Retinex Poisson Equation: a Model for Color Perception
Image Processing On Line, 2011 In 1964 Edwin H. Land formulated the Retinex theory, the first attempt to simulate and explain how the human visual system perceives color. Unfortunately, the Retinex Land-McCann original algorithm is both complex and not fully specified.

Retinex Based Image Enhancement via General Dictionary Convolutional Sparse Coding
Applied Sciences, 2020 Retinex theory represents the human visual system by showing the relative reflectance of an object under various illumination conditions. A feature of this human visual system is color constancy, and the Retinex theory is designed in consideration of ...

Retinex theory for color image enhancement: A systematic review
International Journal of Electrical and Computer Engineering (IJECE), 2019 <span>A short but comprehensive review of Retinex has been presented in this paper. Retinex theory aims to explain human color perception. In addition, its derivation on modifying the reflectance components has introduced effective approaches for images contrast enhancement.

Low-light image enhancement method based on retinex theory and dual-tree complex wavelet transform
Journal of King Saud University: Computer and Information SciencesImage quality in low-light environments is typically poor, characterized by low contrast, reduced visibility, and sensor noise. These issues not only impair human visual perception but also pose significant challenges for computer vision tasks.

Optimization algorithm for low‐light image enhancement based on Retinex theory
IET Image Processing, 2023 To improve the visual quality of low‐light images and discover hidden details in images, an image enhancement algorithm is proposed, which is based on a fast and robust fuzzy C‐means (FRFCM) clustering algorithm combined with Retinex theory.
