一个基于纠错码和DCT变换的盲水印算法

A Blind Watermarking Algorithm Based on Error Correcting Code and DCT

提出了一个基于纠错码和DCT变换的图像盲水印算法,该算法利用图像置乱技术和纠错码方法生成水印序列。对不用纠错码、用汉明码和用BCH码的三种水印方案进行了仿真,结果表明利用纠错码的水印方案具有更好的鲁棒性。

A blind image watermarking algorithm based on error correcting code （ECC） and DCT is presented,and the algorithm generates a watermark sequence by using image scrambling technology and ECC method. The three watermarking methods,which are watermark without ECC,with Hamming code and with BCH code,are simulated,and the results show that the method of watermark with ECC has better robustness.
