AT&T Research at TRECVID 2010

AT&T participated in two tasks at TRECVID 2010: contentbased copy detection (CCD) and instance-based search (INS). The CCD system developed for TRECVID 2009 was enhanced for eciency and scale and was augmented by audio features [1]. As a pilot task, participation in INS was meant to evaluate a number of algorithms traditionally used for search in a fully automated setting. In this paper, we report the enhancement of our CCD system and propose a system for INS that attempts to leverage retrieval techniques from dierent audio, video, and textual cues.
