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。

Autumn, and a variety of fruits are beginning to mature, to mature dates, from afar, such as jujube tree on a small fire burning point.

But the rest was on hand, and so they all come and shook hands with the king and thanked him and talked to him; and then they shook hands with the duke and didn't say nothing, but just kept a-smiling and bobbing their heads like a passel of sapheads whilst he made all sorts of signs with his hands and said "Goo-goo -- goo-goo-goo" all the time, like a baby that can't talk.

不过其余的人都在场，他们就一个个走上前来，和国王握手，谢谢他，并和他说起话来。随后他们和公爵握手，并没有说什么话，只是脸上始终透着笑容，频频点点头，活象一群傻瓜蛋。

During the course of using the digital image processing to research and analyze the glass-crack image, apply Microsoft Visual Basic 6.0 grogram language to develop this inspecting system and make the varied arithmetic some individual processing modules. From the open, read and storage of the image to the image segmentation, feature selection until the crack judgment, this system all utilize the modularization program method.

在利用数字图像处理技术研究和分析裂纹图像的过程中，应用了可视化编程语言Visual Basic6.0来开发该检测系统，将各种算法分别做成一个个单独的处理模块，从图像文件的读取、保存到图像预处理在到图像分割、特征提取直至裂纹判断都采用了模块化的编程方法，这样不仅便于算法的编程，还可以使操作界面清晰明了，便于对图像进行处理和操作，提高处理速度。

NET grogram language to develop thisseparating system and makethe varied arithmetic some individual processing moddes.Fromtheopen,read and storage of the image to the image segmentation,feature selection until thejudgment,this system all utilize the modularization program method.

NET来开发和实现了该系统，将各种算法分别做成一个个单独的处理模块，从图像文件的读取、保存到图像预处理再到图像分割、特征提取直至判断识别都采用了模块化编程方法，这样不仅便于算法实现，还可使操作界面清晰明了，更有利于将来系统的维护和升级。

Buffett says it's hard to tell if individual drug companies will do well, but that the group should do well over time."We do not pick one-by-one" when it comes to drug companies.

巴菲特表示如果个别的制药公司都经营地不错，的确很难区别，只能看过去整个表现的如何，当碰到制药类公司时，"我们不去一个个挑选"
