摘要: Content-based copy detection (CBCD) is a complementary approach to watermarking for detecting copies of media. Watermarking relies on the ability detect from distinct pattern that was introduced into original CBCD techniques by measuring distances between content-based signatures extracted and copy. The critical challenge in design signatures, which are invariant differences quality across same media (resolution, compression digitization effects). Most distance measures used image retrieval have been developed without much consideration these types variations copies. This paper examines use several context video compares their performances.
