%X This paper presents an error protection technique for SPIHT-coded image transmission in error-prone network.For the lowest and next lowest frequency coefficients,protection scheme based data hiding is performed.The lowest and next lowest frequency coefficients,which are taken as the hidden data,are extracted from the compressed bitstream,and embedded back into the same bitstream.The restored hidden data is used to conceal errors.The coefficients that cannot be recovered in other high frequency coefficients reconstruction are predicted through linear interpolation based on intra-subband or inter-subband correlation.Experimental results show that the proposed method achieves good and stable error performance with minimal additional redundancy.
