This paper presents an error-resilient coding technique combined with error concealment for embedded wavelet coders. The coded images are partitioned into packets and protected by multiple descriptions. Each packet contains an independent spatial-orientation tree and duplicated copies of other root wavelet coefficients. At decoding, the coefficients that cannot be recovered are predicted through linear interpolation based on inter-subband correlation. Experimental results show that the proposed method achieves good and stable error performance with minimal additional redundancy.
