CRISP: Progressive Illumination Curriculum for Recurrent Low-Light Video Enhancement with Semantic Priors

Low-light video enhancement requires the recovery of brightness, color, and fine spatial structures while preserving temporal coherence in the presence of noise and motion.

Key points

  • This paper presents CRISP, a recurrent framework trained using a progressive illumination curriculum.
  • Its two-frame recurrent architecture propagates information across successive frames to exploit temporal context beyond the immediate input pair.
  • This curriculum stabilizes recurrent training without introducing additional inference cost and yields the largest performance improvement among the components evaluated in the ablation study.
  • To further support structural reconstruction, the framework optionally incorporates frozen DINOv3 semantic features through adaptive layer normalization (AdaLN)-style modulation, without fine-tuning the foundation model.
