We present a technique to robustly transmit regions of interest in the JPEG2000 framework. The technique assumes a prioritized region of interest coding and optimally assigns channel protection to the coded data according to the importance of every packet in the final bit stream. The mean energy of the transform coefficients contained in a packet, and the distance of a packet from the region of interest, determine the importance of every packet. Channel protection is achieved by means of a concatenation of a cyclic redundancy check outer coder and an inner rate-compatible convolutional coder. Simulation results performed over a Rayleigh-fading channel show an improvement in the visual quality of the reconstructed images.
