| 摘 要： | 提出了一种新颖的盲检测水印算法.该方法是一种利用图像块的DCT系数的算术均值来隐藏水印信息的盲检测水印算法,该算法在提取水印时不需要原始公开宿主图像,并且对常见水印攻击方法JPEG攻击具有良好的稳健性.

| Abstract: | We bring forward a watermarking algorithm based on mean value of block in DCT domain. By using it, we can hide a smaller image in a bigger image. We can extract the watermarking information from the image that hides watermarking without the original source image. This algorithm can stand against common attacks to some degree. Experimental results show that the algorithm is not only blind but also has good robustness to JPEG attacks. |
