Overview

Large-scale dataset improves low-light video enhancement, demonstrating effectiveness in semantic segmentation and temporal coherence.

Key Points

  • EvLight++ enhances low-light video quality by 1.37 dB over single image methods and 3.71 dB over video-based methods.
  • The dataset consists of over 30,000 pairs of frames and events, achieving spatial alignment precision under 0.03mm.
  • This novel method employs SNR-guided regional feature selection and a recurrent module for improved temporal coherence.
  • Experiments indicate a 15.97% improvement in mIoU for semantic segmentation, underscoring its application in real-world scenarios.
