New framework AeroLLE enhances nighttime aerial images with novel calibration

Researchers have introduced AeroLLE, a two-stage framework designed to enhance nighttime aerial images. This method addresses challenges such as uneven lighting and the difficulty of capturing aligned normal-light references from moving platforms. The framework first improves visibility using a base enhancer and then applies Spatially Adaptive Exposure--Color Calibration (SAECC) to refine exposure and color balance. Experiments show that AeroLLE effectively learns from generated appearance guidance, even when registered references are unavailable, by employing constrained, stage-specific calibration. AI

IMPACT This research offers a new approach to image enhancement for challenging nighttime aerial scenes, potentially improving applications in surveillance and mapping.
