基于retinex泊松方程的图像颜色校正，retinex方法源于对人类视觉感知系统的建模，因此这类校正方法的结果有比较高的可读性，具有较好的视觉效果，本代码是采用泊松方程来求解这个最优化问题的算法。可以在多个平台上编译运行-Image-based color correction retinex Poisson equation, retinex approach stems from modeling the human visual perception system, so the results of such correction method has a relatively high readability, with better visual effects, the code is the use of mooring Pine equation to solve this optimization algorithms. Can be compiled to run on multiple platforms
