用matlab编程工具，编写具有操作界面的应用程序，通过菜单、对话框，选项框等界面控制，对算法进行演示。需要在应用系统中实现的算法及功能包括：
1、图像增强算法
（1）灰度线形变换：亮度及对比度可以调节（通过控制参数的改变，能够实时预览变化结果）；
（2）直方图均衡：可在界面上对比均衡前后的效果。
2、图像变换算法
（3）对一幅彩色图像进行DCT变换和反变换，对比结果和原图；
（4）仅保留左上角16X16的DCT系数，进行反变换，计算结果图的信噪比SNR。
3、图像分割算法
（5）采用最优阈值算法对灰度图像进行分割；
（6）用Canny算法对灰度图像进行边缘检测；
（7）用hough变换，检测边缘图像中的直线，并用不同颜色将检测出的直线叠加显示到原图像上。

MDFA
实现滑动去趋势波动分析，程序内部有解释，在MDFA文件中可以改变相应的参数值，使结果更好。x中存放的是脑电信号，这里没有上传。可以根据需要，用这种方法处理不同数据。(Achieve sliding detrended fluctuation analysis, is explained within the program, the file can be changed in the MDFA the corresponding parameter values so that the results better. x is stored in the brain signal, there is no upload. As needed, using this method to deal with different data.)
