[Feature request] handle different resolutions

[ChameleonScales]

Hi,
After a few tests on hand drawing images it seems your project blows all image comparison programs I've used out the window in terms of outputting distances that result in a good sorting of image couples (e.g. DupeGuru, Pixiple, Awesome Duplicate Photo Finder and more).
However, what it mainly lacks that all other programs have is supporting images of different dimensions.
Unless your project has been outperformed by another one, I think it would be amazing if such a feature were implemented, as it could get closer to becoming a widely used image comparison tool, provided someone wants to come in and add a GUI to it.

I might have spoken too early about blowing the other programs out the window. it seems my tests were very lucky. When I changed the image resolutions the results were completely different. Maybe it does not handle hand drawings and line art so well.
