Abstract

On aviation mapping, compression image maybe not decode because of wireless transmission interference. UEP (unequal error protection) scheme is put forward about layer and block structure of JPEG2000 image compression method, and realizes three degrees UEP of data block, data header, image data via various degrees correction-coding under the condition of obstruct, naked and shade. BCH, RS and Hamming coding are simulated, and image decoding success rate and imagepsilas quality are analyzed according to different coding and ROI (region of interest) in the Gaussian white noise model and Rayleigh fading model. Results shows that the method we putted forward roughly improves decoding success rate, at the same time, almost not increasing bandwidth; flexibly enhances local reconfigurable imagepsilas quality which is in favor of identifier in the region of interest.
