说明：  低照度图像增强，opencv3.2+vs2017，C++代码。 针对全局较暗的图像能有很好的增强效果。 代码注释的很详细，也比较简单。 提供了两张图片以供测试。 若有问题，可以找我。
(Low illumination image enhancement, opencv3.2+vs2017, C++ code. Aiming at the darker image, it can enhance the image very well. The code annotation is very detailed and relatively simple. Two images are provided for testing. If you have any questions, you can come to me.)
