Yes, there are a lot. For example, NCMEC maintains databases of child porn hashes using photodna and other things.
Machine learning and other algorithms are used to identify images that end up in this database (and others).
Sadly, teaching machines what exploitation looks like is hard and it's not as simple as "identify things that have explicit sexual activity" and then "filter those things by people who appear to be 6 years old".
