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。

Effect of protein and lipid in rice on starch physicochemical characteristics, difference between the region of non-chalkiness and chalkiness of rice, dynamic variation of cell structure and CaM distribution on rice spike were expounded in this study. It was found that protein and lipid in rice had important effect on starch gelatinization, there were distinct differences between the region of non-chalkiness and chalkiness of rice, vascular bundle system in rice spike was changed during grain filling, difference quality of different position of rice spike was more distinct in dense spike rice for more powerful vascular bundle system, the development of rice seeds was corresponded to pericarp development, difference quality of different position of rice spike was also related to transport function of rachilla besides activity of "source", and calmodulin relative activity was closely related to grain filling velocity and enginery properties.

During the study period, we found that plants were present only in natural creek banks, but not altered ones. Comparisons between natural banks without plants and altered banks revealed no significant difference in both shrimp abundance and distribution. However, there was significant difference in shrimp abundance when natural banks with plants and altered banks were compared, suggesting that construction might have negative effects on plants and, in turm, on shrimp abudance. Comparisons between reproductive and non-reproductive season yielded significant results in both shrimp abundance and distribution, which resulted from the recruitment of juveniles to local populations.

在实验期间，自然河段有水蕴草而整治河段没有水蕴草的存在，比较无水蕴草的自然河段与整治河段，发现无论是数量或出现率都没有显著差异，然而，在有水蕴草存在的自然河段之多齿新米虾数量与出现率则较整治河段高，显示哈盆溪可能因为整治工程影响了底质的型态，导致水蕴草不易生长，进而影响多齿新米虾的数量及出现率；在季节方面，结果显示，不同季节在数量和出现率上都有显著差异，而此差异是因为幼虾在生殖季大量加入族群所致。
