Research of unequal error protection method of wireless transmission for multispectral compression image

During the work of multispectral images, compressed image quality maybe descend or even not decoded because of wireless transmission electromagnetism interference. According to the characteristics of multispectral images, the performance of image wireless transfers channel, and the interior structure on JPEG2000 wireless image compression criterion, Unequal Error Protection scheme is put forward under different state of wireless transmission. Via various degrees correction-coding, three degrees Unequal Error Protection of image data are realized. Image decoding success rate and image quality are analyzed according to BCH,RS and Hamming coding and region of interest in the Gaussian white noise model and rayleigh fading model. The results shows that the unequal error protection method roughly improves decoding success rate, at the same time, almost not increasing bandwidth, flexibly enhances local partial image´s quality which is in favor of identifier in the region of interest.
