The compare function has many "difference" metrics. See http://www.imagemagick.org/Usage/compare/#statistics. You will have to look in the compare.c code to see how they are implemented.
i used compare command of imagemagick to detect near duplicate images. Though i refer source code and several documentations i couldn't find which code part handles this compare command. Can you please tell me which algorithm/code handles this compare command
