Paper Abstract

In linear predictive coding, especially in adaptive linear predictive coding, channel errors tend to propagate destroying significant portions of an image. In this paper, an adaptive weighted median predictive coding scheme which is robust against channel errors is proposed. Neither overhead information nor error correction coding is needed. The scheme is applied to real images and is shown to provide much improved performance at high bit error rates (BER).
