摘要 文章提出了一种用于盲水印检测的方法和自适应水印加入算法。在该算法中被加入水印的能量可以根据图像能量的变化而变化,而在检测水印是否存在时只需要计算水印与待检测图像之间的相关系数就可以得出图像中是否含有水印。 A blind watermark detection and adaptive watermark embedding method is supposed in this paper.In this method,the energy of watermark is varied by the energy of image.Watermark could be detected by calculating the correlative coefficient between watermark and image.
