Abstract:

A two-level, hybrid-optimization scheme is proposed for rate allocation of JPEG2000 (J2K) transmission over noisy channels. It combines forward error correction (FEC) and the J2K error resilience modes to minimize the expected end-to-end image distortion. Subject to a total target bit rate, it forms fixed-length channel packets in a straightforward manner. The proposed scheme utilizes the source distortion rate characteristics and the BER statistics of the available channel codes. It has complexity less than 0 (R/sup 2/) for a specific J2K codestream, where R is the number of available channel code rates. Performance results with both RCPC and turbo codes for fixed-length source packets are provided to show the effectiveness of the scheme.
