无线传输JPEG数据时，由于信道存在噪音，经常会发生偶然性错误或突发性错误，因此错误检测与恢复在无线传输JPEG图像中有着举足轻重的作用。由于JPEG图像对传输错误非常敏感，一个bit位的传输错误就会影响后续位的解码，从而造成图像质量的严重下降。传统的处理JPEG传输错误是采用错误掩藏与编码自同步方法。其中错误隐藏是使用插值的方法来恢复数据，但其会在一定程度上降低传输图像的质量；编码自同步方法则会影响传输数据的通用性。为了更好地检测与校正JPEG数据传输错误，提出了一种新的JPEG编码数据传输错误检测与恢复方法。该方法以图像相关性作为判别依据，使用全搜索的方法来恢复数据。通过对该方法可行性进行的理论分析和仿真的实验表明，该方法可以更好地恢复偶然性传输错误，并可极大提高无线传输JPEG图像的质量。

As Wireless communication channels exist noise,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.
