Abstract

A novel blind watermark algorithm based on DCT is proposed to embed several same watermarks into digital images in this paper. The watermark is designed to be decoded without the original image. Experimental results show that embedded watermarks using the proposed algorithm can give good image quality and are robust in varying degree to JPEG compression, low-pass filtering, noise contamination, and cropping attacks.

一种新的水印盲提取算法

提出了一种基于DCT的盲水印算法，将多个相同的水印嵌入到数字图像中。水印被设计成在没有原始图像的情况下进行解码。实验结果表明，采用该算法嵌入的水印图像质量良好，对JPEG压缩、低通滤波、噪声污染和裁剪攻击具有不同程度的鲁棒性。
