中文说明： leeinsar干涉图滤波算法,利用16个窗口选取最佳滤波方向，并利用MMSE估计实现最小均方误差。该滤波器应用广泛，去噪效果好，为进一步的相位解缠提供高质量的干涉图。是目前应用较为广泛的干涉图滤波方法之一。
English Description：
Leeinsar interferogram filtering algorithm uses 16 windows to select the best filtering direction, and uses MMSE estimation to achieve the minimum mean square error. The filter is widely used and has good denoising effect, which provides high quality interferogram for further phase unwrapping. It is one of the widely used interferogram filtering methods.
