• simagef - find similar images - LinuxLinks

  It uses the image-match crate to generate signatures for images and compare them. An option to match images using pixel comparisons via the image-compare crate is also available with the pixel feature flag.

  simagef is faster than the findimagedupes Perl script, but might not produce identical results – not even across the signature/pixel modes, and is not designed to be a drop-in replacement.
