“…In Part 11 of the JPEG 2000 standard, wireless JPEG 2000 (JPWL) [54] defines techniques to increase the error resilience when transmitting codestreams over wireless network. JPWL specifies the tools such as forward error correction (FEC), interleaving and unequal error protection (UEP).…”

Abstract-In this paper, we develop a two-way multi-relay scheme for JPEG 2000 image transmission. We adopt a modified time-division broadcast (TDBC) cooperative protocol, and derive its power allocation and relay selection under a fairness constraint. The symbol error probability of the optimal system configuration is then derived. After that, a joint source-channel coding (JSCC) problem is formulated to find the optimal number of JPEG 2000 quality layers for the image and the number of channel coding packets for each JPEG 2000 codeblock that can minimize the reconstructed image distortion for the two users, subject to a rate constraint. Two fast algorithms based on dynamic programming (DP) and branch and bound (BB) are then developed. Simulation demonstrates that the proposed JSCC scheme achieves better performance and lower complexity than other similar transmission systems.

“…The analysis on the basis of network error simulations with a bit error rate in the range of 10 −2 to 10 −4 [14,15,20] is too coarse grain to show the subtle differences between the error concealment strategies. Commonly, errors occur The results of figures 7 and 8 show the averaged results for a test set of 100 images with a resolution of 512 times 288 each compressed with JJ2000 default parameters and a bitrate of 2bpp.…”

Abstract. In this work, JPEG2000 error resilience options and error concealment strategies are discussed and evaluated. Error resilience options and error concealment strategies have been employed to mimic attacks against selective / partial JPEG2000 encryption schemes. Thus the security evaluation of these selective / partial encryption schemes relies on the proper working of the JPEG2000 error concealment. Recommendations for JPEG2000 encryption given in previous work have to be reassessed on the basis of our results. Improvements to the error concealment code of the JPEG2000 reference software JJ2000 are presented.

“…The interleaving prevents from loosing important chunks of the bitstream at the same position but rather bursts the errors over the whole bitstream. The interleaving technique [13] is depicted in Fig. 10, where each ith word of the interleaved bitstream is constructed from the ith byte of each word from the original bitstream.…”

“…In error-prone conditions, the introduced schemes for image coding are compared to scalable JPEG2000. In this case, the different parts of the JPEG2000 stream are interleaved [13] and then protected with Reed Solomon (RS) [14] codes. Moreover, the error resilience tools of JPEG2000 are switched on to enable the recovery from errors present in the stream.…”
