MDSC: Unsupervised Multipath Decomposition and Synergistic Correction for Efficient Low‐Light Image Enhancement with Detail‐Aware Smoothing

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
This work proposes MDSC, an unsupervised low‐light enhancement framework integrating three core innovations: detail‐aware smoothing, multipath decomposition, and synergistic correction. It suppresses noise, handles rapid illumination variations, and prevents reflectance‐contrast amplification inherent to Retinex separation.

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 ...

A Critical Overview of Common Foodborne Toxicants and Methods for Their Reliable Detection

Food Frontiers, Volume 6, Issue 4, Page 1658-1700, July 2025.
ABSTRACT Food is an essential commodity for human health. However, toxicants such as mycotoxins, heavy metals, acrylamide, and pesticides can be present in food either naturally or through processing, packaging, or some anthropogenic activities. A thorough review of carefully selected studies revealed that climate change and pandemics have led to an ...

Position Calibration and Pixel Correction for Uneven Brightness Micro LED Display

IET Circuits, Devices &Systems, Volume 2025, Issue 1, 2025.
Due to process deviations (Devs) in Micro LEDs, the luminous efficiency of each individual Micro LED can differ. Consequently, this leads to uneven luminance across the Micro LED matrix panel. In this study, a correction algorithm is proposed with the aim of improving luminance inhomogeneity on the panel. The brightness value of each pixel point on the
