Loop-Mamba: A Loop Mamba with Degradation-Aware and Shared Memory for Old Photo Restoration
Loop-Mamba restores old photos by treating restoration as a progressive loop state evolution rather than repeated image reconstruction. It introduces a Semantic-Guided Degradation Estimator to model different types of damage and a Shared Structural Memory to maintain long-range structural consistency across iterations. This lightweight framework achieves superior quality and efficiency on old photo restoration benchmarks.
