%description
This tool computes (dis)similarity between two or more PNG images
using an algorithm approximating human vision.

Comparison is done using the SSIM algorithm at multiple weighed
resolutions.

%description -l pl.UTF-8
To narzędzie oblicza (nie)podobieństwo dwóch lub większej liczby
obrazów PNG przy użyciu algorytmu przybliżającego ludzkie widzenie.

Porównywanie jest wykonywane algorytmem SSIM z wieloma ważonymi
rozdzielczościami.
