摘要
文中将码分多址和扩频水印技术相结合,提出基于码分多址的多重视频水印技术,它既可以灵活地实现水印的多重嵌入与检测同时也具有扩频水印技术的各种优点。
In this paper,a novel CDMA based Multi video watermarking technique is proposed,which results from the combina- tion of CDMA and spread spectrum watermarking technique.The proposed technique not only allows us to embed and extract multi watermark flexibly but also shares the same merits as spread spectrum watermarking.
