Abstract :
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 multiple description (MD) as a promising coding approach to handle this issue. The traditional spatial domain multiple description image coding techniques usually results in the very low coding efficiency. This paper proposes a new architecture for multiple description image coding. The proposed architecture is based on directional wavelet transform in the wavelet domain that removes redundancy among wavelet coefficients. 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 existed method
