News reports in TV provide important and timely information about the city and the world to citizens. Moreover, data mining and indexing of news video clips provide a good source of information. However, news video usually consists of more than one news story. One must split them into individual news before indexing. Owing to the nature of news reports, the news anchorperson usually appears in the transition of two news story. Therefore, we propose a new method to find the news anchorperson shot in news video. The MPEG-7 Dominant Color Descriptor (DCD) is adopted to describe video frames. Radial Basis Function Neural Network (RBFNN) trained by minimizing the Localized Generalization Error (L-GEM) is adopted to classify the occurrence of news anchorperson in video frames. Experimental results show that the proposed method is accurate for different news videos from different TV stations.
