MSIGEN: Multi-Scale Illumination-Guided Low-Light Image Enhancement Network
Abstract
Images lack of light often show the characteristics of low visibility, low contrast and high noise, due to limited imaging equipment. To address the problem, inspired by Retinex theory, we propose a two-stage method called Multi-Scale Illumination-Guided Low-Light Image Enhancement Network (denoted as MSIGEN). In the first stage, we employ an enhancement module to achieve low-light image enhancement, including a Decom-Net for decomposing into illumination and reflectance, an Adjust-Net for illumination adjustment, a Restore-Net for the illumination fusion map guided reflectance restoration. Secondly, the enhancement module is introduced to refine the initial images to effectively remove visual defects amplified and ensure the naturalness of the image. In addition, extensive experiment results demonstrate the advantages of our method and the effect of this method has reached the state-of-the-art.
