大流行情况

But if do not understand this situation, our popular trend of the projected there will be greater deviation.

但是如果不去了解这情况，那么我们的流行态势的推算就会出现更大的偏差。

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。

The single biggest reason, however, was an intensive re-examination of India's epidemic .

然而，最大的一个原因是由于加强了对印度流行情况的复查。

In contrast to the popular assumption that the currently observed globalisation is, to a large extent, due to the decrease of transportation costs, the empirics show a more differentiated picture

相比之下，以流行的假设认为，目前观察在全球经济一体化下，在相当大的程度上，由于减少了运输成本，实证表明，一个更加分化的情况

The so-called " iron rice bowl " prevailed in the past , but things are quite different today .

所谓的&铁饭碗&在过去很流行，但现在的情况有了很大变化。

Agree with above statement, I is the case, single-edged eyelid father, mother double-fold, more than 10 years old when I was changing, but it did not double like her mother, and now my baby for four months, her husband is a double-fold to baby is a single-edged eyelid, it is estimated that like me, I hope that can change it up, but now she is also very good to see single-edged eyelid, double-fold no means all, perhaps, such as popular baby to grow up to become a single-edged eyelid, the giggle laugh, I wish the health of yo

同意楼上说法，我的情况也是这样，爸单眼皮，妈双眼皮，我是十多岁时变的，不过没象妈妈那么双，现在我家宝宝四个月了，老公是大双眼皮，可宝宝是单眼皮，估计是像我了，但愿长大也能变吧，不过现在看她单眼皮也挺好看的，全是双眼皮没什么意思了，也许等宝宝们长大后就流行单眼皮了呢，嘻嘻，祝健康哟

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
