Abstract :
We investigate the residual redundancy in the Shapiro (1993) and Said-Pearlman (see IEEE Transactions on Circuits and Systems for Video Technology, vol.6, no.3, p.243-50, 1996) wavelet-based image compression algorithms. The goal is to use redundancy inherent in the output of these source coders to provide joint source-channel decoding in order to improve the error correction/detection performance for transmission across a noisy channel.
