摘要

对于无限大图像

I定义了一个失真率函数d(R/I

R时渐近可达的失真下限.本文证明了其编码定理和逆定理.它不必已知I

的概率特性.

Abstract

For every individual images

we define a distortion-rate function

d(R/I

) which is shown to be an asymptotically attainable lower bound on the distortion that can be achieved for

by any finite-state encoder operating at a fixed output rate

.This is done by means of a coding theorem and its converse.No probabilistic characterization of

is assumed.
