We present a novel robust layered image transmission (LIT) design algorithm
for noisy channels. In the algorithm, the layered embedded zerotree wavele
t (LEZW) coding technique is used to encode the images for the transmission
of each layer. A new error protection allocation scheme based on genetic p
rogramming is then employed to determine the degree of protection for each
layer so that the average distortion of the reconstructed images after tran
smission can be minimized. Simulation results show that, subject to the sam
e amount of redundancy bits for error protection, the new algorithm outperf
orms other existing algorithms where equal-protection schemes are adopted.
