We use adv212 compressing 16bit monochrome still image, the compressed image encountered fuzzy problem, 512 * 512 size image compression ratio is set to about 60: 1, but the jp2 filesize only 1kB, the actual compression ratio is 512: 1
Source image pixel value is small, of about the lower 10 bit. we suspect and stepsize set up, when using kakadu software ,reault is much better (set qstep to 1/256 or 1/10000).
we failed setting adv212 stepsize paramter .after the soft-rebooting, stepsize recovery to default value.if we do not enablesoft-rebooting, the loadss will not be cleared,Adv212 can not start encoding. The situation does not match the description of the programing guide.
