Unifying Path and Center-surround Retinex Algorithms [PDF]

Retinex is a theory of colour vision, and it is also a well known image enhancement algorithm. The Retinex algorithms reported in the literature are often called path-based or centre surround.

RECAD: Retinex-Based Efficient Channel Attention with Dark Area Detection for Underwater Images Enhancement

Journal of Marine Science and Engineering
Focusing on visual target detection for Autonomous Underwater Vehicles (AUVs), this paper investigates enhancement methods for weakly illuminated underwater images, which typically suffer from blurring, color distortion, and non-uniform illumination ...

Entropy–Fidelity Optimization With Deep White‐Balance for Perceptually Consistent Low‐Light Image Enhancement

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.
Low‐light image enhancement is one of the fundamental challenges in computer vision, aiming to improve brightness, contrast, and color balance under insufficient illumination. In this work, we present a novel entropy–fidelity and deep white‐balance (EF–WB) framework that integrates information‐theoretic optimization with deep learning‐based color ...

Illumination compensation for face image using retinex method based on bilateral filtering

, 2010
Illumination variation is one of the critical factors affecting face recognition rate. In the paper, we propose a novel Retinex method based on bilateral filtering to compensate the illumination for face image.

Formalizations of the Retinex model and its variants with variational principles and partial differential equations

, 2017
Edwin H. Land and John J. McCann introduced the Retinex model as a computational theory of color vision. However, Retinex details were described rather algorithmically than mathematically.

Mine image enhancement algorithm based on multi-scale fast bilateral filtering and wavelet transform

Meitan kexue jishu
Due to complex geological conditions and unevenly artificial lighting in underground coal mines, surveillance video images often exhibit non-uniform illumination, detail loss, and low contrast.

A mine image enhancement method based on structural texture decomposition

Gong-kuang zidonghua
There is a phenomenon of low lighting and excessive dust in underground mines, which leads to uneven lighting, blurriness, and loss of details in the images captured by monitoring videos. It affects subsequent intelligent image recognition. Existing mine
