logistic_dwt
- 】利用混沌动力学系统中logistic 映射先对水印图像进行置乱预处理以增强其鲁棒性, 在小波域中将原始音频信号按比例分段, 此比例为原始音频信号低频部分与水印信号个数之比, 然后将水印信号加入到音频信号的 低频部分。用StirMark 攻击后的实验结果表明, 该算法对StirMark 的部分攻击具有一定的鲁棒性。-The logistic- map sequences to encrypt the watermark are used. The original audio signal

- 小波分析是从傅立叶分析发展出来的一种新的时间频率分析方法,由于它的多尺度分析特征,又被称为时间尺度分析方法。小波变换的基本思想是将原始信号经伸缩及平移后,分解为一系列具有不同空间分辨率、不同频率特性和方向特性的子带信号,这些子带信号具有良好的时域、频域局部特性,这些特征可用来表示原始信号的局部特征,进而实现对信号时间、频率的局部化分析。-DWT-watermark method
