While the retinex theory aimed at explaining human color perception, its derivations have led to efficient algorithms enhancing local image contrast, thus permitting among other features, to "see in the shadows". Among these derived algorithms, Multiscale Retinex is probably the most successful center...
M. (2014). Multiscale retinex. Image Processing On Line, 71-88. The first one use an exponential downscaling by 'scalefactor' until 'scalefactor^nscale', this has the advantage of speed up the algorithm for large image but produces more halo artifacts. The second one take as input the ...

This paper proposes an improved Retinex theory based on a weighted guided filter method to enhance images in low-light conditions. The captured images under low illumination can cause dimness, distortion or details loss. We use the weighted guided filter method to perform illumination estimation and...

论文的核心思想类似于Retinex,使用了三个尺度的高斯模糊,再和原图做减法,获得不同程度的细节信息,然后通过一定的组合方式把这些细节信息融合到原图中,从而得到加强原图信息的能力。值得一提的就是对D1的系数做了特殊的处理,算法的编码简单、效果明显。 对应的python实现 # -*- coding: utf-8 -*- import cv2 imp...
