Error concealment algorithm using interested direction for JPEG 2000 image transmission
The newly defined JPEG 2000 delivers scalable and region-of-interest images with lower bit rates in Internet and wireless communications. However, any data loss in the JPEG 2000 bitstream affects the consequent bitplanes and even possibly destroys the whole picture. We propose a new algorithm to recover the damaged bitplane data according to the interested directional pattern in the subband. Simulation results show that the proposed concealment algorithm can achieve much smoother edges on the reconstructed image.
