Paper Abstract

This paper demonstrates a robust compression/decompression system for still image coding. The error resilience is obtained by substituting a regular Variable Length Coding (VLC) scheme with a Reversible Variable Length Coding (RVLC) scheme. The results show that this substitution increases the coder robustness significantly. Results on the substitutions are obtained by comparing the performance of RVLC to an early implementation of JPEG2000 (VM3.0B). Reversible Variable Length Coders can decode independently both from the beginning and the end of the sequences. This achieves an increased robustness to errors in that more codewords will be decoded than in a regular VLC, which can only decode from the beginning of the sequence. The gain of our coders in the region of interest, bit error rates ranging from 10-4 to 10-2, are in order of 2 dB over the VM3.0B. Visually the differences are significant.
