AT&T participated in two tasks at TRECVID 2011: contentbased copy detection (CCD) and instance-based search (INS). The CCD system developed for TRECVID 2010 was enhanced for speed and augmented with an additional picturein-picture detector and alternative audio features [1]. As a pilot task, participation in INS evaluated object-level contentbased copy detection and created a basis for integer-score result reranking. This paper reports the enhancements of the CCD system and briefly describe its application to INS for object-level copy detection.
