SIR

说明：  对图片进行中值滤波，膨胀，腐蚀，二值化处理（matlab）(Median filter on the pictures, expansion, corrosion, binary processing (matlab))

二阶Butterworth滤波器, 可以直接用于数字信号处理，里面有输入输出说明，很详细(Second Order Butterworth Band-Pass Filter)

说明：  感兴趣区域提取。根据人感兴趣的区域对图像进行裁减(Region of interest extraction. According to people interested in the process of reducing the region' s image)

用于黑启动求解频率变化值的PQ潮流分解，输出由每次迭代后各参数的变化量。(PQ trend for black start solving the frequency change value decomposition, the output from each iteration, each parameter change.)
