Abstract

JPEG2000 has a feature called region of interest (ROI). This feature can encode a restricted region in an image prior to its background (BG) region. In low bit rate compression, the code of the ROI region occupies the most part of the bit stream for the whole image by the rate control processing. To solve this problem, several progressive image quality control methods between the ROI and BG regions have been proposed. However they cannot realize fine relative image quality control between the ROI and BG region. This paper proposes a fine control method by one-path processing. The standard decoder of JPEG2000 part 1 can decode the coded data
