Algorithm for Video Watermarking Based on Motion Vectors
Zhongjie Zhu · Journal of Circuits and Systems · 2002
Compared with stable pictures, watermarking technology for video must meet blind-detection requirement. In this paper, according to featurelrof motion vector, a new watermarking algorithm for video based on motion vector is proposed. Experimental results show that the proposed algorithm can meet the real-time coding requirement of video images. It is also compatible with present video compressing standards. The embedded watermark by such algorithm can be extracted blindly without affecting the I-frame image quality and degrading PSNR compared with original image .
