bw_fragile_robust
matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印,结果肉眼不易分辨出变化,不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过,如修改不严重,可提取隐藏信息,如果修改过多,则只能确定是否有修改,而不知道隐藏的信息是什么(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, such as modification is not serious, can extract hidden information, if too many modifications, you can only determine whether changes were needed, they do not know what information is hidden)

MUSIC
求一个复正弦加白噪声随机过程的信号:
xn=exp(j*pi*n-j*pi)+exp(j*w0*n-j*0.7*pi)+v v(n)为零均值白噪声。S/N=10dB。取P=3,构造4阶的自相关矩阵R的基于MUSIC算法的功率谱估计的MATLAB程序(For a complex sinusoid plus white noise of the signal random process: xn = exp (j* pi* nj* pi)+ exp (j* w0* nj* 0.7* pi)+ v v (n) zero mean white noise. S/N = 10dB. Take P = 3, constructed of 4-order auto-correlation matrix R of the MUSIC algorithm based on power spectrum estimation procedure of MATLAB)
