Sherwood and Zeger protected a zero-tree based embedded wavelet code sent through a memoryless noisy channel by using cyclic redundancy detection codes (CRC) and channel correction codes. Chande and Farvardin proposed an optimal joint source-channel allocation strategy for such systems. We show how to accelerate their algorithm without quality loss. For grey scale test images of size 512 x 512, our speedup factors ranged from 1.2 to 6 for total bit rates between 0.25 and 1.0 bits per pixel. Moreover, by using turbo codes as channel codes, we obtained competitive peak-signal-tonoise ratio (PSNR) results.</dcterms:abstract> <dc:creator>Hamzaoui, Raouf</dc:creator> <dc:rights>deposit-license</dc:rights> <dcterms:issued>2003-11</dcterms:issued> <dc:creator>Saupe, Dietmar</dc:creator> <dc:contributor>Hamzaoui, Raouf</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-06-27T07:16:51Z</dc:date> <dc:contributor>Saupe, Dietmar</dc:contributor> <dc:creator>Stankovic, Vladimir</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/23141"/> </rdf:Description> </rdf:RDF>
