| Abstract | ||||
| Joint Photographic Experts Group (JPEG 2000) is an image compression standard which is recently became one of the most used techniques in image transfer, especially for satellite images. Unequal Error Protection (UEP) coding techniques can be used to increase image transfer immunity against channel noise. In UEP, the important parts of the image are protected using stronger codes than that used for the other parts. This paper proposes an UEP scheme by applying Low Density Parity Check Code (LDPC) for protecting the Region Of Interest (ROI) and headers (markers and marker segments) and Hamming code for protecting compressed data bits. A digital communication system which incorporates a Binary Phase Shift Keying (BPSK) as a common modulation technique is built for the purpose of verifying the proposed UEP scheme performance. The performance of the proposed UEP scheme is compared subjectively and objectively, to validate its superiority, with the traditional Equal Error Protection (EEP) scheme. | ||||
