【摘要】 基于补丁算法提出了一种改进的频域音频数字水印方案．该方案在统计检测理论的基础上,用于音频信号的频域．本方案在嵌入水印信息量的问题上进行了改进,使嵌入信息量有了明显的增加,试验结果表明该方案具有更好的鲁棒性和不可见性,并且重构语音音质较好,隐藏水印能够被很好地被恢复．更多还原

【Abstract】 An improved audio digital watermarking in frequency domain is presented based on the patchwork algorithm. This scheme is based on the statistic detection theory. The experimental results show that the proposed scheme is robust and the amount of watermarking information has been increased greatly.更多还原
