Copyright law is the right to control a set of specific kinds of actions. A complete list of which ones is at https://www.copyright.gov/what-is-copyright/. "Inputing the work to a computer program" is not in the list of actions. Whether or not the result of running that program may violate copyright is a question of fact based on what the program does.

As for what it does, my non-lawyerly opinion is that it is no different than a human artist looking at paintings then imitating the style. Which is very much legal.

That said, a case can be made for derivative works. I don't think it is a very good case, but a case can be made for it.
