摘要 抗压缩和水印不可见的数字视频水印技术是当前水印研究中的一个热点,该文提出一种数字视频水印新算法,该算法将水印信息嵌入到视频帧BTBC区域的DCT变换低频系数上,以提高水印的稳健性。实验表明该方案具有良好的抗MPEG-4有损压缩编码的稳健性,并保证了水印的不可见性。 Digital video watermarking technology which can resist compression and watermark invisible is a hot topic in present watermarking researching area. In this paper,a new watermarking algorithm for video images is proposed. This algorithm embeds watermark into low frequency coefficient of DCT in BTBC zone and this scheme can make watermark more robust. According to the experiment results,our scheme is enough robust against the attacks owing to MPEG-4 compression. this scheme also can make watermark invisible.
