Two-dimensional soft-input source decoding for robust transmission of compressed images
Jörg Kliewer, Norbert Goertz · Electronics Letters · 2005
The transmission of compressed images over highly corrupted channels is addressed. The implicit residual redundancy inherent in the quantised subband images and the bit-reliability information at the channel output are utilised for error protection. As a novelty a known estimation technique is extended to the two-dimensional case, where both horizontal and vertical correlations are exploited. Especially for very noisy channels the quality of the reconstructed image is greatly increased compared to one-dimensional approaches.
