DSP Implementation of the Retinex Image Enhancement Algorithm

open access: yes, 2004
The Retinex is a general-purpose image enhancement algorithm that is used to produce good visual representations of scenes. It performs a non-linear spatial/spectral transform that synthesizes strong local contrast enhancement and color constancy. A real-

T-Rex: A Milano Retinex Implementation Based on Intensity Thresholding

open access: yes, 2017
We present T-Rex (from the words Threshold and REtineX), a new Milano Retinex implementation, based on an intensity threshold- ing strategy. Like all the algorithms of the Retinex family, T-Rex takes as input a color image and processes its channels ...

A Comparison of the Multiscale Retinex With Other Image Enhancement Techniques

open access: yes, 1997
The multiscale retinex with color restoration (MSRCR) has shown itself to be a very versatile automatic image enhancement algorithm that simultaneously provides dynamic range compression, color constancy, and color rendition. A number of algorithms exist

Gauss-Seidel Retinex

open access: yesJournal of Physics: Conference Series
Abstract Retinex has many algorithmic variants, differing in the method used to decouple illumination from reflectance, including path-based methods, center-surround operators, and lightness processing. The center-surround approach is putatively the most compatible with the human visual mechanism, as it mimics the operation in ...

Adaptive retinex algorithm based on genetic algorithm and human visual system

open access: yes, 2016
Multi-scale retinex is a luminance perceptual algorithm. It is widely used in image enhancement. To get best effect, the parameters need be adjusted according to the scene manually. In order to handle this issue, a novel retinex algorithm based on real-

Algorithm for foggy image enhancement based on the total variational Retinex and gradient domain

open access: yesTongxin xuebao, 2014
Considering the preservation of color constancy and the improvement of contrast ratio of foggy image en-hancement, the foggy image enhancement algorithm based on the total variational Retinex gradient domain method was proposed.
