摘要
文章提出了一种基于小波变换和纠错编码的数字图像水印算法,该算法不需要利用原始图像。实验结果表明,该算法较好地保持了图像的质量,并大大提高了检测的可靠性,对常见的图像处理方法显示了较强的鲁棒性。
In this paper,an algorithm of digital image watermark based on wavelet and error -correcting codes is introduced,and the original image is not required for detecting the watermark.Experimental results show that the proposed algorithm keeps the quality of the image well and improves the dependability of detecting the watermark and is robust against common image processing operations.
