

This is the only method that should be used when erasing unused space or data on a compressed drive.

绝大多数的人们并不知道仅仅删除文件是不够的，因为这样做并没有真正的将数据从计算机上清除干净。

A more implementable measure is the Root Mean Square error between the original image and the image that has been compressed.

更有效的度量方法则是原始图像与压缩图像之间的均方根差。

Adult erythropoiesis is also postulated to recapitulate γ- to β- globin switching, which is called "compressed switch".

在成人骨髓造血干细胞向红系分化发育过程中也存在γ→β基因表达的"压缩性"开关过程。

The shape information of surveillance objects is represented as macro-block coordinates. The temporal redundancy is eliminated by motion estimation within the surveillance region in the reference frame. Since the number of luminance levels is reduced due to enhancement process, the residual error of motion estimation is compressed with lossless entropy coding.

监控对象的形状信息表示为宏块坐标；监控对象之间的时间冗余通过运动估计来消除，但搜索范围限制在前一帧监控对象区域之内；由于增强处理使得监控区域的灰度级减少了，所以对运动估计的残差进行无损熵编码。

When you run an application that hasbeen compressed with PKLITE, the program will automatically be expanded into memory and run.

当使用一个被PKLITE压缩过的应用程序时，程序会自动将自身展开至内存中并开始工作。

Compressed formats are expanded into memory. If the file is quite large, it could take a while to load.

压缩格式文件放进内存，如果这个文件相当大，将会花一些时间在这上面。

However, these applications must be compressed, transmission of large amounts of data,just with simply relying on expanded memory capacity and communication lines to increase the transmission rate would be unrealistic.

但是，这些应用都必须压缩，传输的数据量之大，单纯靠扩大存储器容量、增加通信干线传输速率的办法是不现实的。

Face powder is available either in a loose from or in a compressed form.

面对一个松散的粉末可无论从形式还是在压缩。

It is the first important step in video analysis and will directly affects the effectiveness of indexing Shot boundary detection is one of our major research interests and we will tackle the following existing problems the ambiguity between gradual change and camera motion, the discontinuity during gradual change, false detection caused by illumination variation and flashlight, automatic threshold selection Firstly, we discuss shot boundary detection in non-compressed domain In chapter 2, we compare some of the commonly used detection methods which are based on frame difference and point out that single feature will not generate good results As a conclusion, we use fuzzy logic to combine multiple features Presently, most frame difference based shot boundary detection algorithms rely on threshold and hence the selection of such thresholds will greatly affect the performance of boundary detection We propose a membership function to define frame difference and calculate the membership with self adaptation according to the statistic distribution of frame differences to satisfy different type of video clips Experiments show that the proposed fuzzy shot boundary detection algorithm can be used with different video types and has a high detection precision and recall In chapter 3, we discuss model-based shot boundary detection algorithms regarding chromatic and spatial editing effects such as fade-in, fade-out, dissolve and wipe Various parameters are proposed to better describe the characteristics of each editing type.

镜头边界的检测是把视频自动地分割为一个个镜头，作为基本的索引单元，因此它是视频分析重要的第一步，直接影响到视频检索的成败。镜头边界的检测是本文研究的重点之一。目前镜头边界检测算法主要存在以下问题：渐变与镜头运动难以区别；渐变过程中的不连续与停顿、光照条件的变化及闪光灯等特殊情况会引起误检测；自动选择阈值比较困难等。本文首先针对非压缩域视频进行了镜头边界检测的研究。在第二章中我们采用了比较流行的基于帧间差的方法。在比较各种帧间差计算方法的基础上，指出使用单一的特征难以取得很好的检测效果，提出用模糊逻辑综合使用各种特征。目前大多数基于帧间差的镜头边界检测算法都采用阈值法进行镜头转换的判别。阈值选择的误差对检测性能有较大的影响，本文提出用隶属度函数定义帧间差较大、中等较大和较小等概念，并根据帧间差的统计分布自适应地确定隶属度，以适应不同类型的视频片断。实验结果表明这种基于糊逻辑的镜头边界检测算法可以适应不同的视频，并具有较高的检测精度和检出率。在第三章中采用基于模型的方法进行镜头渐变的检测，研究了淡入／淡出、慢转换和扫换的模型。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。

Talk Undelete failed; someone else may have undeleted the page first.

Talk 无法删除选定的页面或图像（它可能已经被其他人删除了）。
