Abstract
Aframework is proposed for iterative joint source-channel decoding
of JPEG2000 codestreams. At the encoder, JPEG2000 is used to perform
source coding with certain error-resilience (ER) modes, and LDPC
codes are used to perform channel coding. During decoding, the source
decoder uses the ER modes to identify corrupt sections of the codestream
and provides this information to the channel decoder. Decoding is carried
out jointly in an iterative fashion. Experimental results indicate that the
proposed method requires fewer iterations and improves overall system
performance.
