There are many ways to compare images, see ImageMagicks section on compare for further methods. RMSE root mean squared (normalized root mean squared) PAE peak absolute (normalize peak absolute) MSE mean error squared, average of the channel error squared MEPP mean error per pixel (normalized mean error, normalized peak error) MAE mean absolute error (normalized), average channel error distance Some metric options: AE absolute error count, number of different pixels (-fuzz effected) There are also many ways to output the differences via some metrics, e.g.: # compare -verbose -metric PSNR tux_orig.png tux_modified.png tux_difference.png To install it: sudo apt-get install imagemagick imagemagick-docĬomparing two images visually: compare -compose src tux_orig.png tux_modified.png tux_difference.png ImageMagick has the compare utility, which has several ways of comparing images.
