中文说明：Matlab实现界面友好，应用小区域方差对比，程序简单，预报误差法参数辨识-松弛的思想，主要是基于mtlab的程序，表示出两帧图像间各个像素点的相对情况，基于kaiser窗的双谱线插值FFT谐波分析。
English Description：
Matlab realization of friendly interface and application area of regional variance contrast, simple procedures, prediction error method for parameter identification - relaxation of thought, mainly based on MTLAB procedures, showing the relative situations between two adjacent frames of each pixel, based on Kaiser window double spectrum line interpolation FFT algorithm for harmonic analysis.
