Paper Abstract

A pre/post-filtering framework for DCT image coding has been proposed recently. Together withWiener filtering technique, the new framework has been investigated for error resilient image coding. In this paper, after a review of existing methods, we analyze the limitation associated with one of the current design criteria, the reconstruction gain, and propose an alternative that offers better control of the error distribution, thereby improving the visual quality of the reconstructed image in the presence of transmission error. The performance of the proposed scheme is demonstrated through various multiple description coding (MDC) simulations.
