| Abstract: |
| 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. |
