Abstract :
Two open problems remain unsolved in the content based video retrieval area. Firstly, how to find useful information and express it by different features. Secondly, how to fuse the heterogeneous information together to boost the retrieval performance beyond any single component. The paper presents two kinds of timing information and their use in concept detection in news video, and a novel non-linear information fusion method to combine timing cues with other information from different sources. Experiments on the TRECVID 2004 dataset show that timing cues can boost performance when combined with other information.
