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-1 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.
