这是在Matlab中编的图像数字水印的嵌入和提取程序,所用变换为小波变换,并实行盲检测,对搞这方面的研究人员非常有用.(This is made in Matlab in image watermarking embedding and extraction procedures used transform for wavelet transform, and a blind detection, for engaging in research in this area very useful.)

能量检测，根据以URKOWITZ 在1967年发表的能量检测文章以及Digham 2003、Ghasemi 2007发表的一系列文章为参考， 在AWGN信道中，给定SNR下，先产生一个原始信号（单音或者BPSK基带信号），然后叠加高斯噪声， 再进行能量检测(Energy detection, according to URKOWITZ the energy released in the 1967 test articles, and Digham 2003, Ghasemi 2007 series of articles published as a reference, in the AWGN channel, for a given SNR, the first generating an original signal (mono or BPSK baseband signal), and then superimposed Gaussian noise, then the energy detection)

采用BP算法进行函数拟合，收敛速度较快。(BP function fitting algorithm, convergence faster.)

压缩感知的算法，时间比较短，精度比较高。谢谢(Compressed sensing algorithm, the time is short, accuracy is relatively high. Thank you)
