说明：  用于识别图片中有多少个圆。用户只要用windows下的画图随便画若干个圆（不能交叉，但是可以包含）。保存成256色的bmp格式，该程序就能判断出你画的图片上有多少个圆(Used to identify the picture in many circles. Users only need to use the windows painting random drawing under a number of round (can not cross, but it can contain). Save as 256 color bmp format, the program can determine the picture you draw the number of round)

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)

实现提取车牌的车牌边框去除，效果较好，可以一试。(Achieve extraction of the license plate frame license plate removed, is better.)

工具箱，做svm算法时使用的，将其放在toolbox文件夹下，开始matlab运行时调整好路径即可使用(libsvm Toolbox.Used when doing the svm algorithm, put it in the toolbox folder, start the matlab runtime to adjust the path to use)

说明：  pso算法描述，使用pso优化BP神经网络算法，该代码为基于PSO和BP网络的预测(The PSO algorithm is described, and the BP neural network algorithm is optimized by pso. The code is based on the prediction of PSO and BP network.)

这个程序是为了区分SIGNAL和VARIABLE在不同情况下要怎样使用的例程，程序中使用了三种情况来说明问题(This program is designed to differentiate between routine SIGNAL VARIABLE in different situations and how you want to use, the program uses the three cases to illustrate the problem )
