VideoGREP: Video Copy Detection using Inverted File Indices
Arun Hampapur, Rudolf M. Bolle
Technical Report on some unpublished work on index compression for copy detection.
Water marking relies on inserting information into the video stream in order to detect copies. This paper presents a complementary approch to watermarking called content based copy detection(CBCD) which uses a combination of feature based matching and inverted index files to detect copies of video clips. CBCD does not modify the video stream and hence can be applied to find copies of media in circulation. The technique is used to match a test video stream of Super Bowl 2001 containing 10 second clips of Star Wars, against an index of the three Star Wars Special Edition (6 hours) movies.
