Abstract

A dynamic mode-weighted error concealment method is proposed for video packets transmitted over noisy channels in this work. We first introduce two error concealment approaches. One is to reconstruct lost pixels by interpolating candidate pixels indicated by neighboring motion vectors. The other is to estimate the motion vector by a side matching algorithm. Four corrupted block reconstruction modes are described based on the two error concealment approaches. Then, the value of an erroneous pixel is replaced by a weighted sum of those reconstructed by two modes. The property of the weighted sum is analyzed. It is shown that the optimal weighting coefficients can be expressed as a formula in terms of the error variance and the correlation coefficients associated with the reconstruction modes. Furthermore, based on the decoder-based error tracking model, these weighting coefficients are dynamically updated to minimize the instant propagation and concealment error variance. Extensive simulations are provided to demonstrate that the proposed method can lead to a satisfying performance in an error-prone environment.
