摘要: 提出了一种基于四叉树和纠错编码的数字图像水印算法。实验结果表明,该方法简单高效,可嵌入的数字水印信息容量大,而且通过对传统方法的比较,本方法不可见性好,对一般的图像处理和攻击如JPEG压缩、滤波、加噪声、旋转、缩放等有很好的鲁棒性。Abstract: A digital image watermarking algorithm based on quadtree and error correcting code is proposed.Experimental results show that the method is simple,effective,with high capacity of watermark.It has better imperceptibility than traditional methods.And it is robust against normal image processing and kinds of attacks,for example JPEG compression,filtering,adding noise,rotating,zooming.
