VideoAL: a novel end-to-end MPEG-7 video automatic labeling system
In this paper, we describe a novel end-to-end video automatic labeling system, which accepts MPEG-I sequence inputs and generates MPEG-7 XML metadata files based on the prior established anchor models. Seven modules were developed for the system: shot segmentation, region segmentation, annotation, feature extraction, model learning, classification, and XML rendering. The performance of this system has been tested in the NIST TREC-2002 video concept detection benchmark. The proposed system performs best in the mean average precision out of 18 worldwide participants.
