自编的PSO算法，用于求解函数极值非常不错(Self of the PSO algorithm for solving the extreme value function is very good)

对函数进行采样，经过FFT变换后，画出频谱图，估计出频率。(Sampling of the function, after the FFT transform, the spectrum drawn to estimate the frequency.)

SVM参数优化，网格搜索法，在应用SVM分类时用于优化SVM核函数的c,g参数(Gs SVM)

it s used to detect circles in edge image as input by Hough transform. you can assign a region of interest (ROI) to find center of circle in it.it s effective because time of run is decreased.
