一个PSO算法历程，有详细的注释，及相关演示过程。采用了基本PSO、权重优化、最大速度法三种（去掉代码中的相关行的注释即可使用）。(PSO algorithm is a process, detailed notes, and related presentation process. With the basic PSO, weight optimization, the maximum speed law of three (remove the code related to the comment line can be used).)

经验模态分解，EMD代码，采用经验模态分解求取行波故障波形突变点(emd code)

1.对原图像高斯平滑 　　2.对高斯平滑后的图像进行sobel边缘检测。这里需要求横的和竖的还有联合的，所以一共三个需要sobel边缘检测图像。 　　3.对联合的sobel检测图像进行非极大抑制 　　4.连接边缘点并进行滞后阈值处理。 (1. Gaussian smoothing the original image 2. Gaussian smoothed image was sobel edge detection. Here and there on request transverse vertical joint, so a total of three required sobel edge detection image. 3. sobel joint detection image greatly inhibit non- 4. Connect the edge point and hysteresis thresholding.)
