I am trying to convert png images into JP2 with sampling factor. I am using imagemagick tool for conversion, as they mentioned in docs -sampling-factor is used for sampling but it did not work. http://ftp.icm.edu.pl/pub/unix/graphics/ImageMagick/www/jp2.html
convert wizard.png -colorspace YUV -sampling-factor 2,2 wizard.jp2
My command, it did not work
convert test/images/kodim$i.png -quality $(($j*5)) -colorspace YUV -sampling-factor 4,2 test/JP2/kodim$i/`printf "%02d" $j`.jp2
