Diffusion models enable new adaptive lossy compression

Researchers have developed a novel training-free framework that utilizes pre-trained diffusion models to navigate the rate-distortion-perception (RDP) tradeoff in lossy compression. This approach integrates a reverse channel coding module with a unique score-scaled probability flow ODE decoder. The framework theoretically achieves optimal RDP functions in Gaussian cases and empirically demonstrates flexibility in adapting to different compression needs using existing diffusion models. AI
