毕设时写的程序，主要是人脸识别中的光照处理方法，包括直方图均衡，对数变换，SQI，MQI，SI等。本程序基于opencv实现。-This program demonstrates some illumination normalization methods used in face recognition.Histogram equaliztion,Logarithm transform,SQI,MQI are included.This program is based on opencv.

程序能够完成自商图像的功能，可用于光照条件变化下对于图像的简单处理。加入了单亮区和单暗区，从而减小光照的影响。压缩包中还带有一个迭代阈值选取的小程序。-Program to complete the self-quotient image function can be used to change the lighting conditions under simple treatment for images. Joined the single light and single dark

包含各种图像方面的光照处理程序，有DCT,Gabor,LBP,Retinex,SQI等-ncludes all kinds of image processing procedures, including DCT, Gabor, LBP, Retinex, SQI, etc.
