Sounds like you want to convert raster images to vector. https://vectormagic.com/ https://vectormagic.com/ is a commercial version.

  Thats not actually my problem. For a good quality print I can do this with no issue. (I use imagetracer.js in my web app) but the problem I have is many prints that come through smudged or otherwise damaged. In those cases I have to retrace them, sometimes taking a decent amount of artistic license using what I know about how other prints looks.

    How many samples do you have of smudged prints that have been corrected? Can you also artificially smudge prints to create a training set? Then an interesting solution might be possible!

      I currently only have about 100 fixed up image sets. One of the other commenters pointed me to a blog that mentioned this software for generating realistic finger print images: https://dsl.cds.iisc.ac.in/projects/Anguli/ https://dsl.cds.iisc.ac.in/projects/Anguli/ which could then be artificially smudged. There seems to be a dataset out there somewhat that has already done this (https://competitions.codalab.org/competitions/18426 https://competitions.codalab.org/competitions/18426) but I can't find out where to download it.

        I would advise against completely synthetic prints, you want to model your training data as close to reality as possible! Can't you just blur other finger prints you have?
