高频系数融合均采用基于像素点绝对值取大的规则,这里要注意的是,比较的对象是两幅原始图像的像素点的绝对值,而融合后图像的像素点的取值是两幅原始图像像素点绝对值大的那一点的值,也就是说,要取绝对值大的那个点的实际值

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.)

仿真程序:首先需要用一个随机发生器产生(0.1)内的均匀随机数,然后再将该序列映射到对应的幅度电平{Am}。然后将这个范围再分成4个相等的区间,这些子区间分别对应于4个信号比特的符号00,01,10,11。检测器观察到r=Am+n,并且计算r和4种可能传输的信号幅度之间的距离,它的输出Bm就是相应于最小距离的信号电平。Bm与真正的的传输信号幅度比较,差错计数器用来对检测器产生的差错计数。(Simulation program: first need to use a random generator (0.1) the uniform random number, then the sequence is mapped to the corresponding amplitude level {Am}. Then this range has been divided into four equal intervals, these sub-intervals corresponding to four signal bits of the symbol 00,01,10,11. Detector observed r = Am+ n, and calculate r and 4 possible transmission distance between the signal amplitude, its output corresponding to the minimum distance Bm is the signal level. Bm and the real rate of transmission of the signal comparison, error detection counter is used to generate the error count.)
