Abstract

This paper presents a correlation model based error concealment method for Polyphase Downsampleing (PD) applied multiple description coding (MDC) using H.264. With MDC, when one description is lost due to errors, the lost description can be reconstructed from other descriptions correctly received. The PD based MDC provides coded stream capability of reconstructing pixels in the lost description from neighboring pixels which are coded in other descriptions. The proposed error concealment method explores correlation between pixel to be concealed and its neighboring pixels, then applies correlation model based concealment method to reconstruct the lost pixels. Simulation results show that the proposed method improves coded stream error resiliency performance by an average 0.62 dB PSNR enhancement in comparison with an existing PD based MDC method.
