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.

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...

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.
