Core Innovation

This paper introduces a novel lightweight UIE framework integrating frequency priors via Multi-Branch Reparameterizable Convolution with Fixed DCT Priors and a Frequency-Guided Dual-Path Attention module. Unlike prior spatial-only methods, it fuses spatial and spectral features for adaptive enhancement with negligible inference overhead, achieving superior performance with minimal parameters.

Why It Matters
