Abstract

In this paper, we propose a passive error concealment scheme for the reconstruction of wavelet coded images which are damaged due to packet loss. The proposed interpolation scheme calculates a lost coefficient from its neighbors while adapting the interpolation weights to the image correlation in each direction. All subbands are processed independently which allows a fast, parallel execution. This is interesting for real-time video applications such as two way video communication. The results demonstrate that the proposed scheme outperforms the existing schemes of similar complexity, both in terms of mean squared error and visually.
