LGScanNet: Gated Local–Global Selective Scanning for Joint Low-Light Enhancement and Deblurring

Mathematics
Images captured in low-light environments often suffer from coupled degradations, including insufficient illumination, amplified noise, and motion blur caused by long exposure: low illumination weakens the structural cues needed for deblurring, while ...
