Mean‐Local Binary Pattern‐Guided Multi‐Attention Network for Low‐Light Image Enhancement
IET Image Processing, Volume 20, Issue 1, January/December 2026.Low‐light image enhancement struggles with noise amplification, residual dark areas, artefacts and detail loss. This paper presents the MGA‐LLIEN network, which uses M‐LBP for adaptive brightness adjustment and detail recovery while reducing noise and outperforms leading methods in tests. ABSTRACT Low‐light image enhancement faces key challenges: noise

LCH‐Net: A Lightweight OKLCH‐Space Decoupling Network for Archival Image Enhancement
IET Image Processing, Volume 20, Issue 1, January/December 2026.This study puts forward the LCH‐Net framework. This method processes lightness, chroma and hue separately in the OKLCH colour space: the lightness adjustment sub‐network adaptively regulates illumination via a learnable lightness curve; the chroma adjustment sub‐network combines frequency‐domain and spatial‐domain denoising to suppress noise while ...

Effective color correction method employing HSV color model
Journal of Measurement Science and Instrumentation, 2012 This paper suggests a new algorithm to solve problems of the current retinex algorithm such as distortion of grey out and color noise due to the individual treatment of RGB channel and log function,and halo effect occurred by use of the Gaussian filter ...

Multi-channel low-light image enhancement method based on global robust Retinex model
Shenzhen Daxue xuebao. Ligong banIn response to the issues where existing illumination enhancement methods ignore the changes in hue and saturation under different lighting conditions, resulting in the loss of excessive detail information while suppressing noise, we propose a global ...
