Description: matlab 源码,基于小波变换的语音信息隐藏的实现,对原始语音信息和水印信息都经过三层小波分解处理后,将水印信息的低频信号嵌入原始语音信号的部分高频信号部分实现隐藏.源代码不仅给出隐藏过程,并且给出的在随机噪声,重采样,信息压缩情况下的抗攻击特性.源代码清晰有注释-matlab source code, based on wavelet transform voice messages hidden realize, the original voice information and watermark information after a three-treatment, after wavelet decomposition, the watermark information embedded in the low-frequency signals of the original speech signal realize some hidden part of high-frequency signals. source code is given not only to hide the process, and given in random noise, resampling, compression of information in case of anti-attack features. source code has a clear Notes

Description: 频域法加入数字水印的原理是首先将原始信号（语音一维信号、图像二维信号）变换到频域，常用的变换一般有DWT、DCT、DFT、WP和分形。然后，对加入了水印信息的信号进行频域反变换（IDWT、IDCT、DFT、WP），得到含有水印信息的信号。-Frequency-domain digital watermarking method by adding the principle is that first of all, the original signal (voice signal of one-dimensional, two-dimensional image signal) to frequency domain transformation, commonly used in general transform DWT, DCT, DFT, WP and fractal. Then, adding the watermark information signal to the frequency domain inverse transform (IDWT, IDCT, DFT, WP), received signal containing the watermark information.
