英文摘要	key project of National Nature Science Foundation of China [61231007]; 863 Hi Tech R&D Program of China [2012AA121604]; International S & T Cooperation Program of China [2012DFG12010]; In recent years, extensive research efforts have been dedicated to automatic news content analysis. In this paper, we propose a novel algorithm for anchorperson detection in news video sequences. In this method, the raw news videos are firstly split into shots by a four-threshold method, and the key frames are extracted from each shot. After that, the anchorperson detection is conducted from these key frames by using a clustering-based method based on a statistical distance of Pearson's correlation coefficient. To evaluate the effectiveness of the proposed method, we have conducted experiments on 10 news sequences. In these experiments, the proposed scheme achieves a recall of 0.96 and a precision of 0.97 for anchorperson detection. (C) 2013 Elsevier B.V. All rights reserved.
