摘要

JPEG2000图像的分层特性要求采用不等差错保护方法以实现高效传输

本文提出了一种新型的不等差错保护方法

对不同位平面采用不同码率的抗差错算术码进行编码.与基于信道编码的不等差错保护方法相比

该方法保持了压缩码流的结构

避免了复杂的信道成帧过程.与已有的基于抗差错算术码的等差错保护方法相比

该方法提高了传输图像的质量.

Abstract

The hierarchical structure of JPEG2000 stream calls for unequal error protection (UEP) schemes to achieve robustness efficiently.In this paper

a novel unequal error protection scheme is proposed for JPEG2000 image transmission

which encodes each bit-plane with ERAC of different code rate.Comparing with UEP schemes based on channel coding

the proposed scheme reserves the structure of JPEG2000 standard streams and avoids complicate channel framing process.Comparison with published equal error protection scheme proves the effectiveness of this method.
