摘要
提出了一种基于离散余弦变换(DCT)域的数字水印算法,该算法从DCT域的中频开始嵌入代表0和1的不相关的高斯随机序列。实验结果证明,该算法具有良好的不可见性,对噪声、滤波、剪切和旋转攻击都有良好的鲁棒性。
This paper proposes a detection watermarking algorithm of images based on discrete cosine transformation, which embeds irrelative Gauss random sequence that represents 0 or 1 into the intermediate frequency of DCT domain. The experimental results prove that this algorithm is invisible, robust against the attack of uniform noise, filter, cut and rotate attack.
