摘要
提出一种新的基于CIRC错误校正的水印信息错误检测和校正算法,该算法根据CRC检测原理对提取出的水印信息进行检测是否错误,如果提取出的水印信息错误则采用CIRC对错误的数据进行纠错。实验结果表明,该算法可以有效地提高水印的鲁棒性。
Through researching on the error check and error correction algorithm,proposes a watermarking algorithm based on CIRC. In this algorithm,the CRC is adopted to check the extracted watermark and CIRC adopted to correct the error extracted watermark.Extensive experiments show that the algorithm possesses significant robustness against the various attacks.
