中文说明：
利用多尺度高斯函数去除场景的光照分量；然后构造了一种二维伽马函数，利用光照分量的分布特性调整二维伽马函数的参数，降低光照过强区域的亮度值，提高光照过暗区域的亮度值，最终实现对光照不均匀图像的自适应校正处理。
English Description：
The multi-scale Gaussian function is used to remove the illumination component of the scene; then a two-dimensional gamma function is constructed, which uses the distribution characteristics of the illumination component to adjust the parameters of the two-dimensional gamma function, so as to reduce the brightness value of the over illuminated area, improve the brightness value of the over illuminated area, and finally realize the adaptive correction of the uneven illumination image.
