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 Platform: |

Description: 通过使用matlab自带的小波函数对语音信号进行处理，首先对载入的语音信号snow.wav添加高斯白噪声，然后对加噪的语音信号进行三层小波分解，最后分别采用强制性和默认阈值两种方法对信号进行消噪处理，强制性消噪方法直接将分解的高频系数全部变为0，默认阈值通过对分解的高频系数设定阈值来进行消噪-By using MATLAB built-in wavelet function of speech signal processing, first on the loading of the speech signal snow.wav added white Gaussian noise, and then to the speech signal with noise to three layer wavelet decomposition. At last, the mandatory and the default the signal denoising threshold methods are mandatory elimination noise method directly to the decomposition of the high frequency coefficients all goes to zero, the default threshold by the decomposition of the high frequency coefficients threshold to remove noise Platform: |
