man findimagedupes (Commandes) - finds similar or duplicate images

NAME

findimagedupes - finds similar or duplicate images

SYNOPSIS

findimagedupes [options] file1 file2

DESCRIPTION

This manual page documents briefly the findimagedupes command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

findimagedupes is a commandline utility which performs a rough "visual diff" to two images. This allows you to compare two images or a whole tree of images and determine if any are similar or identical. The program can optionally export a GQView compatible collection file, so you can deal with the duplicates visually. On common image types, findimagedupes seems to be around 98% accurate.
