Title: SPATIO-TEMPORAL FADING SCHEME FOR ERROR CONCEALMENT IN BLOCK-BASED VIDEO DECODING SYSTEMS

Abstract: In this contribution we propose a new spatio-temporal fading scheme for block loss recovery in block-based video decoding systems. Based on a boundary error criterion obtained from temporal error concealment, either spatial, temporal, or fading of both methods is used for recovering lost image samples in one macroblock. The weights for fading are interpolated from the boundary error. A weighted absolute difference between well received macroblock boundary samples from the current frame and motion compensated macroblock boundary samples from the previous frame represents the boundary error. It is shown, that in case of transmission errors this method can successfully be used for block loss recovery.
