Image Processing On Line, 2014 While the retinex theory aimed at explaining human color perception, its derivations have led to efficient algorithms enhancing local image contrast, thus permitting among other features, to "see in the shadows".

Color and Imaging Conference, 2019 Retinex is a colour vision model introduced by Land more than 40 years ago. Since then, it has also been widely and successfully used for image enhancement. However, Retinex often introduces colour and halo artefacts. Artefacts are a necessary consequence of the per channel color processing and the lack of any strong control for controlling the ...

Designator Retinex, Milano Retinex and the locality issue
Electronic Imaging, 2016 Several different implementations of the Retinex model have derived from the original Land and McCann paper. This paper aims at presenting two of them: the Land Designator and Milano Retinex. Land Designator is an alternative calculation described in his

Journal of Electronic Imaging, 2017 Several different implementations of the Retinex model have been derived from the original Land and McCann’s paper. This paper aims at presenting the Milano-Retinex family, a collection of slightly different Retinex implementations, developed by the Department of Computer Science of Universita degli Studi di Milano. One important difference is in their

2022 16th International Conference on Signal-Image Technology & Internet-Based Systems (SITIS), 2022 The Retinex algorithms find wide applications as image enhancers, for their capability of preserving edges, while at the same time attenuating smooth gradients and chromatic dominants. They are characterized by the fact that the output chromatic intensity of a pixel is not determined in isolation (or looking only at the contiguous pixels) but through ...

Multiscale Retinex Application to Analyze Face Recognition [PDF]
JOIN: Jurnal Online Informatika, 2020 The main challenge that facial recognition introduces is the difficulty of uneven lighting or dark tendencies. The image is poorly lit, which makes it difficult for the system to perform facial recognition.

QBRIX: a quantile-based approach to retinex [PDF]
Journal of the Optical Society of America A, 2014 In this paper, we introduce a novel probabilistic version of retinex. It is based on a probabilistic formalization of the random spray retinex sampling and contributes to the investigation of the spatial properties of the model. Various versions available of the retinex algorithm are characterized by different procedures for exploring the image content

Journal of Electronic Imaging, 2017 Retinex theory estimates the human color sensation at any observed point by correcting its color based on the spatial arrangement of the colors in proximate regions. In this work, we revise two recent path-based, edge-aware Retinex implementations: Termite Retinex (TR) and Energy-driven Termite Retinex (ETR).
