Control parameters for Retinex

open access: yes, 2001
The recently published Matlab implementation of the retinex algorithm 2 has free parameters for the user to specify. The parameters include the number of iterations to perform at each spatial scale, the viewing angle, image resolution, and the lookup ...

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.

Multi-Scale Retinex For Color Image Enhancement

open access: yes, 1996
The retinex is a human perception-based image processing algorithm which provides color constancy and dynamic range compression. We have previously reported on a singlescale retinex (SSR) and shown that it can either achieve color/lightness rendition or ...

DSP Implementation of the Multiscale 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.
