Abstract

If channel errors are introduced during the video transmission, we can apply error concealment techniques to reduce the transmission error effects by exploiting spatial and temporal redundancies of the video signal. Recently, motion vector recovery and motion compensation with the estimated motion vector has been one of the critical issues for the temporal-domain error concealment. In this paper, we prove that it is reasonable to use the estimated motion vector for concealing the lost macroblock by providing new macroblock distortion models. Based on the proposed distortion models, we develop several motion vector recovery algorithms.
