Figure 2. The proposed low-light image enhancement pipeline. The Decom-Net decomposes the input image into an illumination map and reflectance map, and the Enhance-Net brightens up the illumination map. The reflectance map and illumination map of the low-light image are used as the input of Enhance-Net. The decompositions of normal-light images do not participate in the Enhance-Net training stage.
