实现音频中添加数字水印的matlab程序(Add audio digital watermarking matlab program)

说明：  用matlab编写的fft快速傅立叶变换及逆变换函数,其中flip1是供ditfft函数调用的倒叙子函数。(using Matlab fft prepared by the fast Fourier transform and inverse transform function, which is flip1 ditfft function call for the Warrior unreachable.)

此程序为matlab函数，实现用结构相似性（SSIM）准则评价图像，与峰值性噪比的作用类似。(This program is a matlab function, and criteria for evaluation of structural similarity (SSIM) image acts like a peak-noise ratio.)
