Watermarking of MPEG2 video streams
نویسنده
چکیده
The main field of this study is digital watermarking of compressed video sequences. The targeted area in the field of digital watermarking is data embedding and indexing, which can be used in applications such as video indexing and retrieval. Having in mind that the content in video databases is mainly compressed and that video retrieval applications

Ensuring security of H.264 videos by using watermarking
Watermarking is known to be a very difficult task. Robustness, Distortion, Payload, Security, Complexity are many constraints to deal with. When applied to a video stream, the difficulty seems to be growing in comparison to image watermarking. Many classical non malicious manipulations of a compressed stream may suppress the embedded information. For example, a simple re-compression of a DVD mo...
متن کاملReal-Time Compressed Video Watermarking in the VLC Domain
This paper proposes a compressed domain video watermarking scheme for copyright protection. In addition to common requirements of watermarking, the unique features of video watermarking such as preservation of bit-rate, compressed domain embedding/detection, and video attacks are examined. For real-time watermark detection, our method is directly applied in the MPEG2 bitstream. More specificall...
متن کاملReal-Time MPEG2 Video Watermarking in the VLC Domain
This paper proposes a compressed domain video watermarking scheme for copyright protection. Our scheme is designed based on the concept of communications with side information. For making the real-time detection a reality, the watermark is directly embedded and detected in the VLC domain. The typical problems of video watermarking such as preservation of bit rate, video attacks, real-time detec...
متن کاملA 2DPCA-Based Video Watermarking Scheme for Resistance to Temporal Desynchronization
Temporal synchronization is a problem that cannot be ignored in most video watermarking application. In this paper, a video watermarking scheme is proposed to resist temporal desynchronization by using shot segmentation and two-dimensional principal component analysis (2DPCA). In this scheme, the to-be-watermarked video is first segmented into different shots. And each shot is analyzed by 2DPCA...
متن کاملRobust multiplicative video watermarking using statistical modeling
The present paper is intended to present a robust multiplicative video watermarking scheme. In this regard, the video signal is segmented into 3-D blocks like cubes, and then, the 3-D wavelet transform is applied to each block. The low frequency components of the wavelet coefficients are then used for data embedding to make the process robust against both malicious and unintentional attacks. Th...
