为图片进行添加高斯噪声均匀噪声以及椒盐噪声，并且采用a修正的均值滤波和自适应中值滤波进行除噪，并且进行除噪性能判断-Add a picture for uniform noise and Gaussian noise, salt and pepper noise, and the use of a modified mean filter and adaptive median filtering for noise removal, noise removal performance and

Briefly with the following code I will try to embed the MSB of the baboon image into the picture of Lena by exploiting the LSB embedding technique. We will try also to add an WGN (white gaussian noise) to the image then after these operations we will

利用matlab对图片频域变换、加噪声、计算SNR PSNR，对音频进行处理包括提取高音、低音、并对其进行调制解调-Using matlab frequency domain transform of the picture, add noise to calculate the SNR PSNR of audio processing including the extraction of treble, bass, and its modulation and demodulation
