PCA人脸识别算法，识别率达到99 ，采用小波变换的方法及主成分分析法。(PCA face recognition algorithm, the recognition rate up to 99 , using wavelet transform methods and principal component analysis.)

数值积分方法计算积分方程，利用复化辛普森公式离散积分项(Integral equation numerical integration method, the use of complex discrete integral term of Simpson formula)

We propose a novel fluorescence emission difference microscopy (FED) system based on focusing cy- lindrical vector beams. In conventional FED, a Gaussian beam and a 0–2 π vortex phase plate are used to generate solid and hollow spots. We focus radially polarized and azimuthally polarized cylindrical vector beams to obtain an expanded solid spot and a shrunken hollow spot, taking advantage of the optical properties of cylindrical vector beams to improve the conventional FED performance. Our novel method enhances FED performance

code can used for determining correlation value to analyze rho based on s11, s12, s21, s22.

Manages the interaction between the secure system setting for default geolocation.
