摘要
In this paper, we propose a novel blind MPEG video watermarking technology to hide copyright information by a slight modification of discrete cosine transformation domain in I-frames. It takes full advantage of both stillness and motion information of video content to guarantee the high perceptual invisibility. An effective characteristic extractor of block is delicately designed based on the properties of stillness and motion information, namely the texture, the luminance and the difference between adjacent frames. An eigenfunction is proposed to modify the extracted block characteristic. We illustrated the robustness of the scheme to several video distortions.
