| 摘 要： | 文章提出一种基于DCT域的自适应可见水印算法,该算法根据宿主图像顶部和底部分块的边缘点、纹理和亮度特征对这些块进行分类,将可见水印图像的分块嵌入到最佳嵌入位置;实验结果表明,本算法生成的含水印图像既可保持宿主图像的质量,又能使可见水印细节可见;此外,由于在图像中嵌入了脆弱水印,对其可能受到的攻击可方便地进行检测。

| Abstract: | An adaptive visible watermark algorithm based on the discrete cosine transform(DCT) domain is proposed in this paper.The blocks of the top and bottom of the host image are classified according to the features of edge points,texture and luminance of these blocks.The blocks of the visible watermark image are embedded in the best embedding positions.The experimental results show that the watermarked image generated by this algorithm maintains both the quality of the host image and details of the visible watermark.Meanwhile,any possible attacks on the watermarked image can be detected easily because of the embedded fragile watermark. |
