New RISE framework enhances low-light images using structural illumination

Researchers have developed a new framework called Relative Illumination Structure Estimation (RISE) for unsupervised low-light image enhancement. This method decouples the relative illumination structure from absolute exposure levels by inferring it from reliable bright regions, preventing noise from biasing the estimate. RISE also incorporates a Dual-Metering Exposure Reference to adapt enhancement strength to individual scenes and diverse lighting conditions, achieving state-of-the-art performance on benchmarks and real-world tests.
