将原信号进行EMD分解，得到一系列IMF分量，这些分量是按频率从高到低排列(EMD decomposition of the original signal to obtain a series of IMF components, which are arranged according to the frequency high to low)

空域滤波器一种--MVDR波束形成器，以《现代信号处理》（张贤达）书上所讲过程所写(Spatial filter one kind- MVDR beamformer to the "Modern Signal Processing" (Zhang XD) wrote the book talking about the process)

在一维信号中，用来抑制噪声干扰并保留有用信号，或者对有用信号进行各种变换的数字滤波器有着广泛的应用，在2维中同样的重要，这里面的源代码就是MATLAB经典的线性滤波技术(In one-dimensional signals, used to suppress noise and retain the useful signal, or a variety of useful signal transform digital filter has a wide range of applications, in the 2-dimensional equally important, which is inside the source code of MATLAB classic Linear Filtering Technology)

This method usually increases the global contrast of many images, especially when the usable data of the image is represented by close contrast values. Through this adjustment, the intensities can be better distributed on the histogram. This allows for areas of lower local contrast to gain a higher contrast. Histogram equalization accomplishes this by effectively spreading out the most frequent intensity values.

二维正态分布的检验函数，如果需要进行二维正态分布的检验，在你的程序运行前运行此程序，就可直接调用函数功能。(Dimensional normal distribution test function, if you need a two-dimensional normal distribution test, run your program before you run this program, you can directly call the function function.)
