Abstract
A new error resilience tool is proposed for robust JPEG 2000 imaging over noisy channels. In particular, a modified encoder based on an MQ arithmetic coder with forbidden symbol is introduced, along with a maximum likelihood error-correcting MQ decoder. The proposed technique features error detection, error concealment and error correction capability, thus adding new useful functionalities to JPEG 2000. Experimental results show that this technique largely outperforms the standard JPEG 2000 error resilience tools as for error concealment and hard/soft channel decoding.
