The rate distortion function of a source represents the minimum information rate at which the source can be transmitted to be reproduced within some prescribed average distortion. This function is of considerable interest in source coding and data compression problems. One of the limitations of the usefulness of rate distortion theory is the difficulty in evaluating the rate distortion function for many sources and distortion measures. The research presented in this report is concerned with the evaluation of the rate distortion function for various classes of sources and distortion measures. Author
