A New Method for Detection and Correction Transmission Errors in JPEG Image
single-bit error and burst error containing N successive error bits may occur during JPEG-coded transmitting image over wireless communication system.Therefore error detection and correction play a very important role in transmission joint photographic experts group(JPEG) images.JPEG image is sensitive to transmission error.A single transmitting error in codeword will affect subsequent codeword and may result in a significant degradation.Error concealment and self-synchronizing codes are traditional methods to cope with this problem.The basic theory of error conecalment method is interpolation.So it will degrade image quality in some measure.On the other hand self-synchronizing codes need a specific coder.It will reduce the compatibility of JPEG images.For the sake of better decoding performance this paper proposed a novel algorithm for transmission error detection and correction.Base on image correlation
the proposed algorithm correct transmissive error with full search method.The paper also analysed the practicability of the algorithm.Based on the simulation results obtained in this study
the proposed approach is able to fit all the single-bit transmission error and improve the quality of JPEG image greatly.
