Sorry for late reply,
We have open-sourced current version of our algorithm on CC BY-NC 4.0 license. You can find it on https://github.com/maciej3031/comixify
Demo application is not the best when it comes to architecture (especially considering the level of interest), it would be useful to have some task queue like celery.
But we're still working on improvements!
