News video analysis is an important field of video analysis. In this paper a knowledge based analysis method for news video——a two stage template matching method to detect the anchorperson shot of news video is presented, which is a fundamental step for segmenting news video units. The method is both generic and real time, and can be used in automatic news video analyzing and indexing systems.

新闻视频分析是视频分析领域的重要课题 .提出了一种基于知识的新闻视频分析方法——二阶段模板匹配法 ,用于检测新闻节目中主持人口播镜头 ,从而为新闻单元的定位提供基本依据 .该方法具有通用性和实时性的特点 ,可以在新闻视频的自动分析或自动索引系统中得到实际应用 .

The paper presents an approach, which exploits multimodal information (video, audio and text) to automatically parse news video. In the paper, audio features extraction, as well as multimodal information integration scheme, are addressed in detail. Integration of multiple information sources can overcome the weakness of the approach only exploiting the image analysis techniques. That makes our approach have wider adaptation to variable existence situations of news items. On test data with 184 100 frames, when...

The paper presents an approach, which exploits multimodal information (video, audio and text) to automatically parse news video. In the paper, audio features extraction, as well as multimodal information integration scheme, are addressed in detail. Integration of multiple information sources can overcome the weakness of the approach only exploiting the image analysis techniques. That makes our approach have wider adaptation to variable existence situations of news items. On test data with 184 100 frames, when the system detects boundaries between news items, the recall 95.1% and the accuracy 93.3% are obtained. The experiment results show the approach is valid and robust.

提出一种结合视觉、声音、文字等多种模式信息自动解析新闻视频的方法 ,并对音频特征的提取以及综合多种模式信息解析新闻视频的算法进行了详细的探讨 .多种模式信息的使用有效地弥补了仅基于图像分析技术分割新闻条目的不足 ,从而使该方法对不同方式存在的新闻条目在分割时具有更广泛的适应性 .在包含 184 10 0帧的测试数据集上 ,对于新闻条目边界点的检测 ,系统获得了 95 .1%查全率 ,93.3%的正确率 .实验结果证明了该方法的有效性、强壮性 .

Key frame is the frame which can represent the salient content of the shot.Depending on the content complexity of the shot,one or more key frame can be extracted from a single shot.Key frame extraction has been recognized as one of the important research issues in content-based retrieval.This paper presents some typical approach to extracting key frame from video,and analyzes their difference and shortcomings.Then the paper proposes a algorithm based on text and image information to extract key frame...
