Invertible Diffusion Models Accelerate Image Reconstruction – TPAMI 2025

The TPAMI 2025 paper by researchers from Peking University, KAUST, and ByteDance introduces Invertible Diffusion Models (IDM), an end‑to‑end trainable, memory‑efficient diffusion framework that narrows the gap between noise estimation and image reconstruction, reduces sampling steps from 100 to 3, boosts PSNR by 2 dB, and speeds inference up to 15×, with open‑source code available.
