Removing Channel Error Artifacts in JPEG 2000 Coded Images

Segmentation symbol is an error resilience feature in JPEG 2000 image coding standard. When this feature is used, not detecting the segmentation symbol at the end of a bit plane by decoder, indicates that an error has occurred within that bit plane. However, a detected and correctly decoded segmentation symbol does not guarantee that the bit plane is error free. In this paper, an error concealment method is proposed for removing artifacts caused by the damaged bit planes that were not detected by the segmentation symbol. The proposed method provides a model for coded bit planes in the encoder and uses this model for error concealment in decoder. Simulation results show that the proposed method can effectively remove artifacts and improve the quality of corrupted images by up to 6 dB in PSNR.
