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。

This dissertation is based on the historical development and the current situation in Pingyao's tourism market, through tourists' poll on the spot and internet, analyzes the overall constitution of the tourists generating market of Pingyao by means of combination of economic and geographic measures through the view of spatial scale and demography, including the total amount of the tourists in Pingyao, the constitution of realistic tourist generating market and potential tourist generating market, the nature of the tourist generating market in Pingyao. The thesis establishes an ACD matrix with the occupation of tourist as a main factor to analyze the relationship between tourist flows and their occupations, with the combination of quantitative and qualitative method to take an insight into the tourist segments selected, in the hope of advising a scientific measure and practicable basis for future development of Pingyao's tourism industry in order to convert the present dilemmatic situation to an optimization.

数据发布平台，依据淡季和春节对平遥旅游者抽样调查问卷资料、网络电子邮件问卷和其他有关历史和现状资料，采用地理分析与市场分析相结合的手段，从空间尺度、人口学特征等方面综合分析了平遥旅游客源市场的总体特征：平遥旅游市场总量状况、现实客源地和潜在客源地构成现状、平遥旅游客源市场的基本特征；对以客源地作为平遥细分市场的分析方法进行了研究，构建出ACD矩阵指导目的地对客源地的选择和细分，进而描述性说明每一类客源地细分市场进入细分选择的依据；将职业特征作为人群细分的标准，通过说明职业特征的高度相关性，以职业细分了平遥的客源市场，定量和定性相结合，分析每一类入选的细分人群，为平遥旅游客源细分市场提供科学的方法，作为平遥下一步开发旅游产品、设计旅游项目的依据，以实现平遥旅游资源的优势转化。

And Tidermann, as mentioned in the earlier part of this synopsis, was one of the editors of Benjamins colleted works in the German version.

在众多的误读者中，我们选择了三个予以集中批驳，他们是汉娜·阿伦特、格哈德·朔勒姆与罗尔夫·蒂德曼，选择的理由是他们都与本雅明有着非常重要的关系，在本雅明研究界有着决定性的影响：阿伦特是著名的哲学家，也是本雅明的《论历史的概念》的受托人；朔勒姆是本雅明的终生挚友，也曾保管过本雅明在《论历史的概念》中写到的极其有名的画作&新天使&；而蒂德曼前己提及是德文版本雅明全集的编辑者之一。

Everything about her had been smooth and definite, even the tones of her voice and the way her light brown hair, which she wore a la Pompadour*, was rolled stiffly back from her forehead and coiled in a burnished rope on the top of her head.

她的一切都是那么安详平淡，那么不事张扬，甚至包括她说话的声调和她选择的发式；她梳的是高卷式发型她梳的是高卷式发型，甚至包括她说话的声调和她选择的发式她梳的是高卷式发型，淡褐色的头发从前额向后紧紧地卷过去用一根光亮的头绳盘绕在头顶上那是一个凡事都严肃认真的年代，的头绳盘绕在头顶上。

Finally, the researchers 51 the children's speech at age 3, using a standardized language test. The only predictors of high scores on the test were the mother's level of education, the 52 of child care and the number of different words the father used. The researchers are 53 why the father's speech, and not the mother's, had an effect."It's well 54 that the mother's language does have an impact," said Nadya Pancsofar, the lead author of the study. It could be that the high-functioning mothers in the study had 55 had a strong influence on their children's speech development, Ms. Pancsofar said, Or it may be that mothers are 56 in a way we didn't measure in the study.

大家可以看一下这十个空五个空是考察动词的，两个空考察名词，两个空考察形容词，还有一个空考察的是副词，可见动词占了一半的比例，而且动词的考察不仅仅考察原形，这里面考察的都是过去时或者是它的ing动名词或者是进行时的一个形式，所以说大家在选择的时候一定要小心，除了根据它具体的单词的含义和上下文的内容来选择之外，还有判断这个单词的形式是不是跟我们这个空按照语法规则是吻合的，所以大家做题一定要小心。
