Unequal protection of JPEG2000 code-streams in wireless channels

摘要

The rapid growth of wireless communication has resulted in a demand for robust transmission of compressed images over wireless channels. The challenge of robust transmission is to protect the compressed image data against loss in such a way as to maximize the received image quality. The paper addresses this problem; investigating unequal error protection of JPEG2000 compressed imagery. More particularly, the results reported in this paper provide guidance concerning the selection of JPEG2000 coding parameters and appropriate combinations of RS (Reed-Solomon) codes, for typical wireless bit error rates in the range 10/sup -4/ to 10/sup -3/.
