Paper Abstract

A surface distortion measure for a motion compensated image coding algorithm is described. This distortion measure provides a new approach to determining the rate of the residual quantizer in such an algorithm. The surface distortion measure (SDM) is a function of both the signal variance and the error variance. This functional relationship circumvents a major problem that is associated with using the ratio of these quantities as a quantizer design parameter. When the surface distortion measure is used as the fidelity criterion for the residual quantizer of the motion compensated image coding algorithm, superior data compression capabilities with little added distortion are achieved. A comparisqn of the results of using both SNR and the SDM as a fidelity criterion in a motion compensated image coding procedure is presented.
