学生的大部分课余时间都是用来完成教师所布置的曲目，而不是进行独立的思考和选择，所以，在专业技巧得到单方面锻炼的同时，常常忽略了进行积极的自我分析，关注自身特点并依照自身性格特征对演唱曲目进行有效性选择。

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 system schemes are selected in descending probability order. The stopping rule for the state selection is the index accuracy. The relationship between scheme selection accuracy and the forecasting time is also studied. The results show that only a small number of system schemes are required to achieve the high accuracy of the short-term reliability index. Hence, evaluation can be performed in the online environment. The proposed algorithm is applied to the IEEE-RTS.

This paper also applies game theory to set up game models for ante-accommodation and post-accommodation. In the information model for ante-accommodation, commercial banks expect the occurrence of separate game equivalence not the pooled game equivalence, for in pooled game equivalence, commercial banks may easily choose adverse selection to provide loans because of asymmetric information, while in the supervision model for post-accommodation, banks and enterprises hardly make pure strategic equivalence, that is, they can not achieve Pareto optimum in the same time, meanwhile, when the supervision model for post-accommodation achieve pooled strategic equivalence, we will make use of probabilities of enterprises not keeping their promises and probabilities of bank supervision as indexes for describing qualitatively the credit risk for enterprises and the credit risk for bank supervision.
