Abstract

A new error concealment algorithm for recovering the lost or erroneously received motion vectors is presented. It combines the overlapped motion compensation and the side match criterion to make the effect of lost motion vectors subjectively imperceptible. The side match criterion takes advantage of the spatial contiguity and interpixel correlation of image to select the best-fit replacement among the motion vectorsof spatially contiguous candidate blocks. Particularly, to mask the blocking artifacts, we incorporate an overlapping technique to create asubjectively closer approximation to the true error-free image.
