摘要
文章提供了一种基于小波变换的自适应空间域和变换域相结合的静止图像数字水印算法,水印检测过程不需要利用原始图像信息。实验结果表明,文章提出的数字水印算法对常见的图像处理方法表现出较强的健壮性。
An image watermarking algorithm based on discrete wavelet transform combining transform domain with space domain is proposed in this paper,the original image is not required for detecting the watermark.Experimental results show that the proposed algorithm is robust against common image processing operations.
