Is it possible to find duplicate photos (including resized and color-corrected ones) using a neural network?

There is a large archive of photos for 10 years. It contains a large number of duplicate photos, including those with a little processing (resizing, color matching, cropping the edges). I really want to put things in order in the photo archive, it would be easier if the photos had the correct dates, but this is not always the case. Some cameras did not set time tags, and some set January 1, 2004, when the case was in fact in 2012.
Is it possible to use neural networks to find all duplicate photos, including inaccurate ones? I ndex pictures seem to know how.

see Opencv + SIFT +SURF
, like neurons, all give probabilistic estimates, i.e. up to one

Just use the free pHash (perceptual hash) library.

Siamese networks. But pHash is really simpler.
