说明：  中位数近似算法实现的背景减除。matlab代码。(Median approximation algorithm for background subtraction. matlab code.)

数值分析国外教材源代码 Atkinson Matlab (Atkinson Matlab )

It is used for input

synchronous machine module using matlab simulink

通过抖动编码，将图像转换成灰度图像；用matlab实现(convert the image to gray level image by using the jitter code method)

这是一个用matlab模拟单缝衍射，光强分布的程序代码(This is a matlab simulation of single slit diffraction, the intensity distribution of the program code)

本人搭建的Matlab风电模型、直驱2MW的，研究塔架振动的(I set up the Matlab, 2 mw direct-drive wind model, the mode of vibration，PMSG)

1、 降噪步骤： （1） 一维信号的小波分解。选择一个小波并确定分解的层次，然后进行分解运算。 （2） 小波分解高频系数的阈值量化。对各个分解尺度下得高频系数选择阈值进行软阈值量化处理。 （3） 一维小波重构。根据小波分解的最底层低频系数和各高频系数进行一维小波重构。 matlab里面有关于去噪的函数，你可以找一下~~ 这说的只是基本原理，希望有所帮助(1, noise reduction steps: (1) one-dimensional signal wavelet decomposition. Select a wavelet decomposition level and determining, and then divide the operation. (2) high coefficient wavelet thresholding. For each decomposition scales have high coefficient selection threshold soft threshold quantization. (3) one-dimensional wavelet reconstruction. According to the lowest level of the low frequency wavelet coefficients and high frequency coefficients of each one-dimensional wavelet reconstruction. There are about denoising matlab function, you can find some ~ ~ This says just the basic principle, we hope to help)
