Robust image compression with packetization: The JPEG-2000 case

Multimedia applications running over wireless or other error prone transmission media require compression algorithms that are resilient to channel degradation. This paper presented a data packetization approach to make the emerging ISO JPEG-2000 image compression standard resilient to transmission errors. The proposed technique can be easily extended to other wavelet-based image codec schemes. Extensive simulation results shown that, with the proposed approach, a decoder is able to recover up to 8.5 dB in PSNR with a minimum overhead, and without affecting coding efficiency and spatial/quality scalability. Finally, the proposed approach supports unequal error protection of the wavelet subbands.
