Some? Literally all are clearly based on pornography.

First is veg&butthole, then boobs, next is doggy style etc etc (edit: it seems the order isn't consistent. So I'm likely seeing different images then you.)

You can go through them all and see the original pornography if you look at the shapes. To me, it looks more like they started with the real images and tweaked them to make them artsy.

I don't know, this sounds a bit like a Rorschach test to me.

I love this comment. I have no idea how these were generated, but even starting with random noise it's possible to end up with vaguely human shapes if that's what originated the hashes to begin with.

These images could be a joke, as I don't think we have a clear technical documentation of how these hashes are generated. Computer vision? Vectors? Face recognition software? It's definitely not a naive hash.

Edit: seeing the other comments in this thread referencing Twitter, it looks like it's more naive than expected, as the hash is resistant to resizing, but not to cropping. The implementation can change at Apple's discretion, though.
