提出了一个新的简单而有效的图像数字水印算法。实验结果表明,该算法具有很好的水印透明性,对常见的图像处理攻击(如调整亮度、重采样、颜色抖动、平滑、加噪声和压缩等)具有很好的稳健性。
A novel effective but simple image-watermarking algorithm is proposed. Experimental results show that the algorithm has a fine transparence of embedded watermark and is strongly robust to attacks such as brightness adjusting, re-sampling, color dithering, smoothing, noise adding, and compressing.
