At & T Research at Trecvid 2006

TRECVID (TREC Video Retrieval Evaluation) is sponsored by NIST to encourage research in digital video indexing and retrieval. It was initiated in 2001 as a “video track” of TREC and became an independent evaluation in 2003. AT&T participated in three tasks in TRECVID 2006: shot boundary determination (SBD), search, and rushes exploitation. The proposed SBD algorithm contains a set of finite state machine (FSM) based detectors for pure cut, fast dissolve, fade in, fade out, dissolve, and wipe. Support vector machine (SVM) is applied to cut and dissolve detectors to further boost the SBD performance. AT&T collaborated with Columbia University in the search and rushes exploitation tasks. In this paper, we mainly focus on the SBD system and briefly introduce our effort on the search and the rushes exploitation. The AT&T SBD system is highly effective and its evaluation results are among the best.
