摘要

提出了一种在频域中插入伪随机码的小波图像水印方案。水印检测需要原始图像。待嵌入签名的“强度”取决于待标记的图像，从而拟合信号容量。实验结果表明，该方法在频域上比其他已知的私有方法具有更强的抗篡改性和更低的可感知性。

A wavelet-based image watermarking scheme

A wavelet-based image watermarking scheme is proposed, based on the insertion of pseudo-random codes in the frequency domain. The original image is required for the watermark detection. The "strength" of the signature to be embedded depends on the image to be marked, thus fitting signal capacity. The experimental results prove that the method is more tamper resistant and less perceptible for any type of images than other well-known private methods in the frequency domains.
