LearnIR: Posterior Sampling for Image Restoration – Face Shadow Removal & Dehazing (ICLR 2026)

LearnIR tackles real‑world image restoration under heterogeneous degradations by training a lightweight network to predict gradient‑correction distributions for diffusion posterior sampling without a forward operator, and adds a dynamic‑resolution module that further suppresses noise, achieving state‑of‑the‑art PSNR, SSIM and LPIPS on multiple benchmarks.
