Enhancing Low-Light Color Image via <italic>L</italic><sub>0</sub> Regularization and Reweighted Group Sparsity

Classic Retinex model based low-light image enhancement methods ignored the interference of noise, which causes annoying artifacts. In this paper, we propose to estimate the illumination, reflectance and suppress the noise in a whole framework. Instead of using the <inline-formula> <tex-mat...
