🔎 Abstract

We introduce ISALux, a novel transformer-based approach for Low-Light Image Enhancement (LLIE) that integrates both illumination and semantic priors.

✨ Key contributions:

• HISA-MSA: A new attention block fusing illumination + semantic segmentation.
• Mixture of Experts (MoE): Improves contextual learning with conditional activation.
• LoRA-enhanced self-attention: Tackles overfitting across diverse light conditions.

Extensive experiments on multiple benchmarks demonstrate state-of-the-art performance.
Ablation studies highlight the role of each proposed component.
