Prior-calibrated spatial-frequency Retinex decomposition for unsupervised low-light image enhancement

SF-GAL, a prior-calibrated spatial-frequency Retinex decomposition framework for unsupervised low-light image enhancement, which calibrates a CLAHE-derived structural prior, decomposes low-light features through complementary spatial and wavelet branches, and uses structure-guided frequency modulation to regulate frequ...
