Variational Retinex Model with Illumination Guidance and Fractional Derivative for Low-Light Enhancement
A variational Retinex model in the image domain is developed for low-light enhancement, which infuses classical/fractional differentiation of the input image into the illumination/reflectance component by means of a structure/texture-aware map (SAM/TAM).
