Abstract

Abstract

En
• A three-stage illumination–recursion–chromatic framework is proposed for coal-mine low-light enhancement. • Dual-domain illumination perception integrates YUV luminance and HSV brightness information. • Brightness-adaptive recursive refinement enables spatially selective enhancement of degraded regions. • Coarse-to-fine chromatic normalization restores spectral balance while preserving local details. • Extensive evaluation on coal-mine datasets demonstrate superior visibility and structural recovery.
