查询词典 ambiguity

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。

双向的断章一方面使赋者所表达的意义更加具体、与情境更加契合，另一方面却也使表达有着多义的可能。而具体语境的限制以及比较一致的心理、文化背景和比喻修辞的使用，又限制了歧义的发生。

Compared with the global harmonic mapping method, this approach has the following advantages.(1) The efficiency of the algorithm is greatly improved. The computational cost involved no longer increases exponentially with the number of vertices of the meshes to be fused.(2) The algorithm is robust as the ambiguity in graph structure combination is alleviated.(3) The detail of the cut mesh is fully kept.(4) The topology restriction of the original algorithm is eliminated.

与原有的基于全局调和映射的融合方法相比，新方法的算法效率大幅度提升，求解时间不再随融合模型顶点数的增加而呈指数增长；减少了二维网格拓扑合并中奇异情况出现的概率，提高了算法的稳定性；被剪切网格的细节得到完整保留；消除了原算法对融合区域拓扑的限制。

Also, ambiguity tends to be dissolved by acceptance tests, because a man in order to know how to test something he must have a very intimate knowledge and understanding of that thing.

同样，通过验收测试，一些不清楚的地方地慢慢地得以消除。这是因为一个人为了测试某种东西他必须有非常丰富的相关知识而且对那样东西非常了解。
