| 摘 要： | 水印的强度决定其鲁棒性,多数水印算法都是人为地调整水印的嵌入强度,其缺点是只对少数图像适用。针对这一问题,该文提出一种具有自适应性的根据图像本身纹理特性预测出水印强度的算法,适合于多数图像,实验结果证明算法是可行的。

| Abstract: | The robustness of a watermark is determined by the watermark strength. The adjustment of the watermark intensity is made manually now, it is suitable for a few images. In this paper, a method that can automate adjustment of watermark intensity based on the measurement of image texture is proposed, it is suitable for a larger number of images. The results of our experiments show that it is practicable to predict the watermark strength to be applied to an image based on its texture. |
