In this paper, we proposed a new low-light image enhancement approach to overcome the above limitations. The proposed algorithm is named as Nature Preserving Lowlight Image Enhancement (NPLIE). NPLIE estimates initial illumination and performs optimal refinement. The proposed algorithm computes the reflectance component through an element-wise division of input image by illumination. The enhanced image is obtained as a product of adjusted illumination and reflectance component. In this work, we estimate initial illuminance from structure-aware smoothening of a low-light image using guided filters of variable box sizes. We compute refined illumination by solving the proposed multi-objective
