| 摘 要： | 本文提出了一种基于DCT域的盲水印算法,对水印信息进行Arnold置乱,并结合了载体图像的纹理特征。水印嵌入机制基于载体中两个特定数的相对大小来代表隐藏信息,本文提出的方法有效的改进了两个特定数相互交换后可能对图像产生较大影响。实验表明,该算法具有较好的不可见性,对JPEG压缩、剪切和噪声等攻击方式都具有较好的稳健性。

| Abstract: | In this paper, a kind of blind watermak algorithm based on DCT is proposed. First, the watermak information is scrambled by Arnold scrambling, then make use of the texture features of the carrier image.The watermark embedded method is that two numbers are chosed to hid information with their amount relation. It may makes the image bad results after the two numbers exchanged.And the method proposed in this paper can improve this situation better. Experimental results show that the proposed technique has good... |
