How ResULIC Achieves Ultra‑Low‑Rate Image Compression with Semantic Residual Coding and Diffusion

The paper introduces ResULIC, a residual‑guided ultra‑low‑bitrate image compression framework that combines semantic residual coding, a compression‑aware diffusion model, and perceptual fidelity optimization to dramatically improve visual quality and outperform prior diffusion‑based methods on standard benchmarks.
