利用区域生长法在图像中提取出所需要的部分，本程序为车道线(Using region growing method to extract the required image portion, the procedures for the Drive Line)

DFA方法，检测非平稳时间序列的波动性，用的非常普遍的方法，一种快速计算方法(DFA method)

计算PSNR。可直接调用，两个输入参数im1,im2为两个图象序列，返回值为PSNR的值。(Calculation of PSNR. Can be called directly, two input parameters im1, im2 two image sequences, the return value is the PSNR.)

计算不同曲率半径的透镜焦距，用于光学设计及激光器设计(determine of the focal length of the optical lens, used for optical design or laser design. )

模糊自适应PID 更改模糊规则、隶属函数、系统传递函数即可获得不同系统的模糊自适应PID控制算法(Fuzzy adaptive PID change the fuzzy rules, membership function, the system transfer function can be obtained fuzzy adaptive PID control algorithm of the system)

The zip-file contains the following files for visualizing distributions: - distributionPlot.m: main function that allows creating violin plots - histogram.m: generate histograms with ideal bin width given the number of data points and the spread (Freedman-Diaconis rule). Note that for integer-valued data, each integer gets its own bin. - plotSpread.m: plot point clouds with no overlap. Works well for small number of data points, i.e. when there are less than ~20 values per bin.
