如果想要在一段新聞出分辨出是主撥撥報新聞的片段或是新聞片段,可以經由搜尋主撥的人臉這個動作來分辨出現在這個片段是主撥撥報新聞的片段或是新聞片段,因為現有的人臉辨識方法都需要大量複雜的數學運算才能有效的辨識出人臉,如果想要完成Real-Time 的處理,硬體需求可能會很高。

In this thesis, we designed a scheme for TV news segmentation via video content analysis techniques and explored the efficient visual features. The scheme can be divided into three parts, such as anchorperson shot change detection based on skin color, probable anchorperson segment detection and anchorperson detection.
An anchorperson shot surely contains face region, and this feature is informative and important for anchorperson shot change detection. In order to reduce computational complexity for face detection, we only use skin color information as the major tool for searching face region. Otherwise, the anchorperson shot time should be shorter than that of a report shot time. As a result, we make use of the properties above also called time constraint method to discover the probable anchorperson segments. However, the probable anchorperson segment might involve the report segment, it will effect the detect precision. Here, we exploit the region histogram based on non-skin color method to exclude report segments.
According to simulation results, our proposed method can efficiently decompose TV news into anchorperson shots and report segments. The proposed method can easily apply to software and hardware based personal video recorder for efficiently accessing the large amount of TV news video in the near future.
