SlimDiffSR: Toward Lightweight and Efficient Remote Sensing Image Super-Resolution via Diffusion Model Distillation

Ce Wang, Wanjie Sun, Zhenyu Hu

SlimDiffSR distills a diffusion model into a single-step student network that runs 200 times faster and uses 20 times fewer parameters for remote sensing super-resolution.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

SlimDiffSR attains up to 200× inference acceleration and a 20× reduction in model parameters compared with multi-step diffusion models, while achieving competitive perceptual quality and clearly outperforming existing lightweight diffusion baselines in efficiency.

C2weakest assumption

That the uncertainty-guided timestep assignment and structured pruning with frequency- and direction-separable convolutions plus MMD distillation will preserve generative quality on remote sensing data without significant degradation or domain-specific failure modes.

C3one line summary

SlimDiffSR uses uncertainty-guided timestep assignment and remote-sensing-tailored pruning plus MMD distillation to create a diffusion SR model with 200x faster inference and 20x fewer parameters while keeping competitive quality.
