Abstract

The residual redundancy in compressed two-dimensional sources is described by a second order Markov model which is made available to a MAP receiver which employs a generalization of the Viterbi algorithm. The method is applied to 3-bit DPCM picture transmission over a binary symmetric channel; and it is found that the inclusion of vertical memory results in significant performance enhancement
