Temporal Error Concealment using the Concealed Boundary Pixels and Boundary Region Feature

In this paper, we proposed a temporal error concealment (EC) using the concealed boundary pixels and the adaptive block matching method. The proposed boundary matching method improves the spatial correlation of the macroblocks (MBs) by reusing the pixels of the concealed MB to estimate a motion vector of a error MB. The adaptive block matching method inspects horizontal edge and vertical edge feature of the error MB and it conceals the error MB in reference to stronger edge feature.
