reversible data hiding code for color images

实序列FFT快速算法，用N点FFT计算2N点实序列的FFT，比直接进行2N点FFT运算减少一半运算量。(Real sequence FFT fast algorithm, using N-point FFT calculation 2N point real sequence of FFT, than the direct 2N-point FFT computation halved.)

基于matlab的寿命预测，这是其中几个小程序(life expectance based on matlab)

和声搜索优化算法进行优化，测试方程分为 无限制和限制方程(harmony search algorithm to do the optimization)

该程序实现改进的自适应相关算法，两个matlab文件，一个为函数，该函数求出信号特征量的马氏距离平方并通过梯度下降法训练出其固定阈值，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号特征量的马氏距离平方及其固定阈值求出来，并一起画出图来。 (The program features improved adaptive correlation algorithm, two matlab files, one for the function that calculate the square of the Mahalanobis distance of signal characteristics by gradient descent to train the fixed threshold, the other main function, call The function files the program seek out the square of the Mahalanobis distance and fixed threshold of each channel signal, there are four chanel signal,then draw them out together)
