An Adaptive Source-Channel Coding with Feedback for Progressive Transmission of Medical Images
Figure 12
The decoded image with variable length of parity codes over the noisy channel.
(a) A background image and the location of RoI selected in the
center of image reconstructed after stage ,
(b) the reconstructed image after stage , no
error subblocks are found in the reconstructed image because the lengths of
parity codes are adjusted automatically based on the previous
volume of incorrect data in the receiver, (c) the reconstructed image after
stage ; the lengths of parity bits in stage 3
are as same as in stage 2 because no incorrect data was found in the
reconstructed image after stage 2, (d) the complete transmitted image with no
error subblocks.
