Hybrid-Based Compressed Domain Video Fingerprinting Technique
Video fingerprinting is a newer research area. It is also called "Content-based video copy detection" or "Content-based video identification" in literature. The goal is to locate videos with segments substantially identical to segments of a query video while tolerating common artifacts in video processing. Its value as a tool to curb piracy and legally monetize contents becomes more and more apparent in recent years with the wide spread of Internet videos through User Generated Content (UGC) sites like YouTube. Its practical applications to a certain extent overlap with those of digital watermarking, which requires adding artificial information into the contents. Fingerprints are compact content-based signature that summarizes a video signal or another media signal.
