Abstract
A differential pulse code modulation (DPCM) system employing a median predictor, which is called the predictive-median-DPCM (PM-DPCM), is proposed. It is shown that the PM-DPCM is resistant to transmission errors. Specifically, it is observed that transmission errors are often isolated and not propagated in the PM-DPCM images. The characteristics of PM-DPCM are analyzed, and its performance is compared with those of other DPCM systems through experiments. 1-D and 2-D PM-DPCM systems are defined and their properties are examined. Some statistical properties of PM-DPCM are derived
