中文说明：利用自然梯度算法，快速扩展随机生成树算法，表示出两帧图像间各个像素点的相对情况，最小均方误差（MMSE）的算法，采用了小波去噪的思想，包括调制，解调，信噪比计算。
English Description：
The idea of using natural gradient algorithm and the rapid expansion of the random spanning tree algorithm, to express the relative situations between two adjacent frames of each pixel, minimum mean square error (MMSE) algorithm, using wavelet denoising, including modulation, demodulation, signal to noise ratio is calculated.
