WebbAbstract—Rate-distortion-perception theory generalizes Shannon’s rate-distortion theory by introducing a con-straint on the perceptual quality of the output. The per-ception constraint complements the conventionaldistortion constraint and aims to enforce distribution-level consisten-cies. In this new theory, the information-theoretic limit Webbversus algorithmic suﬃcient statistic (related to lossy compression in the Shannon theory versus mean-ingful information in the Kolmogorov theory), and rate distortion theory versus Kolmogorov’s structure function.
