Abstract
This paper introduces a new framework of sequential error concealment techniques for block-based image coding systems. Unlike previous approaches which simultaneously recover the pixels inside the missing block, we propose to recover them in a sequential fashion. The structure of sequential recovery enhances the capability of handling complex texture patterns in the image and serious block loss situations during the transmission. Under the framework of sequential recovery, we present a novel spatially adaptive scheme to interpolate the missing pixels along the edge orientation. We also study the problem of how to fully exploit the information from the available surrounding neighbors with the sequential constraint. Experiment results have shown that novel sequential recovery techniques are superior to most existing parallel recovery techniques in terms of both subjective and objective quality of reconstructed images.
