将文件扩展名改成“.m”就可以直接放在工具箱里用了 计算经验模态分解( EMD_ONLINE (On Line Empirical Mode Decomposition) computes on-line EMD IMPORTANT: EMD_ONLINE does not truly apply EMD on-line but it does AS IF. It is rather a demonstration that EMD can be applied on-line.)

图像分割的方法有许多种，其中阈值分割的方法很常用，提供一种基于otsu算法的图像分割方法，很实用。(There are many kinds of method of image segmentation, threshold segmentation method is commonly used, provide a method of image segmentation based on otsu algorithm is very practical)

（1）在MATLAB环境下编写FFT算法（不调用系统现有函数）； （2）实现对选定图片进行FFT计算、还原（IFFT计算），并与系统FFT函数做对比，进行分析； （3）设计GUI界面。((1) the preparation of the FFT algorithm (do not call the system existing function) in MATLAB environment (2) to achieve the selected image to the FFT calculation, reduction (IFFT computing), and FFT functions to do comparison with the system for analysis (3) Design GUI interface.)
