A simple duplicate image finder.
Checks the similarity between two images, using the SSIM algorithm implemented
by dssim-core
. Works on JPG and PNG images of any size by first rescaling
them to 200x200 internally.
Runs multithreaded, every image is checked against every other one and there is no heuristic for e.g. finding likely candidates early, so while this is somewhat optimized, checking many files will likely still be very slow.
Note: I am rather inexperienced with Rust, so there will definitely be some dumb code here.
Either run cargo install dupimg
, or clone this repository and run
cargo install --path .
from the project root.
dupimg [-r directory1/ directory2/ ...] file1.jpg file2.png ...
<IMAGE 1> # path to first image
<IMAGE 2> # path to second image
SSIM: 0.0... # positive and unbounded; lower values indicate a closer match
The threshold for displaying a match may be set by e.g. -t 0.01
. Only matches
with a SSIM smaller or equal to this threshold will be displayed.
The default is 0.1, as this tends to give good results with very few false positives.
-r
may be specified to enable traversing specified directories.
When recurse is enabled, only PNG and JPG files will be checked. This also applies to filenames specified on the command line.
