1. A method implemented by a network device, the method comprising:
determining, by at least one processor of an encoder, a region of interest in an image;
partitioning, by the at least one processor, the image into a plurality of blocks;
applying, by the at least one processor, a transform to the blocks to obtain a plurality of coefficients;
assigning, by the at least one processor, the coefficients into quality layers of decreasing priority, each subsequent layer including data to incrementally increase quality of a reconstructed image;
positioning, by the at least one processor, region of interest coefficients in one or more image data packets by quality layer and in an order of decreasing priority;
positioning, by the at least one processor, remaining coefficients in the image data packets with a lower priority than the region of interest coefficients, the remaining coefficients positioned by quality layer and in the order of decreasing priority;
storing, by a memory of the encoder, the image data packets; and
transmitting, by a transmitter, the image data packets over a network.
