Chapter 1 gives the background,current research process of relatedproblems and summarizes this thesis\'s work.In chapter 2,we study the Brownian motion with holding and jumping on the boundary.We use the resolvent method to obtain the infinitesimal generator because the domain of the infinitesimal generator is essentially the same as the range of the resolvent.Knowledge of this range and of the differential operator determines uniquely the infinitesimal generator.Since the semigroup generated by the DHJ is not strongly continuous,to use the nice property of strongly continuous semigroup in analytic theory,in chapter 3 we show that the dual is strongly continuous and derive ergodicity through spectral radius formulas and finally obtain the ergodic theorem by duality. In chapter 4,we discuss a class of a more general process---one dimensional Feller diffusion proposed by W.Feller in 1954.The Feller diffusion allows the possibility of jumps from boundary to boundary,not only from boundary to the interior.We give the stationary distribution of this process.

具体地，本文的结构如下：第一章给出了问题产生的背景，研究现状及本文的主要工作；第二章研究了在边界上逗留后随机跳的布朗运动，我(来源：3dABC论文网www.abclunwen.com)们用预解算子的方法得到其无穷小生成元，因为无穷小生成元的定义域本质上就是预解算子的值域，知道这个值域和微分算子形式就能唯一地决定无穷小生成元；由于DHJ过程产生的半群不是强连续的，为利用强连续半群的一些漂亮性质，在第三章中我们证明其对偶半群是强连续的，然后由谱半径公式得到遍历性并且最后由对偶得到遍历定理；第四章讨论了Feller在1954年引入的更广的一类过程----一维Feller扩散过程，Feller扩散过程允许有从边界到边界的跳发生，即不仅仅局限于从边界到内部的跳，在这一章中，我们给出了一维Feller扩散过程的平稳分布；在第五章，我们讨论了一些相关的问题，给出了DHJ过程对应的PDE问题及特征值与收敛速度的关系。

He employs mechanisms more commonly associated with lavish "motion picture" productions for cinema: notably his trompe l'oeil cinematographic vision, manifested in elaborate chiaroscuro combinations of light and half-light; tight control of changes in perspective and arrangement of the cast in majestic tableaux vivants; and a miniaturist's hypersensitivity in committing human emotions to film, his precise handling of the camera capturing the subtleties of sadness, melancholy, and grief as well as of prolonged expressionlessness and impassivity.

他使用了奢华的"电影"更普遍采用的影院制作机制：精心设计出明暗对照的光线组合所产生的电影错视画面；严格控制视角的变化和场面宏伟的活动画面中演员走位的安排；正如一个微图画家般的超敏性，将人类情感赋予电影，通过他对摄影的准确把握，捕捉悲伤、忧郁和哀痛，长时间的沉默和平静的细微差异。

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。

Say filmgoer says kongfu and commerce have what concern above all, I also can raise this question before China, live in China as me and work in Alibaba, and in Chinese deal, the company that I discover the company in the west and east is competing the respect is to have different, if want to see one next case not the motion picture that you want to see an old west only, it is bull-puncher commonly, next of vigorously attack an one fist, of course power is very full inside this, but without what skill but character.

首先说影迷说功夫和商业有什么关系，我在中国之前也会来提这个问题，随着我在中国生活和在阿里巴巴工作，和在中国做生意，我发现在西方的公司和东方的公司在竞争方面是有不同的，假如想看一下一个例子的话不你只要看一个老的西方的电影，一般都是牛仔，然后猛力的击出一拳，当然这里面力量很足，但是没有什么技巧可言。

First of all, the report introduced evolution, achievments and problems in the study of anisotropy in the inner of earth. The first-order hyperbolic system of equations is work out, which is used to describe the wave motion in 2D transversely isotropic media. Utilizing the characteristics of free-divergence, We have imposed MacCormack theme that is used to simulate multicomponent records in anisotropic media and have developed a fast high order vectorized finite-difference algorithm adapted for the vector supercomputer.

In 1965, the Bilderbergers met again. George Adamski takes motion pictures of an object at Silver Spring, Maryland on February 26, 1965. On March 18, the Soviets give a less than adequate performance during the "spacewalk" of Leonov. Its obviously a staged event not taking place in space. In June, astronaut James McDivitt sees an object in space and reports it.

1965年，Bilderbergers再次开会。2月26日﹐乔治亚当斯基乔治亚当斯基在马里兰州银泉拍到了飞碟影片。3月18日，苏联Leonov的"太空漫步"显然不是发生在太空。6月，宇航员詹姆斯麦克迪维特看到太空中的一个物体﹐并且上了报告。
