Shannon rate distortion theory
Rate–distortion theory was created by Claude Shannon in his foundational work on information theory. In rate–distortion theory, the rate is usually understood as the number of bits per data sample to be stored or transmitted. The notion of distortion is a subject of on-going discussion. Visa mer Rate–distortion theory is a major branch of information theory which provides the theoretical foundations for lossy data compression; it addresses the problem of determining the minimal number of bits per symbol, as … Visa mer Distortion functions measure the cost of representing a symbol $${\displaystyle x}$$ by an approximated symbol $${\displaystyle {\hat {x}}}$$. Typical distortion functions … Visa mer Suppose we want to transmit information about a source to the user with a distortion not exceeding D.

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
