Abstract
A method transcodes an image in the form of an encoded input bitstream. The input bitstream includes quality layers, each quality layer includes a resolution levels, each resolution level includes components, each component includes precincts, and each precinct includes a packet partition location, a header length, and a body length. The input bitstream is decoded partially to obtain a structure of the encoded input bitstream. Coordinates of a region-of-interest in the image are specified, and progressive parameters are defined. The partially decoded input bitstream is then encoded according to the structure, the coordinates, and the progressive parameters to obtain an encoded output bitstream.
