Abstract:

We propose a new method for error correction coding based on shape preserving characteristic of the phase-only transform. It creates 2 descriptions by phase mapping and pixel interleavingIt synthesizes the image with only a little distortion by phases and damaged magnitudes. The receiver decodes a high quality image when both descriptions are received. Images, badly damaged due to the high error rate in transmission, can also be recovered from the only available description with an acceptable quality. Simulations show that it outperforms schemes such as pixel interleaving and phase scrambling by about 1.5~3 dB in peak signal to noise ratio (PSNR).
