一种应用纠错编码的数字水印算法

An Algorithm of Digital Image Watermark Using Error-Correcting Codes

文章提出了一种基于小波变换的结合纠错编码和数据量化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,对常见的图像处理方法显示了较好的健壮性。

In this paper,an algorithm of digital image watermark based on wavelet and data quantification 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 is robust against common image processing operations.
