摘要：
A DPCM system employing a median predictor, which is called the predictive median-DPCM(PM-DPCM), is proposed. An interesting property that in PM-DPCM transmission noise if often isolated and not propagated over the reconstructed signals is observed and is analyzed deterministically and statistically. In order to examine the performance characteristics of the PM-DPCM, it is applied to real image signals. The experimental results indicate that the PM-DPCM outperforms the standard DPCM when transmission errors occur, and that the former performs like the latter under noise-free conditions.
