Why does Adobe think these two images of different owls are similar?
I'm new to Adobe Stock and have been adding a few images recently - I have had a few rejected where I had some (deliberate) out of focus areas or had post processed to B&W or applied other artistic effects - that's fine and understand if Adobe Stock doesn't want those (other stock sites are happy to accept them). But the one that I find odd is that I had an image of an owl accepted but then another image of a totally different owl rejected saying it was too similar to the first! I even resubmitted in case it was done in error and it got rejected again.
Here is the one that was accepted:

And the one that was rejected as being too similar:

Can anyone offer any explanation other than it is not a human doing the comparison but some sort of machine learning that only takes into account a few simple parameters... It's not a big deal (and again other stock sites were happy with both) but very curious how Adobe handle this.
Thanks
