摘要
本文使用计算机领域前沿的Faster-RCNN技术对美国驻华大使馆视频进行目标物视觉识别,并对数据进行统计检验和语义分析,挖掘美国外交视频向中国公众所传递的外交语义及意图。检验发现:检测目标"人"出现频数最高,是主导性关键视像且多以"单个人"形式出现;20类检测目标的出现频数存在显著差异,显示出信息发布意图的特殊性与指向性;引入统计学方法检测"人"出现次数的随机性,证明"人"的分布呈现规律性;将20类检测目标重新归类并统计检验,证明类别"人物"常与生活质量类别的物体关联出现。由此得出美国外交视频的图像语义:聚焦美国普通个体,渲染其民生幸福,以议程设置和框架构建维护美国霸权。
Using an image detection technique known as Faster-RCNN,this paper explores the image semantics conveyed through diplomatic videos by identifying objects on the official videos of the United States Embassy in China. The findings show that the object "person"which has the highest frequency is the dominant visual image,and it is repre sented in most cases in the form of"a single person."In addition,there is significant difference among the 20 categories of objects because of their different frequencies,indicating the uniqueness and directionality of the intentions of those who release the videos. Statistical methods that check the randomness of the "persons' "appearance frequency reveal that there is regular distribution of these "persons"who appear in the videos. What's more,after a re-classification of the 20 categories of objects,it is found that the category of "person"correlates with categories that denote the quality of life. This paper concludes that the image semantics conveyed by U. S. diplomatic videos indicates that the videos intend to promote US hegemony through agenda setting by focusing on average Americans and highlighting their happiness.
