    JPEG2000 supports Region-of-Interest (ROI) for preferential display. In this paper, an approach to extract ROI automatically from JPEG2000 bitstream is considered. By using the ROI, transcoding from the normal JPEG2000 bitstream to the one with ROI is achieved. The validity of the proposed method is confirmed by subjective tests.
