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。

HarryEmerson Fosdick, and they show that people can literally daydreamthemselves to success. Fosdick, aware of the wonderful powerof positive daydreaming, offered this advice: Hold a pictureof yourself long and steadily enough in your mind's eye,and you will be drawn toward it.

引号中的祈使句相当于一个条件状语从句： if youhold a picture …本句意思："福斯迪克知道积极的白日梦的神奇作用，提出了如下的意见："如果你经久地、坚定地在你的想像中给自己描绘一个形象，你将会被引往这个形象。

From the point of view of geobotany, with the method of correlative factors of growth of plants, a countrywide theoretic ecological division was done for the introduction of Camptotheca acuminata and three kinds of areas of ecological preferent zone, ecological adaptive zone and ecological unadaptable zone were divided. With the theory of synecology, the characteristic on environment, constitution, life form spectrum, diversity, similarity of plots of communities were researched. Applying the method of species association, discrete distribution, indensity index, fractal geometry, etc. to research relations between the species of the communities, space distribution of Camptotheca acuminata, structure of age of Camptotheca acuminata, in different communities. Using the theories of autoecology, distibutons of seeds on land and growth of seedlings in vertical and horizontal directions, biomass of organ of Camptotheca acuminata were analyzed. On the opinions of conservation biology, the external and internal factors impressing Camptotheca acuminata were analyzed to research the mechanism of the endangered species, and with using of CTM Model, the future development direction of Camptotheca acuminata in different communities were forecasted, and. Standing on the position of resources ecology, discussing the regularity of camptothein in Camptotheca acuminata of different sites and seeding of different resources, also the the derive technics of camptothecin.

A child hanged to death by a whole night's cold waves Bare, his body has not been Contaminated or filled by dusts Now wholly frozen One night of waiting Is like a century of chaos and loneliness Waiting for the sun to come out And touch him, touch--- Till he slowly and renewedly Turns into water drop by drop Like a candle burned into ashes Inch by inch The stone's aperture Is his end-result Like my hungry and cold childhood Always under mother's eaves Being fed and warmed And now, my heart Like a piece of hailstone Like pieces of hailstone From the hazy sky Falls directly onto the cemented earth 'cause I have no eaves any more

被一夜寒潮吊死的孩子赤裸着尚未被尘埃污染或塞满的身子整个儿已经僵硬那等待中的一夜像混乱而又孤独的一百年就等着太阳出来抚摩他、抚摩——直到他缓缓地一滴滴地重新化成水像蜡烛一寸寸地被烧成灰石头的缝隙是他的归宿像我饥寒的童年总是在母亲的屋檐下被喂养、被温暖而如今，我的心像一颗冰雹像一颗颗冰雹从烟雾弥漫的空中直直地摔到水泥地上因为我已没有屋檐

In this approach, a homography matrix between the ground plane and the image plane is obtained by least square.

它首先利用地平面与图像中的对应点建立一个对应矩阵（homogra-phy），然后利用已知的摄像机高度以及地面上垂线在图像中的投影等约束信息来求取摄像机的参数。

TV broadcasting is an integral part of these creative industries, inextricably-linked with the mass-entertainment film industry, radio, newspapers, magazines, children's toys, electronic games, fashion - with the advertising industry a very prominent "cement" in that structure…They interlock, incestuously perhaps, and provide constant mutual product and programme support.

电视传播是这些创造性产业中的主要部分，它不可避免地与大众娱乐电影产业、广播、报纸、杂志、儿童玩具、电子游戏、时装等联系在一起，而广告业是这个结构中的一种非常重要的黏合剂……它们互相连锁，也许是混乱错杂地交叉渗透，提供持续合作的共同产品和相互支持的节目。

What is/was the general atmosphere in the Chinese WoW community like in the recent weeks, in the infamously rough transition of the game from The9 toNetease?

Basing on this, this article deeply analyzes the relations between implication and the connective "If, then" used in ordinary logical thinking, and points out that material implication is scientific abstract generation to the ordinary language "If, then". Their sameness lies in: when a conditionals protasis is true and its consequent is false, material implication equation is false.

在此基础上，论文深入地分析了蕴涵与人们极易混淆的日常逻辑思维中的"如果，则"的关系，指出实质蕴涵作为数理逻辑中对日常语言"如果，则"的科学抽象地概括，二者的相同点在于：当前件真后件假时，充分条件假言判断为假，实质蕴涵式也为假。
