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 [PDF]
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.

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 Jointed Multiscale CLAHE Model for HDR Image Tone Compression
MathematicsTone-mapping algorithms aim to compress a wide dynamic range image into a narrower dynamic range image suitable for display on imaging devices. A representative tone-mapping algorithm, Retinex theory, reflects color constancy based on the human visual ...

Retinex-qDPC: automatic background rectified quantitative differential phase contrast imaging [PDF]
, 2022 The quality of quantitative differential phase contrast reconstruction (qDPC) can be severely degenerated by the mismatch of the background of two oblique illuminated images, yielding problematic phase recovery results.

Lightness and Retinex Theory [PDF]
Journal of the Optical Society of America, 1971 Sensations of color show a strong correlation with reflectance, even though the amount of visible light reaching the eye depends on the product of reflectance and illumination. The visual system must achieve this remarkable result by a scheme that does not measure flux. Such a scheme is described as the basis of retinex theory. This theory assumes that

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.
