摘要: Digital watermarking is a helpful technology for providing copyright protection valuable multimedia data. In particular, video deals with several issues, which are unique to various types of media watermarking. this paper, these including compressed domain watermarking, real-time detection, bit-rate control, and resistance watermark estimation attacks, will be addressed. Since sequences usually before they transmitted over networks, we first describe how signals can embedded into while keeping the desired nearly unchanged. embedding process, our algorithm designed operate directly in variable length codeword (VLC) satisfy requirement detection. We suitable positions VLC selected transparent watermarks. Second, addition typical peculiar attacks that encounter investigated. order deal both collusion copy fatal frame-dependent (VFDW) presented. Extensive experimental results verify excellent performance proposed system addressing aforementioned issues.
