| 摘 要： | 常规的水印算法在提取水印信息时可能出现误码，文中在采用混沌映射理论提高图像水印加密的安全性基础上，提出了一种基于BCH纠错编码的数字水印算法，通过小波系数的量化法，在小波变换域内实现图像水印的嵌入、提取和水印的恢复。并利用计算仿真进行实验，结果表明，该方法能降低水印提取的误码率，有效抵抗各种常见攻击，具有良好的鲁棒性和不可见性，可靠性和实用性也很强．

| Abstract: | Common watermark arithmetic may cause error code during extraction.Chaotic mapping is proposed to enhance securityof watermark system.Then a digital watermark arithmetic based on BCH coding is introduced,which uses the quantizing algorithms to realize the embeding and extracting of the coded watermarking signals and rebuild them in the wavelet transform domain.The results demonstrate this method can reduce the error bite rate during extraction by some calculations and simulations.These tests prove that the ... |
