一种基于DCT变换的盲水印检测算法

A DCT-based Watermark Algorithm Without the Original Image

提出了一种基于DCT变换的盲图像水印算法。实验表明 ,该算法对典型攻击具有较好的鲁棒性。

Digital watermarking is a key technique for protecting intellectual property of digital media. A lot of watermarking schemes in DCT domain have been presented. In this paper a new algorithm in DCT domain is discussed. Watermark detecting using this algorithm need not the original image. The experimental results demonstrat that the watermark is robust to general image processing and geometric distortions.
