Abstract
The segmentation of news video into story units is an important step towards effective processing and management of large news video archives. In the story segmentation task in TRECVID 2003, a wide variety of techniques were employed by many research groups to segment over 120-hour of news video. The techniques employed range from simple anchor person detector to sophisticated machine learning models based on HMM and Maximum Entropy (ME) approaches. The general results indicate that the judicious use of multi-modality features coupled with rigorous machine learning models could produce effective solutions. This paper presents the algorithms and experience learned in TRECVID evaluations. It also points the way towards the development of scalable technology to process large news video corpuses.
