H.264-Based Video Watermarking Algorithm
Abstract:
Based on the research of image watermarking embedding, we extend our research to deal with the video watermarking. The H.264 standard is used widely and the latest video coding standard at the present. Make good use of the advantages of H.264, such as high compression rate etc., we proposed a low complexity video watermarking algorithm based on H.264. In the proposed algorithm, to weaken the attack of noise, we deal the watermarking image with DWT. And then, we use the Arnold technology to improve the security of watermarking detection. Because of not any modification is done to the data stream of video, only for the division of macro block model, so the quality of video is without of any influence by the algorithm we proposed. By the use of the algorithm, which not only is beneficial to the realization in real time, but also improve the robustness of watermarking, we can easily extract the watermarking image. The experimental results show that the suggested image watermarking algorithm and video watermarking algorithm have good invisibility and strong robustness, and the certain reference value to the actual application.
