ICA-(PCA)-algorithm

XTHIDE is a GUI that allows the user to hide a text message in an image file. The user will be asked for a key that will be used to both encode and decode the text into an image. The key can be of length from 2 to 900 characters. The encryption pattern for a key hell is not a subset of the encryption pattern for hello . See help. Created with version 7.01.

说明：  基于matlab。利用FFT计算信号的频谱并与信号的真实频谱的抽样比较。 脚本文件T2F.m定义了函数T2F，计算信号的傅立叶变换。(Based on matlab. Calculated using FFT frequency spectrum and the true spectrum of the signal sample comparison. Script file defines a function T2F.m T2F, calculate the Fourier transform of the signal.)
