DI-Retinex: Digital-Imaging Retinex Theory for Low-Light Image Enhancement
CoRRMany existing methods for low-light image enhancement (LLIE) based on Retinex theory ignore important factors that affect the validity of this theory in digital imaging, such as noise, quantization error, non-linearity, and dynamic range overflow. In this paper, we propose a new expression called Digital-Imaging Retinex theory (DI-Retinex) through ...

Retinex-Diffusion: On Controlling Illumination Conditions in Diffusion Models via Retinex Theory
CoRRThis paper introduces a novel approach to illumination manipulation in diffusion models, addressing the gap in conditional image generation with a focus on lighting conditions. We conceptualize the diffusion model as a black-box image render and strategically decompose its energy function in alignment with the image formation model.
