DOIAbstract
In this paper, we address the problem of image transmission over unreliable networks, such as the Internet, where packet losses occur. The most recent literature indicates that multiple description (MD) is a promising coding approach to handle this issue. The traditional spatial domain MD image coding techniques usually result in the very low coding efficiency. This paper proposes a new architecture for MD image coding, which is based oil directional wavelet transform that removes redundancy among spatial and wavelet domain. In addition, a novel interpolation method using reproducing kernel filter (RKF) reconstructs one description with full resolution. The results show that the proposed technique is far better than other existing method. (...
