logistic_dwt
说明: 】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 in DWT
(Discrete Wavelet Transform) domain is seperated into some pieces determined by the ratio between the length of
the low frequency parts and the length of the encrypted watermark. Every bit of the watermark is added into the
relevant pieces of the low frequency parts in the DWT domain. Experimental results show that the algorithm is
robust against some StirMark attacks.)
